Dilution rates were chosen to allow the bacteria to grow at the same relative growth rates as compared to their respective μmax values. The steady-state levels and production rates of biomass and extracellular enzymes were determined. The lipase and hyaluronate lyase of P. granulosum and the proteolytic activity of P. acnes and P. avidum were growth linked enzymes (i.e. they were produced at constant amounts per unit of biomass). In contrast, the lipase, hyaluronate lyase and acid phosphatase of P. acnes and the lipase of P. avidum were shown to be non-growth linked enzymes., UL https://www.microbiologyresearch.org/content/journal/micro/10.1099/00221287-131-7-1619
