A composition useful for protecting and/or repairing DNA from oxidative damages said composition comprising redistilled cow's urine distillate (RCUD) having components benzoic acid, and hexanoic acid, with ammonia content of the composition ranging between 5-15 mg/L, and optionally along with anti-oxidants; and a method of protecting and/or repairing DNA from oxidative damages using composition of claim, said method comprising steps of estimating the amount of folded DNA in a sample, mixing the said composition to the said DNA either before or after the exposure of the DNA to the oxidatively DNA-damaging agent, and determining percentage folded DNA in the mixture showing protection and/or repair of DNA from oxidative damages.

Composition (RCUD) for protecting and/or repairing DNA from oxidative damages and a method thereof

The present invention relates to a novel strain of the yeast Saccharomyces cerevisiae having accession number MTCC Y0022B211 (=NCYC 2647), which is useful for the preparation of ethanol by the fermentation of sugars. The invention also encompasses a process for the preparation of this strain of yeast, which process comprises: (a) growing a diploid strain of S. cerevisiae designated MTCC Y0001 (=NCYC 2646) in a known medium, sporulating the strain, treating the sporulated cells with a lytic enzyme to liberate the spores, collecting the liberated spores; (b) growing a haploid strain of S. cerevisiae designated MTCC Y0002 (=ATTC 90506); (c) mixing the spores obtained in step (a) with the cells obtained in step (b), incubating the resultant spore-cell mixture at a temperature in the range of 15.degree. C. to 37.degree. C. for a period of 1 to 10 days; (d) spreading the incubated spore-cell mixture on a non-medium, and incubating the mixture at a temperature in the range of 15.degree. to 37.degree. C. for a period of 1 to 10 days; and (e) collecting the cells produced in step (d); and spreading on a selective medium so as to eliminate the spores and cells of steps (a) and (b) and allowing only hybrid cells/cytoductants to grow.
