The structure of microbial mats from the Mramornaya Bay (Crimea) was investigated. Light microscopy in combination with transmission and scanning electron microscopy revealed the base of bacterial mats to be interwoven thin filaments (100 to 500 nm in diameter) consisting mainly of sulfur. Numerous bean-shaped single microbial cells (~1.6 × 0.7 µm), some of which were attached to sulfur filaments, were also revealed. High-throughput sequencing of the 16S rRNA genes revealed predominance of bacte
