Isolation and characterization of lipase-producing thermophilic bacilli from geothermal springs in Armenia and Nagorno-Karabakh

Аннотация

Nine morphologically distinct lipase producing thermophilic aerobic endospore-forming bacteria were isolated from geothermal springs distributed on the territory of Armenia and Nagorno Karabakh. The phenotypic characteristics of the isolates were studied using standard methods. The list of methods include isolation, enrichment and screening for lipase activity, studies of morphological and physiological characteristics of the isolates, phylogenetic studies, software analysis and reconstruction of the phylogenetic tree. The optimal temperature values of studied isolates varied from 55°C-65°C.
