Abstract
|
|
|
|
In this study, we isolated about 70 bacterial strains from terrestrial and marine environments in Jeju island, and finally, total 21 strains were obtained based on the 16S ribosomal RNA gene sequence analysis. These isolated strains were classified into 16 genera of 5 classes and were identified as an unrecorded species in the Republic of Korea. As a result of the substrate utilization and capability for polymer degradation, the physiological phenotypes for acid resistance and halophilic bacteria were observed to be distinct from each other, except for some acid resistance strains. This study might provide basic information on utilization for indigenous microorganisms.
