The invention relates to mutant strains of the genuswhich 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&#xb0; C. to about 70&#xb0; 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.

Mutant bacterial strains of the genus sphingomonas deficient in production of polyhydroxybutyrate and a process of clarification of sphingans and compositions thereof

[object Object]

The invention relates to mutant strains of the genuswhich 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 PUB-deficient Sphingan solution, to a clarification temperature of about 30&#xb0; C. to about 70&#xb0; 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.

The invention relates to high performance gellan gum compositions having a 0.1% curdmeter gel strength of at least about 117 g/cm, i.e. from about 117 g/cmto about 400 g/cm. The high performance gellan gums have a low acyl content but an increased molecular weight. One embodiment of the invention also relates to processes for producing high performance gellan gums having high clarity. The invention further relates to food and non-food industrial products comprising high performance gellan gums.
