The lagoon is a form of semi-enclosed bay which is one type of an estuary. In lagoon water there is a meeting and mixing of freshwater and seawater thus it causes free relationship between the sea and the source of freshwater. The effect of tides that mixed with freshwater will cause a change of the aquatic character instantly. It will certainly affect the diversity of organism species, including bacteria. Some types of bacteria, one of them is Bacillus, it is basically soil bacteria, but commonly found in fresh and brackish waters. The purpose of this study was to determine the characteristics of morphology, colonies and biochemistry of bacteria that isolated from sediments of mosquito breeding lagoon in the coast of Medana village, Tanjung district, North Lombok regency. This research was descriptive observational, used non random purposive sampling with 15 samples. Data collected in the form of types of bacteria found in 15 points from sediments of mosquito breeding lagoon. The data analysis used descriptive analysis. The results of 15 points of lagoon sediments that isolated, from 15 bacteria colonies that was identified as morphological, colonies and biochemical characteristics found three types of bacteria: Aeramonas schubertii, Bacillus subtilis, and Enterbacter agglomerans. The conclusion is the sediments of mosquito breeding lagoon in the coast of Medana Village, Tanjung district, North Lombok regency is obtained the bacteria, for instace: Aeramonas schubertii, Bacillus subtilis, and Enterobacter agglomerans.

Mannose and mannooligosaccharide acted as prebiotic that consumed by probiotic bacteria. Mannanase were the second most important enzymes for the hydrolysis of hemicelluloses, beside xylanase. The objective research was to obtain eminent strains of Bacillus sp. in mannan degradation which can potentially be a probiotic candidate. The study employed a completely randomized design using four concentration levels repeated six times. Halotolerant Bacteria were isolated from mangrove ecosystem at Hanura beach, Teluk Pandan, Pesawaran District in Lampung Province. They are grown on the sea water complete agar media. Mannan degradation isolates were then characterized to determine their character with a variety of tests, including resistance to pH, salt, and metal ions, pathogenicity, and determination of mannanase production duration. Thirty strains are found to grow at 3-6% salt content, and 9 of them have mannanolytic activity. They grow optimally at pH 7-10. Seven isolates were proven to be positively hydrolyzed blood agar in the pathogenicity test. The addition of Iron (III) Chloride increased the enzyme activity by 11.12% in IBK3 isolates at 96 hours of cultivation period which was 0.05 UmL-1. It acted as cofactors of enzymatic reactions. Strains Bacillus sp., were able to degrade mannan substrate. It quantified using Index of mannanolytic. Strain IBK3 has the highest index of mannanolytic activity as much as 10.74. Their ability to grow in salt media indicated that they were halotolerant. They were more likely to live at base rather than acid habitat. Only IBK3 and ID2K1 showed non-pathogenic isolates. Only FeCl 3 addition has proven to rise up enzymatic activity.
