To reduce nutrient cost for lactic acid production, spent cells, a by-product in fermentation processes, were used as a nutrient source and the treatments of spent cells were investigated in this study.
Untreated spent cells did not show significant effect on lactic acid production.
After acid-hydrolysis, spent cells gave an increase in productivity to some extent, but the low glucose consumption indicated a nutrient limitation.
The nutrient limitation was overcome easily by supplementing a small amount of yeast extract (YE).
The combination of 5 g/L YE and the spent cell hydrolyzate (SCH) had high performance in lactic acid production relative to 15 g/L YE.
Moreover, two kind of acid-hydrolysis methods, diluted acid based hydrolysis and concentrated acid based hydrolysis, were also compared.
The diluted acid based hydrolysis had the advantages over the concentrated acid based one in lactic acid production due to its less nutrient destruction and lower salt inhibition.
When diluted acid based SCH was supplemented, YE supplementation could be cut down to 20% with no significant decrease in productivity and yield.

∙ 11y agoWhen muscle cells cannot get the oxygen they need for cellular respiration, they use the process of fermentation to get energy. So basically muscle cells.
Add your answer:
Earn +20 pts
When there is no oxygen for your cells the cells use this to get energy?
lactic acid fermentation. (produces lactate and is only about 100th as efficient as cellular respiration)
What is the use of lactic acid fermentation in the kitchen?
Hot Dilly beans are an example of lactic acid fermentation.
Explain why muscles must use lactic acid fermentation instead of cellular respiration during intense physical activity?
Because mammalian muscle cells are genetically programmed to perform lactic acid fermentation, not ethanol fermentation.
Which organism uses lactic acid fermentation to release energy from glucose and produces this lactic acid in the process?
lactic acid is what gives our yogurt we eat the recognizable taste feature alsp organisms use lactic acid to release energy from glucose to produce
List the two type of fermentation and tell where each take place?
The two types of fermentation are alcoholic fermentation, and lactic-acid fermentation. Alcoholic fermentation, occurs in yeast and other single celled organisms. Lactic-acid fermentation occurs in muscle cells. Your muscles use it to create energy when there is not enough oxygen to use for normal respiration.
How does swimming use lactic acid?
After a while of swimming, your muscles use lactic acid. It uses it through Lactic acid fermentation. It results in more energy.
When there is no oxygen for your cells the cells use this to get energy?
lactic acid fermentation. (produces lactate and is only about 100th as efficient as cellular respiration)
Do your body cells always use cellular respiration and fermentation?
Yes. Cell respiration and lactic acid fermentation.
What is a use of lactic acid in the kitchen?
Hot Dilly beans are an example of lactic acid fermentation.
What is the use of lactic acid fermentation in the kitchen?
Hot Dilly beans are an example of lactic acid fermentation.
How much ATP does lactic acid fermentation produce?
The production of lactic acid is an anaerobic process. This type of reaction do not involve the use of oxygen.
What sport use the lactic acid system?
Swimming, running, and basketball use the lactic acid system.

Why do sports such as swimming and running use the lactic acid system?
Lactic acid is produced when muscles in the body move at high rates and over long periods of time. So, even with swimming, you move your arms and legs a lot to gain speed, and this causes the acid to form. In reality, this acid is another type of acid, however it combines with oxygen to form Lactic Acid.
