Abstract

This research focuses on using chemical simulation methods to determine the Total Fungi available in a water environment. The water type investigated was the fresh and salt water environment. Total Heterotrophic Fungi (THF) were Aspergillus niger, Aspergillus flavus, mucor sp, penicillium sp, Aspergillus sp, lomentospora sp, Fusarium sp, collecttrichum sp, cladosporium sp, Trichoderma sp and Rhizopus sp for both fresh water and salt water environment. The effect of the fungi on the investigated water environment was monitored with relation to differences in temperature and time as well as the growth rate of the Total fungi. The research work reveals that increase in temperature influence the THB and THF growth rate characteristics of some of the microorganisms from 0.5 × 103 cfug-1 to 43 × 103 cfug-1 fresh water medium, 30 × 10-1 for salt water medium. Growth rate of fungi and their effect on temperature were investigated and detail result of the total heterotrophic fungi growth mode and the rate of degradation were also examined for TFF 15, TFF 30, TFF 45, TFF 60, TFF 75, TFF 90, TFF 105 and TFF 120. The results were subjected into model graphs which was discussed and analyzed using Matlab ODE 45. The MATLAB ODE 45 Computer Programme was used in the evaluation of functional coefficients of heat generated by microbes and substrate, effect of temperature on specific rate growth of fungi in the various water environment under investigation.
