| Abstract: | Summary Lactic acid was produced by viable Lactobacillus delbreuckii NRRL-B445 in a hollow fiber fermenter. Final cell densities in the fluid surrounding the fibers in the fermenter were apparently as high as 480 gms DW/L, and volumetric productivities reached 100 gms/L-hr lactic acid. The observed cell yields were appreciably lower than batch cell yields. |
