  • Process for producing the enzyme cholesterol esterase and for hydrolyzing cholesterol esters of fatty acids by using the enzyme itself
    Patent number: 4387163
    Abstract: The enzyme cholesterol esterase is produced by cultivating a strain of the Achromobacter delicatulus type, isolated from vegetable debris and identified by the symbol NRRL B-12115. Under the described culture conditions, the enzyme is exocellular and therefore does not require extraction from the cells.In addition, the micro-organism has a duplication time less than that of moulds and Actinomycetes. Cholesterol esters of fatty acids can be hydrolysed by adding them to the culture medium before inoculating the strain.
