Title:
A bacteria variant of poly hydroxybutyric acid production deficiency Sphingomonas Genus , and the clear-ized method of Sphingan
Document Type and Number:
Japanese Patent JP6067051
Kind Code:
B2
Abstract:
The invention relates to mutant strains of the genus Sphingomonas which have a mutation in at least one gene encoding a protein involved in polyhydroxybutyrate (“PHB”) synthesis that allows the mutant strains to produce PHB-deficient Sphingans. The invention is also directed to a process for preparing a clarified Sphingan solution comprising heating aqueous Sphingan solution, in particular PHB-deficient Sphingan solution, to a clarification temperature of about 30° C. to about 70° C., and treating the solution with a clarification agent and enzymes. In addition, the invention is directed to a food or industrial product comprising a PHB-deficient and/or clarified Sphingan. One particular embodiment of the invention is directed to a clarified, PHB-deficient high-acyl gellan and the processes of making thereof.
