Abstract:

This research isolated and identified bacteria with capability of starch, cellulose and protein decomposition from frass of black soldier fly (Hermetia Illucens) larvae (BFL). Dilute suspension of BFL frass was spread on petri dishes with solid Nutrient Agar for bacteria isolation. Selection and evaluation of bacteria with capability of starch, cellulose and protein decomposition was based on their ability of creating halo zone on starch agar, CMC and skim milk media. Identification of selected bacterial isolates was based on 16S rDNA sequences. There were 44 bacterial strains isolated from BS

Background: Disease causing bacteria such as Vibrio alginolyticus, Aeromonas hydrophila, and Pseudomonas aeruginosa present a problem for fish farming. Treatment to remove them are generally carried out using antibiotics which have side effects on fish, the environment and humans. However, the use of antibacterial compounds derived from heterotrophic bacteria serve as a good alternative for antibiotics. Therefore, this study aimed to explore antibacterial activity in the secondary metabolite extracts of heterotrophic bacteria against Vibrio alginolyticus, Aeromonas hydrophila, and Pseudomonas

Abstract Kerosene is a type of hydrocarbon commonly known as paraffin oil which is usually used as a home heating fuel, lamp and asphalt solvent. The presence of kerosene in the asphalt production can potentially cause environmental pollution, one of which affects soil conditions. Some bacteria that have specific ability to degrade hydrocarbon content in soil are called hydrocarbonoclastic bacteria. This study aims to determine the proportion of the presence of bacteria that have the potential to degrade hydrocarbons, in this case kerosene, in polluted soil at the location of one of the larges

Based on the current state of research in the development of biofertilizers, it can be argued that the biocomposition of Bacillus megaterium bacteria will lead to an increase in the availability of a number of macronutrients for pl
