the production and fermentation of biological substances is from seed fermentation to production of lactic acid,In this case, the yeast is used in a low pH growth environment, a yeast family, which is specially used for lactate dehydrogenase (LDH) activity, or a substitute, whose activity is ...
Sensitivity analysis showed that the prices of lactic acid, lactide and poly(lactic acid) were the largest determinants of the profitability in the plant while the sale of by-products (animal feed) was also critical to the plant's economics. This work has cast insights on the techno-economic...
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...
The invention relates to a procedure for the preparation of D-(-)-lactic acid in which a strain of Lactobacillus bulgaricus capable of converting lactose into D-(-)-lactic acid to an extent of more than 50 %, is cultivated in a medium containing lactose or a hydrolysis product thereof. It...
A process for the lactic acid fermentation of fruit products is disclosed wherein an initial product in the form of a mash or juice having a pH of less than 3.7 is pasteurized and thereafter subjected
the present invention relates to a process for the production of optically pure d - or l - lactic acid by fermentation of an aqueous nutrient soft nitrogen, vitamins, amino acidssugar and trace elements includes using a microorganism at ph 4 and 6, which is characterized by that the test me...
Most attention has been given to bacteriocins of lactic acid-producing bacterium (LAB) due to their GRAS (generally recognized as safe) status and probiotic characteristic, whereby their application in industry has been immensely reviewed (Sandiford 2017; McAuliffe et al. 2001). For instance, bacte...

In this work, highly porous biodegradable poly(lactic acid) (PLA) foams with bi-modal architecture were prepared by using the melt-compounding process in a... Bahrami, Pedram,Abbasi, Danial,Matin, Ali,... - Journal of Polymers and the Environment 被引量: 0 加载更多站...
(or pyruvic acid) and two molecules of ATP. The pyruvate enters into thetricarboxylic acid cycleif enoughoxygenis present or is fermented intolactic acidorethanolif not. Thus, glycolysis produces both ATP for cellular energy requirements and building blocks forsynthesisof other cellular products.See...
