[Study of the composition of the exhaust gases from the manufacture of feed antibiotics and of fungal and bacterial entomopathogenic preparations].

The main composition of exhaust gases in production of various preparation, such as bacitracin, chlortetracycline, hygromycin, entobacterin, dendrobacillin, boverin and kormogrisin was determined by the method of group chemical analysis and gas chromatography. The exhaust gases contaned fatty acids c2--c6, aldehydes and ketones c2--c6, alcohols c2-c5, amines (diethylamine, triethylamine, etc) and some phenols. The level of the substances was insignificant. However, they were toxic for living beings. The exhaust gases had disagreeable odour.
