Description
We evaluated the potentils of pure wild microfungi isolated from decaying
wood in utiizing diesel as source of carbon/energy and monitoring of their
physiological responses via OD and pH gradient flxes. The fungi diversity
was obtained by conventinal enrichment culture methods. Pure cultures of
tentatie fungal species namely: SC1, SC2, SC3, YI and Y2 were tested for
their ability to utiize diesel oil as carbon and energy source. From the cultural, morphological and biochemical characterizatin and comparison with
respect to the standard reference of fungi, the wild microfungi tentatiely
named as SC1, SC2, SC3, YI and Y2 were seemingly the members of Penicillum, Aspergillus, Mucor, Candida and Cryptococcus species. The diesel dependent growth of the pure microfungi was assessed by monitoring the flxes in the pH and Optial density OD of the minimal media slurry for 288
hours. There were flctuatins in OD as well as pH values for the diffrent microfungi. The mean pH data 5.90 ± 0.01-7.01± 0.01 and the OD 0.349±0.001 -1.232 ± 0.002 were obtained. The ability of our fungal isolates to tolerate diesel and grow in it, suggests that the isolates can be employed as
bioremediatin agent.
