摘要： The present invention relates to a novel bacterial strain designated DD1, which has the ability to produce organic acids, in particular succinic acid (SA), which was originally isolated from bovine rumen, and is capable of utilizing glycerol as a carbon source; and variant strains derived there from retaining said capability; as well as to methods of producing organic acids, in particular succinic acid by making use of said microorganism.

摘要： The present invention relates to a method for degrading DNA in a sample obtained by microbial fermentation or biotransformation, comprising treating the sample with a combination of increased temperature and low pH. It also relates to a method for releasing DNA from a microbial cell, comprising incubating the microbial cell at a temperature of 45° C. to 55° C. for two to ten hours. Finally, the present invention provides a method for producing a product, comprising a step of releasing DNA from a microbial cell and degrading said DNA.
