Ingredient selection for plastic composite supports for L-(+)-lactic acid biofilm fermentation by Lactobacillus casei subsp. rhamnosus
Article Abstract:
The ingredient selection for plastic composite supports (PCSs) for L-(+)-lactic acid biofilm fermentation by Lacto bacillus casei subsp. rhamnosus was examined. The research utilized two half sets of a five factorial design to evaluate the effects of various agricultural components on the properties of plastic supports. Results show that highest biofilm population, cell density and lactic concentration were found in PCS with soybean hulls, yeast extract, soybean flour, mineral salts and bovine albumin. PCS was also discovered to supply complex nutrients for the growth of L. casei.

Lactic acid production in a mixed-culture biofilm reactor
Article Abstract:
An evaluation of the novel solid supports for pure and mixed culture in continuous lactic acid fermentations in biofilm reactors is discussed. Streptomyces viridosporous and Lactobacillus casei subsp. rhamnosus were used as the biofilm and the lactic acid producers, respectively. The pure polypropylene chips-containing reactor, the suspension culture containing reactor and the various pp chip containing biofilm reactor were compared as high-performance liquid chromatography determined lactic acid production. Mixedcultures yielded higher lactic acid rates compared to pure-cultures.

Nutrient leaching and end product accumulation in plastic composite supports for L-(+)-lactic acid biofilm fermentation
Article Abstract:
Nutrient leaching and product accumulation in plastic composite supports (PCS) for L-(+)-lactic acid biofilm fermentation were investigated. The research analyzed leachates from PCS and polypropylene discs using the micro-kjeldahl method. Results reveal that the accumulation in plastic composite supports was a result of absorption and had no effect on lactic acid production or biofilm formation.
