Rapid adaptation of Rhodococcus erythropolis cells to salt stress by synthesizing polyunsaturated fatty acids
Appl Microbiol Biotechnol 2014 Jun;98(12):5599-606.PMID:24599310DOI:10.1007/s00253-014-5549-2.
Bacterial cells are known to adapt to challenging environmental conditions such as osmotic stress. However, most of the work done in this field describes the adaptation of growing populations where the new generations acquire traits that improve their ability to survive. In the present study, the responses of Rhodococcus erythropolis cells within the first 30 min after exposure to osmotic stress caused by sodium chloride were studied. The cells changed the total lipid fatty acid composition and also the net surface charge in the 30 min following exposure. Surprisingly, the cells produced a high percentage of polyunsaturated fatty acids. In the presence of 7.5 % NaCl, these polyunsaturated fatty acids, mainly eicosapentaenoic acid (C20:5ω3), arachidonic acid (C20:4ω6) and Docosapentaenoic Acid (C22:5ω3), comprise more than 36 % of the total fatty acids. The possible function of these very uncommon fatty acids in bacteria could be the decrease in the number of negatively charged groups in ion channels resulting in a repellence of the NaCl.
Effect of culture conditions on growth, lipid content, and fatty acid composition of Aurantiochytrium mangrovei strain BL10
AMB Express 2012 Aug 10;2(1):42.PMID:22883641DOI:10.1186/2191-0855-2-42.
This study explored the influence of various culture conditions on the biomass, lipid content, production of docosahexaenoic acid (DHA), and fatty acid composition of Aurantiochytrium mangrovei strain BL10. The variables examined in this study include the species and concentration of salt, the concentrations of the two substrates glucose and yeast extract, the level of dissolved oxygen, the cerulenin treatment, and the stages of BL10 growth. Our results demonstrate that BL10 culture produces maximum biomass when salinity levels are between 0.2 and 3.0%. Decreasing salinity to 0.1% resulted in a considerable decrease in the biomass, lipid content, DHA production, and DHA to palmitic acid (PA) (DHA/PA) ratio, signifying deterioration in the quality of the oil produced. The addition of 0.9% sodium sulfate to replenish salinity from 0.1% to 1.0% successfully recovered biomass, lipid content and DHA production levels; however, this also led to a decrease in DHA/PA ratio. An increase in oxygen and cerulenin levels resulted in a concomitant decrease in the DHA to Docosapentaenoic Acid (DPA) (DHA/DPA) ratio in BL10 oil. Furthermore, the DHA/DPA and DHA/PA ratios varied considerably before and after the termination of cell division, which occurred around the 24 hour mark. These results could serve as a foundation for elucidating the biochemistry underlying the accumulation of lipids, and a definition of the extrinsic (environmental or nutritional) and intrinsic (cell growth stage) factors that influence lipid quality and the production of DHA by BL10.
Endogenously synthesized (-)-proto-quercitol and glycine betaine are principal compatible solutes of Schizochytrium sp. strain S8 (ATCC 20889) and three new isolates of phylogenetically related thraustochytrids
Appl Environ Microbiol 2007 Sep;73(18):5848-56.PMID:17660311DOI:10.1128/AEM.00610-07.
We report that endogenously synthesized (-)-proto-quercitol (1D-1,3,4/2,5-cyclohexanepentol) and glycine betaine were the principal compatible solutes of Schizochytrium sp. strain S8 (ATCC 20889) and three new osmotolerant isolates of thraustochytrids (strains T65, T66, and T67). The compatible solutes were identified and quantified by use of nuclear magnetic resonance spectroscopy, and their identity was confirmed by mass spectroscopy and measurement of the specific optical rotation. The cellular content of compatible solutes increased with increasing NaCl concentration of a defined medium. (-)-proto-Quercitol was the dominating solute at all NaCl concentrations tested (0.25 to 1.0 M), e.g., cells of S8 and T66 stressed with 1.0 M NaCl accumulated about 500 micromol (-)-proto-quercitol and 100 micromol glycine betaine per g dry weight. To our knowledge, (-)-proto-quercitol has previously been found only in eucalyptus. The 18S rRNA gene sequences of the four (-)-proto-quercitol-producing strains showed 99% identity, and they displayed the same fatty acid profile. The only polyunsaturated fatty acids accumulated were docosahexaenoic acid (78%) and Docosapentaenoic Acid (22%). A less osmotolerant isolate (strain T29), which was closely phylogenetically related to Thraustochytrium aureum (ATCC 34304), did not contain (-)-proto-quercitol or glycine betaine. Thus, the level of osmotolerance and the osmolyte systems vary among thraustochytrids.
