Abstract

AbstractTwenty seven strains of lactic acid bacteria (LAB) were isolated from bakasang, Indonesian traditional fermented fish product. In general, LAB have inhibitory activity againts pathogenic bacteria and spoilage bacteria. Screening for antimicrobia activity of isolates were performed with well-diffusion method. One isolate that was designed as Pediococcus BksC24 was the strongest against bacteria pathogenic and spoilage bacteria. This strain was further identified by 16S rRNA gen sequence comparison. Isolates LAB producing antimicrobial agents from bakasang were identified as Pediococcus acidilactici.Keywords : Bakasang, LAB, antimicrobial, phenotypic characteristics, 16S rRNA gene

Abstract

ABSTRACT. Research has been carried out to determine the content of the bacterium escherichia coli in well water dug in the sub-district of Lirung, regency of the Talaud Islands. Water is one of the sources of living needs of living things, humans, animals and plants. Well water is a means of clean water from the soil for daily use, such as drinking water, cooking, washing and bathing. Therefore, the water must be pollution-free and meet the quality requirements for clean water. e.coli bacteria are bacteria that generally live in the intestines of humans and animals. This research uses a quantitative descriptive method. The results showed that 9 samples of water wells taken from 3 sites in the Lirung sub-district, in the regency of the Talaud Islands, contained e.coli bacteria which exceeded the maximum threshold not in accordance with the regulations of the Ministry of Health RI No.  416 / MENKES / PER / IX / 1990   Keywords: Bacteria Escherichia coli, Dug Well Water.
