In this research, a new type of biodegradable film based on the extracellular polymeric substances (EPS) and isolated from thermophilic microalga Graesiella sp., was formulated characterized. The EPS 0.221 mm thick. Atomic force microscopy scanning electron images revealed homogeneous character with lamellar microstructure. displayed yellowish color, high transparency, ultraviolet barrier prope...

Multicellular microbial communities are the predominant form of existence for microorganisms in nature. As one of the most primitive social organisms, Myxococcus xanthus has been an ideal model bacterium for studying intercellular interaction and multicellular organization. Through previous genetic and EM studies, various extracellular appendages and matrix components have been found to be invo...

A huge variety of biopolymers, such as polysaccharides, polyesters, and polyamides, are naturally produced by microorganisms. These range from viscous solutions to plastics and their physical properties are dependent on the composition and molecular weight of the polymer. Exopolymers have been associated with the initial adhesion of microbes which is the primary step for biofilm formation. More...
