The metabolic behaviour in a high NaCl environment of Tetracoccus soyae and Bacillus sp., which were isolated as halotolerant strains, was studied. Two strains were less sensitive to some antibiotics, such as kanamycin B, neomycin B and streptomycin, in the presence of 1 to 2 M NaCl. The insensitivity of these organisms to antibiotics appeared to be caused by their lower ability to take these antibiotics, in the presence of NaCl.In the presence of NaCl (1 to 2 M), two strains assimilated much less carbohydrate than in NaCl free medium.The effect of NaCl on the uptake of L-serine, which is a favorable carbon source for T. soyae, was investigated usign ^14C-labeled L-serine. It appeared that L-serine uptake is prevented by NaCl and its uptake is recovered with L-proline, which is known as a substance reinforcing the halotolerance of T. soyae.
