Abstract

Fermetodege is an innovation of fermented feed with a mixture of water hyacinth, corn cobs, and rice bran which was developed in the manufacture of ruminant feed by utilizing the role of microbes. Fungal communities in the feed fermentation process have a role as microbes that can degrade materials containing cellulose to increase the palatability of feed. This study aims to determine the diversity of cellulolytic fungi isolated from fermetodege, namely ruminant fermented feed mixed of water hyacinth, rice bran, and corn cobs that influence the fermentation process of feed ingredients. Fungi isolation was carried out using potato dextrose agar (PDA) media and screened by growing on carboxymethyl cellulose (CMC). Fungi isolates was analyzed based on Shannon-Wiener to get the diversity and evenness index, and the Simpson dominance index. There were nine cellulolytic fungi isolates with the Shannon-Wiener diversity index value in medium category 1.3423-1.8814 (1<H’<3), the evenness index 0.8340-0.9668, and the Simpson dominance index in the low category (close to 0) namely 0.1608-0.3105. The results showed that the community structure of cellulolytic fungi in the fermetodege had moderate diversity with an even distribution without the dominance of certain species of cellulolytic fungi during fermentation. The diversity of fungi in fermetodege: fermented feed mixture of water hyacinth, rice bran, and corn cobs has a diversity of fungi that have the potential to be used in the fermentation process.
