Solutions formed by combining poly(&#x3b1;(1&#x2192;3) glucan) with CSin aqueous alkali metal hydroxide solution have been shown to produce the xanthated form of the poly(&#x3b1;(1&#x2192;3) glucan). The solutions so formed have been shown to be useful for solution spinning into fiber of poly(&#x3b1;(1&#x2192;3) glucan) when the spun fiber is coagulated in an acidic coagulation bath. The fibers so produced exhibit desirable physical properties. The poly(&#x3b1;(1&#x2192;3) glucan) employed was synthesized by fermentation.

Composition for preparing polysaccharide fibers

This invention pertains to a novel processing for preparing fibers from poly(&#x3b1;(1&#x2192;3)glucan). The fibers prepared according to the invention, have 'cotton-like' properties, are useful in textile applications, and can be produced as continuous filaments on a year-round basis. The process comprises solution spinning a 5-20% solids concentration of poly(&#x3b1;(1&#x2192;3)glucan) in an aqueous alkali metal hydroxide, in particular NaOH at concentration of 2 to 10 weight-%, and coagulating the spun fiber in an acid coagulation liquid.

The process comprises solution spinning from a novel solution of poly(&#x3b1;(1&#x2192;3) glucan) in a mixture of water and N-methylmorpholine-N-oxide followed by coagulation in a liquid coagulant that comprises a liquid that is not water.

A process for enzymatic preparation of poly (&#x3b1;1, 3 glucan) from sucrose is disclosed. The glucosyltransferase enzyme (gtfJ) fromis used to convert sucrose to fructose and poly (&#x3b1;1, 3 glucan). Application of semi-permeable membranes to continuously remove fructose, a by-product of the gtf enzyme, thus increasing the poly (&#x3b1;1, 3 glucan) liter, is disclosed.

High titer production of poly (&#x3b1; 1,3 glucan)

Solutions formed by combining poly(&#x3b1;(1&#x2192;3) glucan) with CSin aqueous alkali metal hydroxide solution have been shown to produce the xanthated form of the poly(+(1&#x2192;3) glucan). The solutions so formed have been shown to be useful for solution spinning into fiber of poly(&#x3b1;(1&#x2192;3) glucan) when the spun fiber is coagulated in an acidic coagulation bath.

A process for enzymatic preparation of a highly linear poly(&#x3b1;1,3 glucan) from sucrose is disclosed. The glucosyltransferase enzyme (gtfJ) fromis used to convert sucrose to a highly linear poly(&#x3b1;1,3 glucan) in high titers. Hydrolyzed poly(&#x3b1;1,3 glucan) is used as the primer for the gtfJ enzyme reaction resulting in the formation of highly linear poly(&#x3b1;1,3 glucan).
