Abstract

Investigations were carried out on mycological and physiochemical features of soil that is being contaminated with effluents from palm oil mill in Anyigba. Soil samples were taken out of four different locations and were analysed for total fungal count and soil physiochemical parameters for fourteen (14) days. The fungal count range from 8.0 x106 to 1.0x107 cfu/g for palm oil mill effluent polluted soil (POME) (also known as effluents from palm oil mill (EFPOM)) and 2.0x104 and 3.0x104 cfu/g for free soil which served as the control (ofs). The pH, organic matter% as well as organic carbon%, nitrate, moisture contents% alongside phosphorus (ppm) analysed were found to be more in effluent contaminated soil (ECS) compared to the No-oil soil (NOS). Higher fungal count was recorded in the POME polluted soil when compared with oil free soil. The fungi isolated from the EPS were Aspergilus species, Fusarium species, Penicillium species, Geotrichum species, Trichoderma species and yeast. This work shows that the physico-chemical properties of soil contaminated with effluents from palm oil mill were altered by the effluents. The pH, organic matter, organic carbon, nitrate, moisture content and phosphorus content were more in ECS compared to NOS. This work shows further that the fungal counts in ECS was higher than NOS. This implies that fungi strive well in effluents from palm oil mill (EFPOM) and could efficiently use (EFPOM) as its food substrate. Therefore, fungi could be employed as a means of biodegrading and bioremediating soil contaminated with effluents from palm oil mill.
