摘要
极端嗜盐菌大量存在于天然高盐域——海水晒盐场及盐湖或盐碱湖中。它们生长要求很高浓度的 NaCl(至少为12%),最适生长浓度为20—25%,甚至在饱和的 NaCl 中也能生长。
Biochemical characteristics of eight stra-ins grown in high saltern media were exa-mined.The optimal salt concentrations forall of their growth condition were 18—25%.All of their pigments shown that the absor-ption peaks for strains F1,F2,F4,F5A andF6 were at 388,492 and 527 nm in the ab-sorption spectra and no pigments in the cell ofstrains F7,F8 and F9.The cell walls ofthe bacteria have no diaminopimelic acid(DAP)too.Glycerol diether moieties werepresent in the lipids of strains F1,F2,F4,F5A,F6 and F8 only,but absent in F7 andF9.According to their characteristics,weidentified strains F1,F2,F4,F5A,F6 andF8 as halophiles and F7 and F9 as halotole-rants.
