Abstract

The main problem addressed is the increasing resistance of S. aureus, making it necessary to discover new bio-based antibacterial sources. This study aimed to isolate and identify endophytic bacteria from the leaves of B. hispida originating from Southeast Sulawesi, and to evaluate their antibacterial and antibiofilm activities against S. aureus using the disc diffusion method and crystal violet assay. The research methods included surface and internal tissue sterilization of the plant, isolation of bacterial colonies, Gram staining, metabolite extraction, bioactivity tests, and phytochemical assays. Results indicated one endophytic bacterial isolate with Gram-positive characteristics, and the endophyte extract demonstrated very strong antibacterial activity at a concentration of 200 microgram/mL (inhibition zone 22–23 mm, comparable to the positive control). The percentages of growth inhibition and biofilm degradation reached >80% and >70% respectively at the highest concentration. In conclusion, endophytic bacteria from B. hispida of Southeast Sulawesi have promising potential as a natural source of antibacterial and antibiofilm agents relevant for therapeutic development against S. aureus infections.

Abstract

Rice as the main staple food in Indonesia has a relatively high glycemic index, which may increase the risk of metabolic disorders. Rice engineering through the retrogradation process is one approach that can be applied to reduce its glycemic index. This study aimed to evaluate the effectiveness of post-cooking freezing in engineering rice starch retrogradation to promote resistant starch formation and reduce glycemic digestibility. Freezing was conducted stepwise for 24, 48, and 72 hours. Retrogradation was analyzed through amylose absorbance measurement, while digestibility was evaluated by in vitro starch hydrolysis with glucose determination using a colorimetric method based on 3,5-dinitrosalicylic acid (DNS). The results showed that post-cooking freezing was able to reduce starch digestibility through the formation of retrograded structures. The hydrolysis index of all samples ranged from 2.79 to 4.60%, and the predicted glycemic index was in the range of 41.24–42.25, which falls into the low category. The pattern of digestibility changes showed an increasing trend at 24 and 48 hours of freezing, followed by a decrease at 72 hours. This digestibility profile formed a U-shaped pattern, which may be attributed to the dynamic nature of the retrogradation process during freezing. Keywords: functional rice, resistant starch, predicted glycemic index, starch hydrolysis, in vitro
