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.
