  abstract = {{T}he effect of the concentration of a mixture (1/1 (wt/wt)) of yeast extract and bio{T}rypcase ({YE}+b{T}) on the growth and physiology of a new species, #{B}acillus thermoamylovorans$, a moderately thermophilic, non-spore-forming, lactic-acid producing bacterium isolated from palm wine, was studied. {A}t an initial glucose concentration of 100m{M}, #{B}. thermoamylovorans$ growth was limited when the concentration of {YE}+b{T} was lower than 5.0 g/l ; under these conditions, cellular yield reached a maximum value of 0.4 g of cells per g of {YE}+b{T}. {G}rowth limitation due to deficiency in growth factors led to a significant shift in glucose metabolism towards lactate production. {L}actate constituted 27.5 and 76% of the end products of glucose fermentation in media containing {YE}+b{T} at 20.0 and 1.0 g/l, respectively. {T}his result markedly differed from published data for lactic bacteria, wich indicated that fermentative metabolism remained homolactic regardless of the concentration of {YE}. {O}ur results showed that the ratio between cellular synthesis and energy production increased with the concentration of {YE}+b{T} in the culture medium. {T}hey indicate that the industrial production of lactic acid through glucose fermentation by #{B}. thermoamylovorans$ can be optimized by using a medium where glucose is present in excess and the organic additives are limiting.
