Microorganisms and bioprocesses are provided that convert gaseous C1 containing substrates, such as syngas, producer gas, and renewable H.sub.2 combined with CO.sub.2, into nutritional and other useful bioproducts.

The present invention provides a method for extracting lipids from microorganisms without using organic solvent as an extraction solvent. In particular, the present invention provides a method for extracting lipids from microorganisms by lysing cells and removing water soluble compound and/or materials by washing the lysed cell mixtures with aqueous washing solutions until a substantially non-emulsified lipid is obtained.

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.

The present invention relates to polynucleotides encoding novel fusion polypeptides essentially composed of a signal peptide for membrane translocation and a polypeptide providing -1,6-glucosidase activity and to bacteria containing said polynucleotides. The invention further relates to methods for producing fine chemicals using media containing isomaltose and/or panose as carbon source.
