By using a medium containing an ingredient for activating brewer's yeast, a brewer's yeast cell body is immersed in the medium in the presence of an added inorganic salt; and the immersion is stirred at a predetermined temperature to concurrently carry out an aerobic activation treatment, resulting in the formation of a brewer's yeast cell body containing a high ribonucleic acid content comprising 10% by weight or more of ribonucleic acid based on the weight of the cell body.

Solid fermentation-promoting substance and method for preparation thereof

The present invention has for its object to provide a method for obtaining a barley malt oil abundantly containing ceramide derivatives of plant origin which is highly safe and gives a good image as a material in an efficient, simple and easy manner as well as to provide a barley malt oil which is obtained by such method above and is enriched in highly safe ceramide derivatives. The present invention provides a method for producing barley malt oil containing ceramide derivatives, comprising the steps of: dipping spent grains obtained in a process of beer production in a polar organic solvent as a dipping solution, separating an extract liquid from the dipping solution, and concentrating the extract liquid and also provides a barley malt oil containing ceramide derivatives obtainable by dipping spent grains obtained in a process of beer production in a polar organic solvent, separating an extract liquid from the resulting solution, and concentrating the extract liquid.

Process for producing yeast extract

A polysaccharide RON substance which has antitumor activity can be produced by fermenting sucrose with a synthetase. The synthetase can be isolated from Leuconostoc strains. Preferred strains of the microorganism are Leuconostoc mesenteroides FERM BP-2242, 2711, 2712, 2713, 2714, and 2670. The substance exhibits antitumor activity against syngenic tumor Meth A, a transplantable tumor in mice.

Process for producing polysaccharide ron substance with a synthetase

A method is provided for preparing an antitumor dextran by contacting a culture broth containing sucrose with an antitumor dextran obtained from Lactobacillus confusus and collecting the antitumor dextran from the culture broth. The enzyme can be used as a crude enzyme solution or may be further purified by conventional means. The Lactobacillus confusus is preferably one of the following: 40-1 strain (FERM BP-2865) , 40-3 strain (FERM BP-2866) , 77-1 strain (FERM BP-2867), 78-1 strain (FERM BP-2868) or 80-1 strain (FERM BP-2869).

Method for preparing an antitumor dextran using a dextran synthetase

Lactobacillus confusus strains capable of producing a dextran which has biological activities such as an excellent antitumor activity, etc. are disclosed. Also disclosed is a method for producing said dextran using said microorganism or dextran synthetase prepared by said microorganism.
