Biographical entry Shew, D. I.



D. I. Shew worked for the Kraft Walker Cheese Company Pty Ltd. He showed that one form of vat failure during cheese making resulted form the presence of bacteria producing an antimicrobial substance, now know as "nisin". His work led in 1940 to the first isolated starter room in Australia and phage free cultures and in 1946 he introduced New Zealand methods, including starter rotation, for overcoming phage infection in the factory.
