The series Section D, Research, offers interesting if extremely patchy coverage of Pollock's research work. There is a significant group of notes and data on research on bacterial toxins from 1941 to 1945, and some material relating to work on the 'genocycles' in the early 1950s, penicillinase in the 1960s and bacterial genetics in the early 1970s. The section also has an extensive collection of Pollock's notes on the literature, most of which appear to date from the 1960s, and a little material 1972-1973 relating to a consultancy with the Japanese company Kyowa Hakko Kogyo Co. Ltd for which he was asked to give an expert opinion on the production of L-lysine by fermentation. Further documentation on Pollock's work on bacterial toxins and penicillinase may be found in section L, Correspondence, which includes many letters in which Pollock reports on work in progress.
