being particularly valuable objects of studies. Methanotrophs are Gram-negative bacteria, which use methane as the main source of carbon and energy in their life cycle. These belong to the Proteobacteria family and are classed as methylotrophs [27, 32, 33].
The main characteristic feature of methanotrophs is the ability to oxidise methane to methanol. This reaction is catalysed by a specific methane-monooxygenase (MMO) enzyme. Monooxygenase oxidises methane to methanol, and the role of MMO in this

methanotrophic microorganisms. Current literature reports concern mainly halotolerant methanotrophs, i.e.: Methylomicrobium alcaliphilum 20Z, M. kenyense, M. buryatense [23, 50, 51]. Reshetnikov together with colleagues distinguished two types of gene organisation responsible for the synthesis of ectoine related to the tolerance of microorganisms to the salinity and the production of this osmolyte. Methylomicrobium marinus 7C and M. kenyense AMO1 strains have ectABC genes and accumulate ectoine in the amount
