Is Bacillus subtilis positive for lactose fermentation?
No, Bacillus subtilis is not capable of fermenting lactose as it lacks the enzymes required for lactose metabolism. It is able to utilize other carbohydrates such as glucose and maltose for energy production.
What are the biochemical tests for identification of bacillus subtilis?
The Kirby-Bauer antibiotic test is a general test that determines if an organism is resistant or susceptible to different antibiotics. Many different types of antibiotics can be used but some of the common ones are penicillin, tetracycline, chloramphenicol, and streptomycin.
What are the test results of MR VP for b cereus?
Staph gives both MR and VP positive. MR is used to detect acid production and VP for alkaline or neutral products. Staph first converts into acidic products and has ability to convert those acidic products into some neutral/basic products side by side. Hence it gives both positive results.
What are the two types of fermentation and their equations?
The two types of fermentation are alcoholic fermentation, which produces alcohol and carbon dioxide, and lactic acid fermentation, which produces lactic acid. The equation for alcoholic fermentation is: Glucose → 2 ethanol + 2 carbon dioxide The equation for lactic acid fermentation is: Glucose → 2 lactic acid.
The breakdown of organic compounds such as glucose in the absence of oxygen is called fermentation. The byproducts of fermentation differ from cellular respiration. Which of the following is a chem?
Chemical equation for fermentation is: Glucose → Ethanol + Carbon dioxide + Energy
Is Bacillus subtilis positive for lactose fermentation?
No, Bacillus subtilis is not capable of fermenting lactose as it lacks the enzymes required for lactose metabolism. It is able to utilize other carbohydrates such as glucose and maltose for energy production.
Does Bacillus subtilis grow in MacConkey broth?
Bacillus subtilis is grown on nutrient agar or in nutrient broth. The preferred medium is M9 with glucose.
Which bacteria is amylase positive catalase positive cysteine desulhydrase negative nitrate reduction negative glucose positive lactose positive sucrose positive citrate positive?
bacillus subtilis
Does B subtilis hydrolyze starch?
Yes, Bacillus subtilis has the capability to hydrolyze starch due to the production of amylase enzymes. Amylases secreted by B. subtilis break down starch into simpler sugars such as maltose and glucose that can be utilized by the bacterium for growth and metabolism.
Will glucose give a positive fermentation test?
Yes, glucose typically gives a positive fermentation test. In microbiology, certain bacteria can ferment glucose, producing acids and gases as byproducts. This fermentation is often indicated by a change in pH or the production of gas in a fermentation tube. Therefore, glucose is commonly used as a substrate to assess the fermentation capabilities of various microorganisms.
Why does Bacillus cereus ferment Glucose and not Lactose or Sucrose?
Because bacillus cereus is a Gram-positive, spore-forming, and rod-shaped, it\'s only able to ferment glucose.
What is a VP test for bacillus?
A VP (Voges-Proskauer) test for Bacillus is used to determine the ability of the bacteria to produce acetoin from glucose fermentation. A positive VP test result is indicated by the development of a red color after the addition of Barritt's reagents A and B, showing the presence of acetoin.

What is the glucose test result of streptococcus faecalis?
It is positive for the metabolizing of glucose.
What is a cellular respiration and not a fermentation?
Cellular respiration produces water but fermentation does not.Respiration: glucose + oxygen --> carbon dioxide + water Fermentation: glucose --> alcohol + carbon dioxide
