SUMMARY
Inspite of the realization and studies on the use of microorganisms in degrading hydrocarbons there has been very little work on indigenous white-rot fungi in Nigeria, a leading oil – producing country. The ability Lentinus subnudus to mineralize soil contaminated with various concentrations of crude oil was tested. Organic matter and carbon were higher than the control at all concentrations of crude oil contamination in soils incubated with L. subnudus for 3 months. Nutrient contents were generally higher after 6 months of incubations except potassium levels which were not significantly different from the control. As for the total petroleum hydrocarbon (TPH) in crude-oil contaminated soils; the highest rate of biodegradation was at 20% concentration after 3 months and 40% after 6 months of incubation.

SUMMARY
Studies were carried out to investigate the degradation of agricultural wastes by Pleurotus tuber-regium (Fries) Singer and Lentinus subnudus (Berk), both Nigerian edible mushrooms and the digestibility of the degraded wastes by ruminants using the sawdust of Mansonia altissima, rice straw and cocoa husks as wastes. Pleurotus tuber-regium degraded rice straw better, having 45.4% dry matter degradability (DMD) and for L. subnudus 47.2% compared to 29.6% DMD and 30.6% DMD in cocoa husks. However, in sawdust of M. altissima 22.4% DMD and 26.0% DMD were recorded for the two mushrooms, respectively. Incubation of all the substrates for 180 days enhanced their degradation. At all the periods of incubation, the lignin content in the substrates degraded by P. tuber-regium and L. subnudus was recorded to be 6.97% and 8.45% in rice straw compared to 13.6% and 11.88% lignin in cocoa husks, respectively. However, the highest lignin content was recorded in sawdust of M. altissima and up to 17.19% could be degraded by P. tuber-regium and L. subnudus.
Adenipekun, C.O. (2008). Bioremediation of engine-oil polluted soil by Pleurotus tuber-regium Singer, a Nigerian white-rot fungus. African Journal of Biotechnology 7 (1): 55 – 58.
SUMMARY
White-rot fungi have been used in various parts of the world for bioremediation of polluted sites. Pleurotus tuber-regium was noted to have the ability to increase nutrient contents in soils polluted with 1 – 40% engine-oil concentration after six months of incubation. P. tuber-regium increased organic matter, carbon and available potassium 5.19%, 2.99% and 0.97 meq/100g respectively compared to 4.41%, 2.56% carbon and 0.66 meq/100g, respectively in the control. However, higher values of 0.32% nitrogen, 11.42 ppm phosphorus and pH 6.94 were obtained in the control compared to 0.16% nitrogen, 9.32 ppm phosphorus and pH 5.93 in soils incubated with the fungus. The fungus brought about an increase in copper content in engine oil polluted soils at 10% concentration followed by a decrease at 20 and 40% concentrations. Bioaccumulation of zinc and nickel was recorded at 20% engine-oil concentrations.

SUMMARY
This study was conducted to test the efficacy of an indigenous white rot fungus Lentinus squarrosulus in degrading engine oil in soil. Flasks containing sterilized garden soil (100g) moistened with 75% distilled water (w/v) were contaminated with engine oil 1, 2.5,grading engine oil in soil. Flasks containing sterilized garden soil (100g) moistened with 75% distilled water (w/v) were contaminated with engine oil 1, 2.5, 5, 10, 20 and 40% w/w concentrations, inoculated with L. squarrosulus and incubated at room temperature for 90 days. Levels of organic matter, pH, total hydrocarbon and elemental content (C, Cu, Fe, K, N, Ni, Zn and available P) were determined post-fungal treatment. Results indicate that contaminated soils inoculated with L. squarrosulus had increased organic matter, carbon and available phosphorus, while the nitrogen and available potassium was reduced. A relatively high percentage degradation of Total Petroleum Hydrocarbon (TPH) was observed at 1% engine oil concentration (94.46%), which decreased to 64.05% TPH degradation at 40% engine oil contaminated soil after 90 days of incubation. The concentrations of Fe, Cu, Zn and Ni recovered from straw/fungal biomass complex increased with the increase of engine-oil contamination and bio-accumulation by the white-rot fungus. The improvement of nutrient content values as well as the bioaccumulation of heavy metals at all levels of engine oil concentrations tested through inoculations with L. squarrosulus is of importance for the bioremediation of engine-oil polluted soils.

