var., accession no. KCTC 0697BP, a salt-resistantvariant isolated from ',' a traditional Korean fermented soy bean paste. Thisvariant produces poly-gamma-glutamic acid (or poly-gamma-glutamate, &#x3b3;-PGA), an edible, soluble, anionic, and biodegradable high molecular-weight polymer.var.produces &#x3b3;-PGA with a higher molecular weight than other extracellular &#x3b3;-PGAs derived from generalsp. strains. Accordingly, the &#x3b3;-PGA produced byvar.can be utilized for the development of high value-added products, such as cosmetics, absorption agents, and biodegradable plastic materials.

[object Object]

The present invention relates to a surface expression vector having pgsBCA, a gene coding poly-gamma-glutamate synthetase and a method for expression of target protein at the surface of microorganism using the vector. The vector, in which foreign genes are inserted, transforms microorganisms and makes foreign proteins expressed stably on the surface of microorganisms.

Salt-resistantvar. chungkookjang, accession no. KCTC 0697BP, separated from 'chungkookjang' a traditional Korean fermented soy bean paste and its poly-gamma-glutamic acid (or poly-gamma-glutamate, g-PGA), an edible, soluble, anionic, and biodegradable high molecular-weight polymer.var. chungkookjang produces g-PGA with a higher molecular weight than other extracellular g-PGAs derived from generalsp. strains and can be utilized for the development of high value-added products, such as cosmetics, absorption agents, and biodegradable plastic materials.
