This research aims to identify the type of mold found on corn from pig manure fermentation tanks with the capacity to digest corn. Collected from pig manure fermentation tanks, cultured in a solid PDA when studying the morphology can be identified in the genus assumed to be a fungal genus Aspergillus sp. Genetic diversity analysis of the Internal Transcribed Spacer (ITS) regions of ribosomal DNA (rDNA).
extracting DNA using a modified method of Meniatis et al., (1982). The DNA has to do to increase the amount of DNA in a section of the Internal Transcribed Spacer region by Polymerase Chain Reaction (PCR) with the pair of universal primers ITS3 and ITS4. It was found that DNA sequences of fungus has a size of about 300 bp. The results from this research will guide the study to identify the types of fungus that can degrade the corn cob. As well as guidelines for its use in accelerating the degradation of agricultural residues such as rice, sugarcane, etc., to other species.
