 Abstract |
: A total of 23 strains of marine photosynthetic bacteria were isolated from samples taken in Satun Province (8); Songkhla Province (3 from the beach, 3 from a seafood processing plant, 6 from a shrimp farm); and the eastern coastal area (2) using GM medium. These were cultivated under anaerobic-light condition (3 klux) at room temperature (30?2๐ C). All of them were found to be halotolerant (6% NaCl) and gramnegative bacteria. The isolated strains were cultured under anaerobic-light and aerobicdark conditions at 37๐ C, and the extracellular ALA determined by colorimetric method. Results indicated that eight strains of photosynthetic bacteria, SSl, SS3, SS4, SH5, FS3, FS4, BK and ES16 produced higher amount of extracellular ALA and will be used for further studies. |
