Pengujian Beberapa Metode Isolasi Mikroorganisme Rimpang Jahe

Abstract

testing of different isolation method of microorganisms from ginger rhizomes.Common method of isolation of pathogenic fungi from the rhizome of ginger is direct isolation planting. However, a modification is some time needed to find pathogenic and saphrophytic fungi in the rhizome. Nine midified methods of isolation were tested in the isolation of fungi from the rhizome of ginger collected from market and field, by using PDA medium. It was showed that by wasting diseased rhizomes, more species of fungi were isolated and the isolates grew more rapidly Particullarly storage fungi from rhizomes collected from market. Species of fungi were found in this study such as Cephalosporium sp., Trichoderma sp., Penicillium sp., Mucor sp., Aspergillus flavus, Aspergillus sp., Chalaropsis sp., Gliocladium sp., Rhizopus sp., Gloeosporium sp., Fusarium oxysporum, F. moniliformae, F. equiseti, Fusarium sp.
