Abstract

Bacterial isolates from rhizosphere of cassava plant were isolated. The bacterial isolates are resistant to buprofezin. They have the potential to be used as bioremediation agents. The buprofezin-resistant bacteria isolates need to be carried out to determine the morphological, biochemical, Plant Growth Promoting Rhizobacteria (PGPR), molecular, and bioassays characteristics. This study aimed to determine the morphological, biochemical, molecular, PGPR, and bioassay characteristics of KR1 and PA11 isolates. The result showed that KR1 and PA11 were gram-negative and endospore forming bacteria. Biochemical characteristic of KR1 showed positive result for motility and catalase test, glucose fermentation, starch hydrolysis, and MR/VP test, while PA11 showed positive result for glucose, sucrose, and lactose fermentation, starch hydrolysis, MR/VP and oxidase test. KR1 was a fermenter bacteria, while PA11 was an oxidizer/fermenter bacteria based on the O/F test. Molecular characteristics showed KR1 was Bacillus wiedmannii and PA11 was Bacillus cereus. PGPR characteristics showed KR1 was phosphate solubilizing bacteria and PA11 was nitrogen fixing bacteria. Both KR1 and PA11 have ability to produce indole acetic acid (IAA). The bioassay characteristic showed that the consortium application of bacterial isolates (KR1 and PA11 isolates) had a significant effect on the root length of rice plants. The bacterial isolates application showed a better result on plant height than control (without bacterial isolate application).
