ABSTRACT: Cyanobacterial extracellular polymeric substances (EPS) are mainly composed of high-molecular mass heteropolysaccharides with variable composition and roles according to the microorganism and environmental conditions. The number of constituents - both saccharidic and non-saccharidic - and complexity of structures give rise to speculations on how intricate their biosynthetic pathways could be, and how many genes may be involved in their production. However, little is known regarding the cyanobacterial EPS biosynthetic pathways and regulating factors. This review organizes available information on cyanobacterial EPS, including their composition, function and factors affecting their synthesis, and from the in silico analysis of available cyanobacterial genome sequences, a putative mechanism for their biosynthesis is proposed

Abstract

ABSTRACT: Cyanobacterial extracellular polymeric substances (EPS) are mainly composed of high-molecular mass heteropolysaccharides with variable composition and roles according to the microorganism and environmental conditions. The number of constituents - both saccharidic and non-saccharidic - and complexity of structures give rise to speculations on how intricate their biosynthetic pathways could be, and how many genes may be involved in their production. However, little is known regarding the cyanobacterial EPS biosynthetic pathways and regulating factors. This review organizes available information on cyanobacterial EPS, including their composition, function and factors affecting their synthesis, and from the in silico analysis of available cyanobacterial genome sequences, a putative mechanism for their biosynthesis is proposed
