FIELD: biotechnology, amino acids.
SUBSTANCE: method for preparing taurine involves milling a biological raw, its treatment and isolation of taurine. Waste from meat-processing industry is used as a raw and treatment is carried out with sodium hydroxide solution. Prepared solution is treated successively with protosubtilin, homogenized mass of cattle pancreas or liver. Isolation of taurine from hydrolyzate is carried out by sorption on anion-exchange resin AB-17-2 followed by precipitation of product with 10-fold hydromodulus of ethyl alcohol and the following purification. Method provides increasing yield of taurine in using inedible raw.
EFFECT: improved preparing method, increased yield.
