Isolasi dan Identifikasi Bakteri Halofilik Ikan Talang (Chorinemus sp.) dari Aia Bangih Pasaman Barat

Abstract

Halophilic bacteria is microorganism that live in high salinity environments up to 30%. The bacteria can be found in foods preserved by salting like salted fish. Salted fish is preserved foods are processed by salting and drying. The bacteria that live and ruin salted fish are halophilic bacteria and heterotoleran bacteria like halobacterium, micrococcus, bacillus, pediococcus, peseudomonas and vibrio. This observation aims to determine type of halophilic bacteria found in talang fish. This is descriptif observation held january up to february 2015 is microbiology laboratory FMIPA UNP and balai veteriner laboratory Bukittinggi. Research methods is cup statterplot methods. Sample is talang fis from Aia Bangih, west pasaman. Based on observation found isolate halophilic bacteria. Its belong to gram positve like coccus. From both, the isolates not capable produce endosopra. Talang fish from Aia Bangih, west pasaman contain two isolate halophilic bacteria consist of a genus and two species.

The Isolation of Staphylococcus Epidermidis Bacteria in White Snapper Salted Fish (Lates Calcalifer) of Sibolga City, North Sumatera Province

“…The pungent odor is caused by the release of certain chemicals produced by spoilage bacteria such as NH3 and cadaverine. Stages of damage occur because the protein produces NH3 and H2S with the help of peptides, free amino acids and vitamins, causing a specific odor discharge (Fifendy et al, 2017). Damage to processed fish products can be seen from the formation of brownish red or yellow spots on the surface of the fish's body and the presence of mucus (Marpaung, 2015).…”

“…Damage to processed fish products can be seen from the formation of brownish red or yellow spots on the surface of the fish's body and the presence of mucus (Marpaung, 2015). The bacteria that can survive in an atmosphere that has a high salt content are called halophilic bacteria, a group of bacteria that are included in halophilic bacteria (Fifendy et al, 2017).…”

Isolation, Characterization and Activity Test of Soil Origin Bacteria Amilage

“…A study was conducted to obtain potential isolates for amylase-producing sources from the soil to fulfill the industrial need for enzymes (Purnawan et al, 2016;Remijawa et al, 2020). Previous research studied amylase activation (Susilawati et al, 2015), amylase from shrimp paste (Oktavia et al, 2018), and amylase from water sources (Fifendy et al, 2015). However, research on the isolation of amylase from soil has not been studied before.…”
