FUNGI CHARACTERIZATION OF DIGESTATE

ABSTRACT

This research work was carried out to evaluate the presence of fungi on fungi cattle rumen derived digestate. Seven (7) sample of liquid-solid digestate were collected for analysis from Owina laboratory in university of Benin, Benin-city, Edo State. Serial dilution was carried out to enumerate the population of fungi in the digestate test tube containing potatoes dextrose agar (PDA) and streak using wire loop. Each plate was inoculated at 37℃ for 72 hours. The mean total fungi count ranged from 0.5× 107 cfu/mil to 4.0×107 cfu/ml. The fungi isolated from the digestate sample includes: Aspergillus niger, Aspergillus flavus, Trichoderma sp, Penicillium citrinum, Penicillium chrysogenum, Sepedonium sp, Syncephalastrum racemosum, and Trichoderma sp had the highest percentage distribution (70%) among the seven (7) isolates while Penicillium citrinum had the lowest percentage distribution (32.5% ). These fungal isolated were discovered to be healthty for both soil and the digestate sample when compared with other researchers when in moderate population, with conducive environment. To maintain and sustain the quality of a good digestate, environmental hygiene, and good storage facility should be practiced for both agricultural users and other required sectors.
