Abstract
The Nitzschia cf. thermaloides was found in reservoirs of mud volcanoes in eastern Crimea. It was determined that this species has wide spectrum of halotolerance; in particular, it is capable of vegetative reproduction within the range of 0–110 ‰ salinity of the substrate. For the first time, the effect of salinity on the fatty acid composition of the microalga Nitzschia cf. thermaloides was studied. Regardless of salinity, the quantitative and qualitative content of fatty acids did not change, which indicates the ability to maintain a stable compacted membrane structure, which probably partly determines the adaptation of this species to salinity. The composition of fatty acids is mainly represented by saturated fatty acids, which allows us to consider this species as a potentially “useful” object for biotechnology as a source of saturated fatty acids or an alternative raw material for biofuel.
