Abstract

Plastic waste is the biggest problem that is happening in Indonesia. Plastic waste has resistance and the nature of Persiden. Increased production and low recovery rates cause accumulation of plastic flakes in waters called microplastic. Microplastic has the potential to be swallowed by aquatic biota that can cause internal bleeding and blockage of the digestive tract. Hue microplastic will affect humans who consume them. One of the aquatic biota that is often contaminated by microplastic is fish. Research related to microplastic contamination in the digestive tract of fish has often been carried out. This study examines the level of microplastic contamination in the digestive tract of fish in Indonesian waters refers to the available literature. The results showed that there were 5 types of microplastics contaminated in the digestive tract of fish in Indonesia, namely fiber, film/filament, fragments, pellets, rows, foam and granules.

Abstract

Background: The anting-anting plant (Acalypha indica L.) is used in herbal medicine in the treatment of various diseases. The leaf extract of this plant is known for its antimicrobial activity, but the antimicrobial properties of the endophytic bacteria within its leaves have never been reported. This research aims to determine the antimicrobial activity of endophytic bacteria from the leaves of the anting-anting plant. Materials and methods: The isolation of endophytic bacteria was performed using the spread plate method on nutrient agar (NA) media. Following isolation, the bacterial isolates were characterized through macroscopic and microscopic examination, as well as biochemical tests, which included indole production, hydrogen sulfide (H2S) production, motility, Simmons citrate utilization, methyl red-Voges-Proskauer (MR-VP) test, catalase test, and triple sugar iron agar (TSIA) test. Identification of the bacterial isolates was conducted according to Bergey's Manual of Systematic Bacteriology. Additionally, the antimicrobial activity of the isolates was assessed using the diffusion methodResults: Fourteen isolates of anting-anting leaf endophytic bacteria were obtained (coded as BEDA 1 to BEDA 14). The BEDA 5 isolate exhibited the largest inhibitory zone diameter against Staphylococcus aureus (31.48 mm), while BEDA 9 showed a significant inhibitory zone diameter against Candida albicans (17.84 mm). Conclusion: The two isolates (BEDA 5 and BEDA 9) exhibited significant antimicrobial activity, indicating their potential as promising candidates for alternative antimicrobial agents. These results suggest that endophytic bacteria from Acalypha indica may play an essential role in combating antibiotic resistance and in the development of new therapeutic strategies.Keywords: endophytic bacteria, characterization, antimicrobial activity, Acalypha indica
