Abstract

Microbes live in nature freely in water, air, or soil. One type of microbe is fungi. Fungi are microorganisms that are able to degrade fiber. This study aims to isolate fungi from corn waste and test the degradation ability of the best corn waste fungi fiber as a fibrous feed bioactivator. This research was carried out at the Laboratory of Animal Production, Faculty of Agriculture, Animal Husbandry Study Program, University of North Sumatra, in March 2018 - June 2018. This study used corn waste (corn cobs, corn straw, corn husk, corn flowers and corn roots). Parameters observed were macroscopic morphology (colony size, colony shape, clony color, colony elevation, colony edge), microscopic morphology (form of hyphae, conidial shape, and conidiophoric surface) and the ability to degrade fiber in fungi. Conclusions from the results of research on corn waste exploration obtained 6 fungi isolates, 4 of which were cellulolytic fungi that were able to degrade fibrous feed, namely two strains of Aspergillus sp., Fusarium sp., And Rizoctonia sp. Isolates which have a potential to degrade fiber are JE isolates (Rizoctonia sp. fungi) with a cellulolytic index of 1,178.

Highlights

Fungi / fungi are berspora plants that are non-chlorophyll organisms, so that fungi cannot provide their own food by photosynthesis as in plants with chlorophyll Suriawiria [1]
According to Yunilas et al [3], indigenous microorganisms are microbes originating from their own substrate which have optimal ability to degrade fibrous feed
2.3 Research Methods The research method used is an exploratory method which begins with the creation of indigenous microorganism sources (MOI) adopting the making of local microorganisms (MOL)

Summary

Introduction

Fungi / fungi are berspora plants that are non-chlorophyll organisms, so that fungi cannot provide their own food by photosynthesis as in plants with chlorophyll Suriawiria [1]. According to Sudirman and Imran [2] the waste of corn plants has a high crude fiber content of ± 28%. This results in low digestibility of feed. According to Yunilas et al [3], indigenous microorganisms are microbes originating from their own substrate which have optimal ability to degrade fibrous feed. Fungi are microorganisms that are able to degrade fiber, but not all types of fungi function to degrade fiber (cellulose), so it is suspected that there are cellulolytic fungi in the corn waste. An enzyme activity test is needed to see the ability of fungi to degrade fiber by calculating the cellulolytic index. In order to obtain the best degradation from the fungi originating from corn which has the potential to degrade fiber
