چکیده انگلیسی
In this study, physiological processes were analysed, which are involved in salt acclimation of two Stenotrophomonas species, Stenotrophomonas maltophilia strain DSM 50170 and Stenotrophomonas rhizophila strain DSM 14405. S. maltophilia accumulated trehalose as the only osmolyte, whereas S. rhizophila produced additionally to trehalose glucosylglycerol (GG). The different spectrum and amounts of compatible solutes in these two strains led to differences in terms of their salt tolerance. The human-associated S. maltophilia was able to grow in media containing up to 3% NaCl (w/v). In contrast, S. rhizophila propagated in salinities up to 5% NaCl (w/v). The strain was isolated from the rhizosphere, a microenvironment which is characterised by high and changing salinities. Light microscopic analysis of S. rhizophila cells showed a significant increase in cell length of salt-treated cells in comparison to control cells. Cells of S. rhizophila exposed to more than 2% NaCl excreted GG into the medium during the transition from exponential to stationary growth phase, while the internal trehalose pool remained constant. This feature offers a high potential for the biotechnological production of GG.
