Streptococcus agalactiae (also known as Group B Streptococcus, or GBS) from other streptococci, biochemical testing is essential. The most prevalent streptococci pathogen in humans, S. agalactiae, is categorized as belonging to group B in Rebecca Lancefield’s streptococci taxonomy. A bacterial capsule made of polysaccharides (exopolysaccharide) envelops GBS. The species’ immunologic reactivity of its polysaccharide capsule […]
Mycobacterium tuberculosis is pathogenic bacterium causes human tuberculosis (TB) .It is a distinct biochemical bacillus that reacts quickly to acid. A battery of tests is used to distinguish Mycobacterium tuberculosis from other mycobacteria and germs in order to identify it. The following is a summary of the essential biochemical tests and traits used to diagnose
Haemophilus influenzae is a facultatively anaerobic Gram-negative bacterium that can cause a wide range of illnesses, especially in young infants. In addition to respiratory tract infections, it has been linked to more serious illnesses such meningitis and septicemia. Biochemical tests are used to detect and distinguish Haemophilus influenzae from other germs. The following are some
Edwardsiella tarda is a frequent Gram-negative, facultatively anaerobic bacterium in freshwater and marine environments. It has been reported to infect people and fish on occasion. Biochemical tests are used to identify and distinguish Edwardsiella tarda from other bacteria. The following are some essential biochemical traits and assays for Edwardsiella tarda Edwardsiella tarda Gram Stain Oxidase
Burkholderia pseudomallei is the bacterium rod-shaped, Gram-negative bacterium that causes melioidosis, a serious infectious disease. Numerous biochemical assays are used to identify this organism and help set it apart from other bacteria that are identical to it. These are the main Burkholderia pseudomallei biochemical assays. Burkholderia pseudomallei Biochemical Test of Burkholderia pseudomallei Gram Staining Oxidase
Aeromonas hydrophila is the rod-shaped, facultatively anaerobic, gram-negative bacterium frequently found in aquatic settings. It is well recognized to infect both people and animals with a wide range of illnesses. The identification and characterization of this bacteria depend on biochemical assays. The main biochemical assays that are used to identify Aeromonas hydrophila are summarized below.
Bial’s Test is a biochemical test used to determine whether pentoses, or sugars with five carbons, are present in a sample. When separating pentoses from hexoses (six-carbon sugars) and other carbohydrates, this test is especially helpful. A chemical test called Bial’s Test is used to identify pentose carbohydrates. The test is based on the production

Batch ,Fed Batch , Continuous Culture belongs to microbial culture method. Batch Culture Definition One kind of microbial culture technique in which microorganisms are cultivated in a closed system with a set volume of nutrient solution. With this approach, all nutrients are provided at the start of the cultivation process, and no more are added while

Bacterial Growth refers to the increase in the number of bacterial cells in a population. This process occurs through binary fission, where a single bacterial cell divides into two genetically identical daughter cells. Bacterial Growth is not about the enlargement of individual cells but rather about the reproduction and increase in the cell population. Rather

Bacillus cereus the rod-shaped, gram-positive bacterium is present in soil, plants, and food, among other environmental sources. It is well recognized to cause foodborne diseases, especially when toxins are produced. Based on the toxins generated and the ensuing symptoms, Bacillus cereus food poisoning is commonly divided into two categories: emetic (vomiting) and diarrheal .Spore-forming bacteria
