Abstract

"The production of lysine by a microbial method was studied. Brevibacterium lactofermentum (ATCC 21086) was used to accumulate lysine. T1\ese experiments were done in shake flasks and a 7.5-liter fermentor.

Lysine and residual glucose were determined at fixed intervals of time during each run. Cell counts were also made for some experiments. Temperature and pH were kept constant during the runs and dissolved oxygen was recorded continuously.

The effects of casamino acid, soy peptone, certain amino acids, glucose and agitation on the rate of production and the yield were studied. It appears that reducing any one of the variables will cause appreciable decreases in the lysine production rates and yields.

Plots of rate and d (log lysine)/dt were made to find the relationship between the rate of lysine production and other factors. Plotting d (log lysine)/dt versus lysine, ignoring initial points appears to be the most suitable method of comparing production rates but further refinements and some relationships with dissolved oxygen are needed" - Abstract, p. ii
