Is bacillus subtilis positive for glucose fermentation?
B. subtilis does not ferment glucose nor lactose
Why are some organisms positive in the ONPG Test but negative when tested for the ability to metabolize lactose?
ONPG is for the detection of delayed lactose fermentation.
Is Pseudomonas luteola oxidase positive?
in the absence of glucose or lactose , some bacteria are able to use citrate as only source of carcon. alkaline pH change the bromothymol blue indicator from green to blue. pseudomonas can not ferment the glucose and the lactose so it use the citrate as carbon source.
Does Morganella Morganii ferment lactose?
no, it shows negative for lactose fermentation on MacConkey's agar
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.
Is bacillus subtilis positive for glucose fermentation?
B. subtilis does not ferment glucose nor lactose
Which bacteria is amylase positive catalase positive cysteine desulhydrase negative nitrate reduction negative glucose positive lactose positive sucrose positive citrate positive?
bacillus subtilis
Is bacillus cereus lactose positive?
No
Why are some organisms positive in the ONPG Test but negative when tested for the ability to metabolize lactose?
ONPG is for the detection of delayed lactose fermentation.
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.
Lactose fermentation mac conkey test which color indicate a positive test?
MacConkey agar is yellow (due to the lactose in the agar). When an organism consumes the lactose, the agar turns purple. Purple indicates a positive test. If the organism doesn't use the agar, the agar stays yellow.
Is Pseudomonas luteola oxidase positive?
in the absence of glucose or lactose , some bacteria are able to use citrate as only source of carcon. alkaline pH change the bromothymol blue indicator from green to blue. pseudomonas can not ferment the glucose and the lactose so it use the citrate as carbon source.
Does Morganella Morganii ferment lactose?
no, it shows negative for lactose fermentation on MacConkey's agar
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 micrococcus roseus test positive for mixed acid fermentation?
Micrococcus roseus ferments sucrose, but no gas. Does not ferment lactose, glucose, or mannitol. Beta hemolitic. Catalase positive. Pink colonies of groth

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.
