Growth parameters determined from controlled batch cultures (pH 7.2) of strains F4430/73, F4810/72, F837/76, and PA^a

Parameter	Anaerobic growth				Aerobic growth

Glucose consumption (%)b	100	28	42	35	100	100	100	100

^aCells were grown under N₂-generated anaerobiosis (pO₂ = 0%) and full aerobiosis (pO₂ = 100%). Data are the means of duplicate cultures. For clarity, standard deviations (below 10%) are not shown.

^bFinal biomass and glucose consumption were determined at the end of growth, i.e., 1.5 h after the OD₅₆₀ reached its maximal value.
