Biotechnological Production of Lactic Acid and Its Recent Applications
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 route has received considerable interest recently, due to environmental concerns and the limited ...
متن کاملlactic acid production with in situ extraction in membrane bioreactor
background and objective: lactic acid is widely used in the food, chemical and pharmaceutical industries. the major problems associated with lactic acid production are substrate and end-product inhibition, and by-product formation. membrane technology represents one of the most effective processes for lactic acid production. the aim of this work is to increase cell density and lactic acid produ...
متن کاملL(+) lactic acid production and separation from dairy wastes(whey):in situe separation of lactic acid using lon-exchange resins in automatic control of PH.
Whey with a large amount of BOD(50000 PPM) is a dangerous environmental pollutant.this important source of lavtose(4-5%) is A USEFULL SUBSTRATE FOR A RANGE of fermentation processes.lacitic acid with swvwral applications in industries is one of these products.Specially L(+) isomer of this acid worthing 10 times as much as the mixture of L&D,is used in medical purposes such as absorbable surgica...
متن کاملProduction of L(+) Lactic Acid using Lactobacillus casei from Whey
The aim of this work was to study the fermentation of whey for the production of L(+) lactic acid using Lactobacillus casei. The effect of different process parameters such as pH of the medium, temperature, inoculum size, age of inoculum, agitation and incubation time was monitored to enhance the lactose conversion in whey to L(+) lactic acid. Fermentations were performed without any pH control...
متن کاملDisposable bioreactors: from process development to production
Single-use bioreactors are commonly used for seeding stainless steel bioreactors or for producing material. The profitability of these equipments has been well demonstrated on more that decade. But few data on its scalability have been published. In 2010-2011, Merck Serono Biodevelopment performed a study in order to evaluate the performance of several disposable bioreactors. As different techn...
