Leses customary sources can be substituted for sacharidic sources of carbon which are usualy applied to the production of penicillin. The article informes of these substitutions and also of a treatment of nitrogen sources from plants before a sterilization of fermentation medium. Lactose of less purity or dried sweet whey can be substituted for slowly assimilable lactose. Fructose syrup, cane sugar, unrefined cane and beet sugar, unprocessed glucose or ethanol can be substituted for fast assimilable sucrose. Nitrogen sources from plants can be eluated by water at higher pH to reach high yields of penicillin.
