Abstract

The adaptational changes in cellular fatty acids and morphology of γ-Proteobacteria belonging to different genera ; Vibrio, Halomonas, Pseudoalteromonas ; isolated from northern Adriatic waters and cultured in four media (Marine Broth, R2 Broth and tenfold dilutions of both) was investigated. The bacterial strains with identical 16S rRNA sequences isolated from different waters used different- mechanisms or -extent of the same mechanism to adapt their growth in equal culture media. In contrast, a similar growth strategy in each of used cultures was employed by different strains isolated from the same water body. Divergence in nutrient quality and requirement in cultures from that presented in bacteria natural environment induced important changes in cellular fatty acids (i) unsaturation, (ii) cis to trans isomerisation, (iii) chain elongation (iv) branching and/or morphology (Winnie-the-Pooh effect) or even cell division blocking. The results strongly suggest that growth and appropriate cellular response of bacteria in culture is predetermined by nutritional conditions in their genuine environment and can be useful for interpretation of trophic differences between proximate environments.
