SummaryThe effect of arginine on the production of extracellular lipase byPseudomonas fluorescens32A was studied. Arginine repressed lipase production when N was supplied partially or totally as arginine. Proteinase production was unaffected under the same conditions. Arginine did not repress lipase secretion when cells were pregrown in an arginine-containing medium; however, repression was found with uninduced cells. Several arginine-analogues were tested for the ability to repress lipase secretion and. of these, L-homoarginine and L-canavanine were the most effective. D-Arginine, L-arginine methyl ester, and L-ornithine did not cause repression. With the exception of glutamic acid and methionine, those amino acids that supplied N but not C for growth were found to repress lipase secretion. It is suggested that the accumulation of metabolic intermediate(s) may cause repression of lipase production.

Studies were carried out on the ability of Talaromyces emersonii Stolk to produce extracellular lipase in stationary liquid medium under various conditions. The best temperatures for lipase synthesis and activity were 40–45 °C, and at all the temperatures (37–55 °C) tested for lipase production, maximum enzyme was produced 8 days after incubation. Lipase synthesis was induced when various carbohydrates were used as carbon sources both in the presence and absence of yeast extract. The significance of lipase production in relation to the natural habitat is discussed.
