How canacid production by glucose and lactose fermentation be differented in the same tube?
To differentiate acid production by glucose and lactose fermentation in a test tube one must look at the neck and the butt of the test tube. Different colors indicate fermentation or non-fermentation.
Does citrobacter freundi ferment lactose?
Yes, Citrobacter freundii is capable of fermenting lactose as it possesses the enzyme beta-galactosidase, which enables the breakdown of lactose into fermentable sugars. This fermentation process can be identified through various biochemical tests used in microbiology.
Why milk turning into curd is a chemical change?
The process of milk turning into curd is a chemical change because it involves the fermentation of lactose by bacteria present in the curd culture. This fermentation process causes a change in the chemical composition of the milk, leading to the formation of curd through the breakdown of lactose into lactic acid.
What has a chemical rection with yeasts?
Yeasts undergo fermentation, a chemical reaction that converts sugars into alcohol and carbon dioxide. This process is commonly used in baking and brewing to leaven dough and produce alcoholic beverages.
What indicator is used to determine glucose or lactose in voges proskauer test?
In the Voges-Proskauer test, the indicator used to determine glucose or lactose fermentation is alpha-naphthol and potassium hydroxide (KOH). These reagents react with the acetoin produced during the fermentation process, resulting in a pink or red color change if the organism is positive for acetoin production.
Why do humans undergo fermentation?
Humans do not undergo fermentation, only plants do. Humans undergo through lactate process instead.
Can grape juice undergo fermentation without the presence of yeast?
No, grape juice cannot undergo fermentation without the presence of yeast. Yeast is necessary for the fermentation process to occur, as it converts the sugars in the grape juice into alcohol.
Why isn't a pH indicator needed in the lactose broth fermentation tubes?
A pH indicator is not needed in lactose broth fermentation tubes because the fermentation of lactose by bacteria produces acid as a byproduct, lowering the pH of the broth. This drop in pH can be visually observed as a color change in the medium, indicating lactose fermentation.

Give result lactose test for bacteria citrobacter diversus?
Citrobacter diversus is capable of fermenting lactose, therefore it would test positive for lactose fermentation in biochemical tests. This bacterium produces acid and gas during lactose fermentation, which can be detected using appropriate methods such as the MacConkey agar test.
Can phosphate solubilizing bacteria undergo fermentation?
no
Is sheep cheese lactose free?
All milk has lactose. It is the sugar in milk. During cheese making, the fermentation bacteria that sour the milk are converting the lactose to lactic acid. Despite this fermentation some lactose almost always remains in the cheese. Lactose intolerance varies from person to person. Some cheeses which are dry enough and have very little lactose remaining can be handled by those with milder lactose intolerance.
What are the raw materials of lactic acid fermentation?
The raw materials required for lactic acid fermentation are simple sugars, such as glucose or lactose, and lactic acid bacteria. These bacteria convert the sugars into lactic acid through a process called fermentation.
How is anaerobic respiration in bacteria used in yogurt making?
A fermentation process is used to make yogurt. Milk contains the sugar lactose; and some bacteria will ferment lactose to produce lactic acid. the lactic acid clots the milk protein, and give the yogurt its sour taste. Fermentation is just another name for anaerobic respiration.
Why milk turning into curd is a chemical change?
The process of milk turning into curd is a chemical change because it involves the fermentation of lactose by bacteria present in the curd culture. This fermentation process causes a change in the chemical composition of the milk, leading to the formation of curd through the breakdown of lactose into lactic acid.
A type of bacteria that digest the milk sugar lactose?
Lactobacillus is a type of bacteria that can digest the milk sugar lactose. It produces the enzyme lactase, which breaks down lactose into simpler sugars that can be metabolized. This process is important for the fermentation of dairy products like yogurt.
