PURPOSE: To enable the hydrolysis of starch and at the same time the economical production of lactic acid by adding an amylose-hydrolyzing saccharifying enzyme into an aqueous nutrient medium containing starch as an assimilable carbon source and fermenting the mixture with microorganism.DEIDEIE SHI...
Lactobacillus delbrueckii mutant Uc-3 utilizes both cellobiose and cellotriose efficiently, converting it into L(+) lactic acid. The enzyme activities of cellobiose and cellotriose utilization were determined for cell extracts, whole cells, and disrupted cells. Aryl-beta-glucosidase activity was detected...
PURPOSE:In production of D-lactic acid by fermentation method wherein a solution having finished D-lactic acid fermentation as a seed mold of the next D-lactic acid fermentation is subjected to D-lactic acid fermentation, to produce high-purity D-lactic acid, by raising the concentration of mu...
Lactic acid and cell production from whey permeate by Lactobacillus rhamnosus with different nutrient supplements were investigated in this study. Yeast ex
lactic acid production. However, higher production costs have hindered the large-scale application of PLA because of the high price of lactic acid. Therefore, reduction of lactic acid production cost through utilization of inexpensive substrates and improvement of lactic acid production and productivity ...
In the last years the production of lactic acid has increased due to growing polymer markets (biodegradable synthetics), elevated demand in the chemical sector (oxygenated chemicals, ecologically friendly solvents) and many applications in the food industry. At present, the annual lactic acid productio...
Lactic acid is widely used in the food, cosmetic, pharmaceutical, and chemical industries and has received increased attention for use as a monomer for the production of biodegradable poly(lactic acid). It can be produced by either biotechnological fermentation or chemical synthesis, but the former...
With 10% (w/v) sugar beet juice (105g total sugar l 1 ), 84g lactic acid l 1 was produced. The optical purities of d -lactic acid from the feedstocks ranged from 97.2 to 98.3%.关键词: d-Lactic acid Lactobacillus delbrueckii Sugar beet juice Sugarcane juice Sugarcane molasses ...
