Abstract

Shrimp waste is a perishable material. The degradation process is carried out by decaying microbes by producing degrading enzymes. The presence of chitin content in shrimp waste causes the emergence of chitinase enzyme-producing bacteria. Chitin is a linear homopolymer composed of N-acetyl-D-glucosamine monomers with -(1,4) glycosidic bonds. Chitin has unique properties, namely; biodegradable, biocompatible and non-toxic. This causes chitin and its derivatives to be widely used in various industrial and biomedical applications so that chitin and its derivatives have great economic value. There were 10 isolates of chitinolytic bacteria from shrimp waste with varying morphological characteristics. The ten bacterial isolates were NR02, NR03, NR04, NR05, NR06, NR07, NR08, NR09, NR10, NR11 and PU01. Chitinolytic index CI value > 2 was produced by 4 bacterial isolates, namely; NR02, NR07, NR09 and PU01. The lowest IK value was generated by NR08 with a value of 0.01. The chitinolytic bacteria obtained have different characters and it is very likely that they come from different types

Abstract

Basil is a plant that can be used as a traditional medicine. One part of the basil plant used as an alternative medicine is the leaves. Basil leaves contain active compounds, including flavonoids, saponins, tanins, and essensial oils. These active compounds is able to prevent the presence of pathogenic bacteria that can accelerate food spoilage, so that basil leaves can be used as an alternative natural preservative. The objective of the study was to determine the ability of basil leaves as a natural preservative for  mackerel. The research was carried out in vitro, by observing the physical, chemical, and microbiological characteristicts of mackerel which were treated 8 hours of soaking basil leaf extract. Variations in the concentration of basil leaves used were 0, 25, 50, 75 and 100%. The results showed that the physical quality of the 8-hour storage samples showed changes in the physical quality of the fish, as seen from the color, eyes, gills, mucus, aroma and texture. The microbioloical quality of fish was analyzed by the total plate number method. The total number of bacteria decreased as the concentration of basil leaf extract increased
