What else can I help you with?
Does C glutamicum ferment lactose?
No, C. glutamicum is not able to ferment lactose as it lacks the necessary enzymes to metabolize this sugar. Instead, C. glutamicum is known for its ability to ferment glucose, sucrose, and other sugars to produce amino acids.
What carbohydrates can Enterobacter aerogenes ferment?
Enterobacter aerogenes can ferment a wide range of carbohydrates, including glucose, lactose, sucrose, and maltose. It possesses various enzymes to break down and metabolize these sugars for energy and growth.
Does sporosarcina urea ferment glucose?
Sporosarcina ureae is able to ferment glucose through the Embden-Meyerhof-Parnas pathway, producing energy and various byproducts such as organic acids and gases. This fermentation process helps the organism generate ATP for its metabolic activities.
Why salmonella typhimurium does not ferment lactose?
Salmonella typhimurium does not ferment lactose due to the absence of the necessary enzymes, specifically β-galactosidase, which is required to break down lactose into glucose and galactose. Instead, it primarily relies on other carbohydrates and proteins for energy. The inability to ferment lactose is a distinguishing feature used in laboratory identification and differentiation from other enteric bacteria, such as E. coli, which can ferment lactose.
Is Staphylococcus aureus lactose frementing bacteria?
Yes, it can ferment lactose. Mannitol Salt Agar is used to identify S.aureus. When it ferments D-mannitol, it produces an acid which turns the agar yellow from red. S.epidermidis will grow, but the agar remains red.
Is P vulgaris a lactose fermenter?
Yes, P. vulgaris is a lactose non-fermenter. It does not possess the enzyme beta-galactosidase needed to ferment lactose into glucose and galactose. Instead, it typically ferments sugars like glucose and sucrose.
Does C glutamicum ferment lactose?
No, C. glutamicum is not able to ferment lactose as it lacks the necessary enzymes to metabolize this sugar. Instead, C. glutamicum is known for its ability to ferment glucose, sucrose, and other sugars to produce amino acids.

Does sporosarcina urea ferment glucose?
Sporosarcina ureae is able to ferment glucose through the Embden-Meyerhof-Parnas pathway, producing energy and various byproducts such as organic acids and gases. This fermentation process helps the organism generate ATP for its metabolic activities.
Does Morganella Morganii ferment lactose?
no, it shows negative for lactose fermentation on MacConkey's agar
What type of bacteria is typhoid causing bacteria?
The are gram negative bacillus shaped bacteria. They are facultative anaerobic bacteria. They ferment the glucose to produce acid and gas. They ferment the sulfur containing amino acids to produce H2S gas. They do not ferment the lactose.
Is bacillus subtilis positive for glucose fermentation?
Yes it is. Bacillus subtilis produces endospores?
Does E. coli ferment sucrose?
Yes, E. coli can ferment sucrose. It produces the enzyme invertase to break down sucrose into glucose and fructose, which are then utilized through glycolysis for energy production. This fermentation process produces acids and gases as byproducts.
Does citrobacteria ferment lactose?
Yes, Citrobacter species are capable of fermenting lactose. They possess the necessary enzymes to break down lactose into glucose and galactose, allowing them to use lactose as a source of energy.
Is Staphylococcus aureus lactose frementing bacteria?
Yes, it can ferment lactose. Mannitol Salt Agar is used to identify S.aureus. When it ferments D-mannitol, it produces an acid which turns the agar yellow from red. S.epidermidis will grow, but the agar remains red.
Explain why the TSI medium contains a lower concentration of glucose than of lactose and sucrose?
When any sugar is metabolized under anaerobic conditions (fermentation), there is increased acid production; thus the butt of the tube remains acid for a longer period of time. When glucose only is fermented, acid is produced throughout the medium but due to the relatively low concentration of glucose in the medium and the aerobic metabolism that is present on the slant, nitrogenous metabolic end products soon change the reaction of the slant to alkaline. These alkaline products neutralize the small amounts of acids present in the slant but are unable to neutralize the large amounts acid present in the butt. Thus, the appearance of an alkaline (red) slant and an acid (yellow) butt after 24 hours incubation indicates that the organism is a glucose fermenter but is unable to ferment lactose and sucrose. Bacteria that ferment lactose or sucrose (or both), in addition to glucose, produce such large amounts of acid that the oxidative deamination of protein that may occur in the slant does not yield enough alkaline products to cause a reversion of pH in that region. Thus, these bacteria produce an acid slant and acid butt. The inclusion of sucrose permits separation of certain Proteus organisms which ferment sucrose from the salmonellae since both of these groups of organisms are lactose-negative and both may produce hydrogen sulfide.AC
Does bacillus megaterium ferment glucose?
Yes, Bacillus megaterium is capable of fermenting glucose through the process of glycolysis to produce ATP and other metabolic byproducts like organic acids, alcohol, and gases.
