Abstract

This invention relates to a biological process for the biosynthesis of two intracellular solutes identified as di-mannosyl-di-myo-inositol phosphates and 1,3'-di-myo- inositol phosphate. These have been identified in the hypothermophilic bacteria Thermatoga maritima and Thermatoga neapolitana (growth Topt 80 degree C) during growth at supraoptimal temperatures in complex medium. The environmental conditions necessary for their accumulation in high concentrations indicate that these new compatible solutes can have an effect in protecting macromolecules (specifically biocatalysts) and cells against operations involving heating, drying or freezing. Di-mannosyl-di-myo-inositol phosphate and 1,3'-di-myo- inositol phosphate can be used in enzyme catalysed processes at high temperatures or when these are performed in the presence of chemical denaturing agents such as detergents, organic solvents, oxidizing agents or caotropic agents such as urea or guanidine chloride with the intention of stabilizing their activity over the short and long term. Di-mannosyl-di-myo-inositol phosphate and 1,3'-di-myo- inositol phosphate can also be used to stabilize liposomes and other membrane systems used in the microencapsulation of drugs and other compounds used in the pharmaceutical, cosmetics, detergents and other industries. <IMAGE> Di-mannosyl-di-myo-inositol phosphate and 1,3'-di-myo- inositol phosphate can also be used during the drying of proteins and whole cells for transport and prolonged conservation and also as adjuvants for the preservation of microorganism strains or animal and plant cell lines, as well as perfused organs by freeze-drying or at low temperatures.