SUMMARY
Objective: To investigate the effect of different concentrations of spent engine-oil on the growth of okra (Abelmoschus esculentus) plants.
Methodology and Results: 4.5kg topsoil was mixed with 0.2, 0.4, 0.6, 0.8, 1.0, 2.0 and 3.0% (w/v) of spent engine-oil (SEO). The control was not mixed with SEO (0%). The seeds were sown on these soils and monitored on alternative days. Parameters monitored were chlorophyll and relative water contents of the plants were analyzed after harvest. SEO contamination adversely affected growth and some physiological parameters, depending on concentration. The growth parameters were reduced by higher concentration of the oil. However, 0.2 and 0.4% SEO did not reduce these parameters. The highest relative water content (78.4%) was found in the control plants, followed by those treated with 0.2% spent oil (51.89%), the least being those treated with 0.6% spent oil (1.71%). Chlorophyll contents of okra plants were also reduced by the spent engine oil treatment, highest being recorded in the control plants (0% SEO) and the least were those exposed to 0.4% SEO. The plants grown on treated soil also showed chlorosis and necrosis symptoms at higher oil concentrations (0.6 – 3.0%).
Conclusion and Application of Findings: These results indicate that contamination of soil with spent engine oil at very low concentration (0.2%) has no significant (P < 0.05) effect on okra plants growth while the higher concentrations adversely and severely affect plant growth. Indiscriminate spillage of spent engine oil affected okra physiology and growth. Therefore, spent engine oil should be properly disposed.

SUMMARY
Lentinus squarrosulus Mont. is an important tropical edible and medicinal mushroom distributed across sub-Saharan Africa and most parts of Asia. Intrastock mating study was performed using single spore isolates (ssi) from a wild strain (MBFBL 201). Mycelia growth and morphology characterization indicated that milled corn straw agar (CSA) medium best supports mycelia growth compared to two other media: potato dextrose (PDA) and yeast peptone soluble starch agar (YPSS). The results from ssi pairings and analysis confirmed a tetrapolar mating system for L. squarrosulus. Further characterization of the resulting dikaryons indicated that the growth rate of the parent monokaryons does not affect the growth rate of the resulting dikaryon. Primordial formation in the resulting dikaryons with the fastest growth rate was 12 days after inoculation. Under similar conditions, MBFBL 201 and another wild strain, MBFBL 269, produced primordial after 28 and 32 days, respectively, indicating that intrastock breeding could be an effective method for obtaining improved strains of L. squarrosulus. Further characterization to test growth and performance in order to obtain high-yield strains for use in commercial cultivation is ongoing.

Lignocellulotic enzyme activities and sugar release from corn stalk under solid state fermentation. World Journal of Microbiology and Biotechnology 28(5): 1961 – 1966.
SUMMARY
Lentinus squarrosulus Mont., a high temperature tolerant white rot fungus that is found across sub-Saharan Africa and many parts of Asia, is attracting attention due to its rapid mycelia growth and potential for use in food and biodegradation. A solid state fermentation (SSF) experiment with L. squarrosulus (strain MBFBL 201) on cornstalks was conducted. The study evaluated lignocellulolytic enzymes activity, loss of organic matter (LOM), exopolysaccharide content, and the release of water soluble sugars from degraded substrate. The results showed that L. squarrosulus was able to degrade cornstalks significantly, with 58.8% LOM after 30 days of SSF. Maximum lignocellulolytic enzyme activities were obtained on day 6 of cultivation: laccase = 154.5 U/L, MnP = 13 U/L, peroxidase = 27.4 U/L, CMCase = 6.0 U/mL and xylanase = 14.5 U/nL. L. squarrosulus is a good producer of exopolysaccharides (3.0 – 5.13 mg/mL). Glucose and galactose were the most abundant sugars detected in the substrate during SSF, while fructose, xylose and trehlose, although detected on day zero of the experiment, were absent in treated substrates. The preference for hemicellulose over cellulose, combined with the high temperature tolerance and the very fast growth rate characteristics of L. squarrosulus could make it an ideal candidate for application in industrial pretreatment and biodelignification of lignocellulosic biomass.

