Viabilitas dan Kemampuan Bakteri Kitinolitik Bacillus Sp. Bk17 dalam Formulasi Tablet untuk Mengurangi Layu Fusarium pada Benih Cabai Merah (Capsicum annuum L.)

Abstract

Chitinolytic bacteria Bacillus sp. BK17 has been known to inhibit the growth of Fusarium oxysporum on chili seeds. Bacterial cell viability is an important factor in using the cell for biological control. This study was aimed to evaluate viability of chitinolytic bacteria Bacillus sp. BK17 and its potential in tablet formulation as a biological control against F. oxysporum. Viability of Bacillus sp. BK17 cell was reduced in 40 days of storage. Bacillus sp. BK17 in tablet formulation was able to control Fusarium wilt on chili seeds by 63,65% of 0 day stored and 28,57% by 15 days stored, respectively. In addition, Bacillus sp. BK17 in tablet formulation increased height and biomass on chili seeds.
