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.
What else can I help you with?
Which organism uses lactic acid fermentation to release energy from glucose and produces this lactic acid in the process?
Lactic acid fermentation is used by certain bacteria and fungi, but the most common example is in muscle cells in animals. During intense exercise when oxygen is limited, muscle cells switch to lactic acid fermentation to continue producing energy from glucose.
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.
What type of fermentation which results from strenuous exercise when cells use up all their oxygen is called?
The type of fermentation that occurs during strenuous exercise when cells exhaust their oxygen supply is called lactic acid fermentation. In this process, glucose is converted into lactic acid and ATP, enabling energy production despite the lack of oxygen. This is commonly experienced in muscles during intense physical activity, leading to fatigue and soreness.
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.

What human muscles cells use lactic acid frmenation to?
Human muscle cells use lactic acid fermentation primarily during intense exercise when oxygen levels are low. This process allows for the rapid production of ATP, the energy currency of the cell, by converting glucose into lactic acid. While this enables sustained muscle contraction during short bursts of activity, the accumulation of lactic acid can lead to muscle fatigue. Ultimately, lactic acid can be converted back to glucose in the liver once oxygen levels are restored.
How do human muscle cells use lactic acid fermentation to produce energy during intense physical activity?
During intense physical activity, human muscle cells use lactic acid fermentation to produce energy when there is not enough oxygen available. This process converts glucose into lactic acid, releasing energy that can be used by the muscles for short bursts of activity.
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)
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 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.
What sport use the lactic acid system?
Swimming, running, and basketball use the lactic acid system.
What happens when we use the oxygen in our cells faster than it can be replaced?
When oxygen in cells is used faster than it can be replenished, the cells switch to anaerobic metabolism, producing lactic acid as a byproduct. This can lead to a buildup of lactic acid, causing muscle fatigue and eventually leading to muscle cramps or soreness. If severe, it can result in a condition known as lactic acidosis.
