What is Oxidase test results for bacillus subtilis?
Bacillus subtilis is positive for the oxidase test. This means that it has the enzyme cytochrome c oxidase, which is needed for the bacterium to produce energy through aerobic respiration. The positive result is indicated by the appearance of a color change (usually dark purple) on the test strip after adding the reagent.
Is bacillus subtilis catalase positive or negative?
Bacillus subtilis is catalase positive, meaning it produces the enzyme catalase which can break down hydrogen peroxide into water and oxygen.
Does bacillus subtilis perform starch hydrolysis?
yupp
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.
Which bacteria is amylase positive catalase positive cysteine desulhydrase negative nitrate reduction negative glucose positive lactose positive sucrose positive citrate positive?
bacillus subtilis
Does the bacillus cereus growth on Phenylethyl Alcohol agar?
Yes, Bacillus cereus can grow on Phenylethyl Alcohol agar as it is a selective medium used for isolating Gram-positive organisms including Bacillus species. The agar contains phenylethyl alcohol which inhibits the growth of Gram-negative bacteria, allowing for the selective growth of Gram-positive bacteria like Bacillus cereus.
Is bacillus subtilis positive for glucose fermentation?
Yes, Bacillus subtilis is capable of fermenting glucose. It produces acid from glucose fermentation, which is usually detected on differential media containing indicators such as phenol red.
What is the result of citrate test for bacillus subtilis?
blue/positive
Is Bacillus subtilis a photoautroph?
No, Bacillus subtilis is not a photoautotroph. It is a heterotrophic bacterium, meaning it obtains its energy and carbon from organic compounds in its environment rather than from photosynthesis.
What is the morphology and arrangemen of bacillus subtilis under microscope?
Bacillus subtilis is a rod-shaped bacterium that forms chains or pairs under the microscope. It has a uniform width and can be motile due to flagella. The cells are typically Gram-positive and may produce endospores under unfavorable conditions.
What species does bacillus subtilis belong to?
It's part of the Bacillus species, which also includes B. cereus (a common bacteria in food poisoning known for being present in poorly reheated rice). These two bacteria are spore forming gram positive bacilli (rods).
Does bacillus subtilis have a positive reaction for ONPG Test?
No, Bacillus subtilis does not have a positive reaction for the ONPG test. This test is used to detect the presence of β-galactosidase enzyme, which is not produced by Bacillus subtilis.
