the answer i would like to give. there are many biochemical tests for detection of various types of bacteria. 1. carbohydrate utilization tests (sugar test). - lactose , sucrose , mannitol , maltose , xylose and dextrose. 2. imvic test. it includes indole test , methyl red test , voges proskuer test , citrate utilization test. 3. nitrate reduction test. 4. urease test 5. triple sugar iron test. 6. lead acetate test. 7. mannitol motility test 8. O-F (oxidation - fermentation) test 9. aminoacid degradation test we can detect enterobacteriaecae group & other group of bacilli according to their charactristics by comparing with standard table.

What kingdom is gram positive bacteria?
Kingdom Gram-Positive Bacteria is a kingdom within the domain Bacteria.
Is azospirillum a gram positive bacteria?
Gram positive
What are key markers for the identification of Bacteria?
Key markers for the identification of bacteria include morphological characteristics such as shape (cocci, bacilli, spirilla), staining properties (Gram-positive or Gram-negative), and growth conditions (aerobic or anaerobic). Biochemical tests, such as fermentation profiles and enzyme activity (e.g., catalase or oxidase tests), also play a crucial role. Additionally, molecular techniques like PCR and sequencing of specific genes (e.g., 16S rRNA) can provide accurate identification at the species level.
How do you isolate and identify gram positive cocci?
Gram positive cocci can be isolated and identified through Gram staining, which involves using a series of dyes to distinguish between different types of bacteria based on their cell wall composition. Once isolated, additional tests such as catalase test, coagulase test, and biochemical tests can help further identify specific species of gram positive cocci such as Staphylococcus and Streptococcus. Additionally, molecular techniques like PCR and sequencing can be used for precise identification.
Which type of bacteria are present in curd either gram plus ve or gram -ve bacteria?
The bacteria present in curd are primarily Gram-positive bacteria. These include species like Lactobacillus acidophilus and Streptococcus thermophilus. Gram-negative bacteria are not typically found in curd as the fermentation process favors the growth of Gram-positive bacteria.
What kingdom is gram positive bacteria?
Kingdom Gram-Positive Bacteria is a kingdom within the domain Bacteria.
Is azospirillum a gram positive bacteria?
Gram positive
Does Gram-positive bacteria have lipopolysaccharides?
No, Gram-positive bacteria do not have lipopolysaccharides.
Why to gram stain bacteria?
gram staining is a biochemical method of identifying bacteria in a more specific way.Thus it is important to differentiate gram positive and gram negative bacteria.
Is lactobacillus bacteria gram positive bactaria?
Lactobacillus is gram positive bacteria
Do gram positive bacteria have an outer membrane?
No, gram positive bacteria do not have an outer membrane.
Do gram positive bacteria have lipopolysaccharides (LPS)?
No, gram positive bacteria do not have lipopolysaccharides (LPS).
Does Gram-positive bacteria have an outer membrane?
No, Gram-positive bacteria do not have an outer membrane.
What is the structural difference in the cell walls of gram-negative bacteria that distinguishes them from gram-positive bacteria?
Gram-negative bacteria have a thinner peptidoglycan layer in their cell walls compared to gram-positive bacteria. Additionally, gram-negative bacteria have an outer membrane that contains lipopolysaccharides, which is absent in gram-positive bacteria.
Is Staphylococcus saprophyticus gram positive or negative?
Yes. Staphylococci are classified as gram positive bacteria and appear as purple spheres when Gram stained.
Is acid fast bacteria gram positive or negative?
Acid-fast bacteria are gram-positive.
Is lactobacillus casei is a gram negative bacteria or gram positive?
The Bacteria Sarcina lutea is Gram Positive Because If You Perform the Gram Test It Will Turn The Violet Color Which indicates It's Positiveness. What Makes It Positive Is the Peptidoglycan Located Within The The Bacterium
