ISOLASI DAN IDENTIFIKASI MIKROBA TANAH PENDEGRADASI SELULOSA DAN PEKTIN DARI RHIZOSFER Aquilaria malaccensis

Abstract

Gaharu (agarwood) is one of non-timber forest product. It can be found commonly from trees of genus Aquilaria. Gaharu has been used in religious rituals, as perfume, incense, fragrance, even for medicines. Agarwood formation is caused by microbial infection inside plant tissue host. This research aims to explore soil microbes in rhizosphere of Aquilaria malaccensis which have ability to degrade cellulose and pectin. Screening was conducted to observe cellulase and pectinase activities. In this research, 26 isolates of fungi and 29 isolates of bacteria were isolated. It was found that seven isolates of fungi and six isolates of bacteria showed positive result with clear zone around the cultures. The results of identification showed soil microbes with the highest cellulose and pectin solubilizing index are Bacillus brevis for bacteria and genus Helicoma for fungi.
