We respect their Elders, past, present and future and recognise their continuous connection to Country. The genus contains approximately 250 . Since the phospholipase B (PLB) was reported as a deacylase of both lecithin and lysolecithin yielding fatty acids and glycerophosphocholine (GPC), there was a question as to whether it is a single enzyme or a mixture of a phospholipase A 2 (PLA 2) and a lysophospholipase (LPL).We purified the PLB in Penicillium notatum and showed that it catalyzed deacylation of sn-1 and sn-2 fatty acids of 1 . At Oxford, Florey was known as the ‘bushranger of research’ because he would aggressively chase money for his projects.5 After exhausting all funding opportunities in the United Kingdom, Florey set his sights further afield.
