Abstract

Estuaries are waters that are dominated by mangroves and are influenced by fluctuations in salinity. One of the organisms that live in these waters is the nipah worm (Namalycastis rhodochorde). Fluctuations in salinity affect the growth of bacteria associated in the intestines of nipah worms (N. rhodochorde). The purpose of this study was to determine the character of Bacillus bacteria that live in the intestines of nipah worms (N. rhodochorde). To identify NrLtF5 isolate bacteria, follow Bergey's manual determinative of bacteriology which includes gram staining, catalase production activity test, sporulation test, gelatinase test, methyl red test, cytochrome oxidase test, oxidative fermentative assay, motility activity test, ornithine activity, decarboxylase and indole production, acid and gas formation test, citrate test, urease test, and determination of the optimum temperature for bacterial growth. The results confirmed that the bacteria with the isolate code NrLtF5 had similar characters with the genus Bacillus with gram-positive staining, bacilli-shaped, endospore, and produced the enzyme catalase.
