Vannamei shrimp (Litopenaeus vannamei) is a fishery commodity widely cultivated in various parts of Indonesia. The main problem often found in vannamei shrimp production is poor water quality during the rearing period. This study aims to isolate and identify E. coli contained in water, sediment, and meat of vannamei shrimp cultivated in shrimp ponds and examine its sensitivity to antibiotics. The research was conducted from March to May 2023 at the Technical Implementation Unit (UPT) Vannamei Shrimp Ponds of the Maritime Affairs and Fisheries Service, Tanjung Punak Village, Rupat Utara District, Bengkalis Regency, Riau. The survey method was used in this study. The Most Probable Number (MPN) method was employed for E. coli isolation to calculate bacterial density, and the Kirby-Bauer method was used to test bacterial sensitivity to antibiotics. Based on the identification of the six isolates carried out, it was found that only two isolates were positively identified as E. coli bacteria, namely SD C 3.1 and IP B 1.1, which were isolated from sediment and the Wastewater Treatment Plant (WWTP) pond. The diameter of the inhibition zone for sediment isolate RF01 against the antibiotic chloramphenicol was 18.75 mm, indicating intermediate sensitivity. On the other hand, WWTP isolates RF02 exhibited an inhibition zone of 17 mm for chloramphenicol, indicating medium sensitivity as well. However, it showed resistance to penicillin with a diameter of 6.5 mm and resistance to ampicillin with a diameter of 2 mm.

Microplastics are widespread environmental pollutants detected in aquatic, terrestrial, and atmospheric ecosystems. Their persistence, coupled with their potential to bioaccumulate and release toxic additives, raised serious concerns for both environmental and human health. This study aimed to assess microbial biodegradation as a viable strategy for reducing microplastic pollution. The research focused on the mechanisms through which microorganisms, particularly bacteria and fungi, degraded plastic polymers under various environmental conditions. Several microbial strains demonstrated the ability to degrade polymers such as polyethylene, polystyrene, and polyvinyl chloride, albeit at varying efficiencies. Environmental parameters such as temperature, pH, oxygen availability, and nutrient concentration, were found to significantly influence the rate and extent of microbial degradation. Despite these promising findings, the overall degradation rates observed in natural environments remained low. Moreover, challenges related to microbial specificity, metabolic limitations, and the scalability of degradation processes hindered the practical application of microbial treatments on a large scale. The complexity of polymer structures and the additives used in plastic manufacturing further complicated microbial breakdown. To overcome these barriers, future research should prioritize genetic engineering of microbial strains and the optimization of bioprocesses to improve degradation efficiency. Such advancements could pave the way for sustainable and effective biotechnological solutions to mitigate microplastic pollution.

Mangrove ecosystem is a coastal wetland has biodiversities such as flora, fauna, and microorganisms. Microorganisms are an importants component in the mangrove ecosystem and have many roles, including source the nutrition, decomposer, and a source of biotechnology products. Cellulolytic bacteria are a group of cellulase-producing bacteria capable of breaking down cellulose into glucose monomers. This study aims to screen and determine the diversity of cellulolytic bacteria from the mangrove ecosystem. The research method has been experimental by exploring the cellulolytic bacteria in soil and sediment from the mangrove ecosystem. Three sampling locations were selected such as the litter soil, soil in the root, and soil in the tidal area. The screened of potential bacteria-producing cellulase was obtained by bacteria growth on Carboxy Methyl Cellulose (CMC) agar medium. The isolates were cultured for 48 hours at 37°C. Then, the bacteria that produced the cellulolytic activity were characterized by morphological and physiological characteristics. The results were adjusted according to Bergey's Manual of Determinative Bacteriology. The determination showed that six isolates had the same characteristics as Bacillus, Cellulomonas, Lactobacillus, and Micrococcus. The cellulolytic activity index showed that three isolates were sequentially MS06 (9,73), MS03 (6,30), and MS08 (5,41).

This study aims to analyze the effect of storage temperature on microbial growth in several pro coffee variants and to investigate the impact of storage temperature on the quality of pro coffee containing B. cereus SN7. The coffee variants used were original, latte, original jelly, and latte jelly at temperatures of 10, 25, and 37°C for 7 days of storage. Microbial growth was observed using the total plate count method, while the pro coffee quality was analysed using the organoleptic test. The results showed that low storage temperatures can inhibit microbial growth and maintain the quality of pro coffee. The lowest total number of microbes was found in the original variant with a storage temperature of 10°C, with a value of 0.11 × 103 CFU/mL, and the highest total number of microbes was found in the latte jelly variant with a storage temperature of 25°C, with a value of 3.476 × 103 CFU/mL. In the organoleptic test, the highest value was found in the latte variant coffee at a storage temperature of 10°C, categorized as 'very like', with a value of 35% for taste, 30% for aroma, and 30% for colour. The effect of temperature on the product quality of several probiotic coffee variants containing B. cereus SN7 showed a significant difference (p < 0.05) in microbial growth and the quality value of the probiotic coffee. Statistical analysis showed the effect of temperature on the product quality of several pro coffee variants containing B. cereus SN7.