SUMMARY
Auricularia auricula (St. Amans), a white rot fungus, was cultivated on Mansonia altissima (A. Chev) sawdust supplemented with 0, 5, 10, and 20% brewer’s grain (BG), corn chaff (CC), oil palm fibre (OPF), Sorghum bicolor chaff (SC) and wheat bran (WB). Sawdust supplemented with 20% WB showed the fastest mycelial colonization (9 days), and density. However, sawdust supplemented with 20% BG was the first to fructify (35 days) whereas the highest yield of fruit-bodies (7.33g) was recorded for sawdust supplemented with 10% BG after 39 days. The highest biological efficiency was recorded in 20% CC (34.36%) and the lowest in 5% OPF (1.36%). The proximate composition of the harvested fruit-bodies showed lowest moisture content (80.2%) in 5% but highest (86.4%) in 10% CC, at P £ 0.05. The highest ash content was recorded in 10% BG while the highest crude fibre was in 10% CC. Ethanol-soluble sugars had the highest value of 9.62% in 10% SC while the values in other substrates were not significantly different from each other at P £ 0.05. The control without additive had the highest protein content (23.2%), and the lowest value (15.5%) was found in sawdust supplemented with 20% OPF. The lipid content ranged from 1.06% in control to 1.6% in sawdust supplemented with 20% BG. This study has shown that 10% BG and 20% OPF are the best supplement/supplementation levels that enhanced mushroom yield and nutritional contents in A. auricula.

SUMMARY
This abstract investigated the effect of inoculation of Pleurotus tuber-regium, a Nigerian white rot fungus, period of incubation, different levels of contamination on cutting fluids degradation in contaminated soil over 30, 60 and 90 days. Control for different levels of cutting fluids was also used to compare rates of bioremediation of the contaminant in the soil. At the end of each incubation period, the mycelia-ramified substrate was separated from the soil layer and dried. The soil samples were analyzed for physico-chemical parameters; total petroleum hydrocarbon, lignin content by determining the acid detergent fraction (ADF), heavy metals content of the soil using flame atomic absorption spectrophotometer, and changes in the polyphenol oxidase and peroxidase activities were also determined after 1, 2 and 3 months. P. tuber-regium improved the nutrient status of the soil and increased enzyme activity was recorded. A reduction in the pH and heavy metal contents of the soil at all levels of cutting fluids concentrations was detected. The lignin in the rice straw decreased from 34.50% in the control to 8.06% at 30% cutting fluids concentration after 3 months of incubation. The highest TPH loss of 30.84% was recorded at 20% cutting fluids contamination after 3 months compared to 13.75% at the onset of the experiment. The improvement of the nutrient contents of the soil, bioaccumulation of heavy metals, degradation of TPH, lignin, and increased activity of polyphenol oxidase and peroxidase was due to biodegradation of the cutting fluids.

SUMMARY
Objective: To investigate the potential of Pleurotus tuber-regium in the degradation of rattan wood and maize stovers.
Methodology and Results: Twenty five (25g) each of the substrates rattan wood and maize stovers were weighed after the addition of 75ml of distilled water. They were covered with aluminum foil and sterilized at 121oC for 15 minutes. Later they were incubated with two 5mm agar diameter mycelia and incubated at 28 ± 2oC. The controls were not incubated. This was replicated four times and harvested after 30, 60 and 90 days. The proximate composition; percentages of nitrogen, carbon and potassium, pH, loss of organic matter, digestibility and metabolisable energy and in-vitro gas digestibility were carried out on the substrates degraded by P. tuber-regium. In degraded rattan wood, crude protein increased significantly from 1.60% to 5.90% and on maize stovers 2.75% to 8.74%, crude fibre decreased significantly from 44.68% to 20.92% for rattan wood and maize stovers 32.33% to 13.03% after 90 days of incubation. In both substrates ether extract, ash and dry matter contents also decreased but moisture contents increased from 0 – 90 days. Carbon, Nitrogen and Potassium increased significantly as the incubation period increased. The pH decreased with the least value being 4.55. Loss of organic matter of the substrates reduced significantly as the period of incubation increased. There was also significant decrease in loss of water as the incubation period increased, the lowest being 32.25% in rattan wood. There was a reduction in fibre analysis and enzyme production but the organic matter digestibility and metabolisable energy increased with the incubation period. Gas production for in-vitro gas digestibility increased at three hour intervals with highest volume being 29.00ml at 24hours for maize stovers.
Conclusion and Applications of Findings: The results showed that environmental wastes can be recycled and controlled by biodegradation and the product would be of nutritive value in compounding ruminant feeds.
