Enzymes which would be active in cold conditions can be used in a wide range of fields from molecular biology to detergent industry due to their low processing capacity and high activity. In this study, sixty cold-adapted bacteria were isolated from water and sludge samples collected from Erzurum and Van provinces. Identification of eight isolates by molecular [(GTG) 5 -PCR and 16S rRNA sequencing] techniques and tests for temperature (4-35°C), pH (3-11) and salt (2-15% (w/v) requirements were performed. These bacteria were belonging to Pseudomonas chlororaphis subsp. aureofaciens (SM 01 1 A ), Psychrobacter faecalis (SM 01 2 D ), Rahnella aquatilis (SM 01 5 A ), Shewanella putrefaciens (SM 01 8 A ), Pseudomonas lactis (SM 01 10 A ), Flavobacterium chryseum (SM 01 12 E ), Exiguobacterium mexicanum (SM 01 17 A ) and Glutamicibacter arilaitensis (SM 01 18 A). The physicochemical requirements for all isolates ranged between 4-25°C, pH 5-7 and 2-15% salt (NaCl) concentration. However, E. mexicanum did not require salt in growth medium. All bacteria were evaluated for protease, lipase and amylase enzymes and all were found to be multiple enzyme producers. The eight isolates were identified from the resources of Turkey, for the first time and enzyme production abilities of some isolates to produce enzymes were declared. The originating of the producers of these enzymes from Turkey shows that Turkey has a remarkable reservoir for cold-adaptive microorganisms and these microorganisms will make important contributions to the detergent industry worldwide.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
