Maximum specific growth rate, biomass concentration and extracellular lipase, hyaluronate lyase and phosphatase activities were determined. All three species were capable of growth at 100% air saturation but at reduced growth rates. The presence of oxygen altered the production of extracellular enzymes. Propionibacterium avidum was the best adapted for growth in aerobic environments., UL https://www.microbiologyresearch.org/content/journal/micro/10.1099/00221287-129-11-3327
