A New Bacillus licheniformis Mutant Strain Producing Serine Protease Efficient for Hvdrolvqis of Sov Meal Proteins.

Induced mutagenesis with y-irradiation of the industrial strain Bacillus licheniformis-60 VKM B-2366,D was used to obtain a new highly active producer of an extracellular serine protease, Bacillus licheni- formis7 145. Samples of dry.concentrated preparations of serine protease produced by the original and mutant strains were obtained, and identity of their protein composition was'established.

[Effect of extrusion on the retention of amino acids and the nutritional value of the protein].

The data of the literature on the impact factors of the extrusion cooking on physical and chemical properties of food proteins, biological value and digestibility have been discussed. Extrusion cooking is a high temperature short-time process, characterizing by a minimal loss of nutrients. and biologically active substances compared to other methods of heat treatment of food.

[Experimental study of mixed infection by Vibrio cholerae and Salmonella typhi].

Mixed infection caused by V.cholerae and S.typhi was studied on guinea pig gall-bladder, used as an experimental model.

[Intraoperative monitoring of a neuromuscular conduction blockade].

Preliminary results of intraoperative monitoring of the degree of neuromuscular blockade using a portable device based on the technique of evoked electromyography are presented. The device has an analogue outlet for the connection with a computer. The technique used is simple and reliable and makes it possible to work out a computerized system for automatic graded supply of current myorelaxants on a feedback principle.
