The range of G + C base content in bacterial DNA ranges between 25% to 75%. The reason for using this method to identify related bacterial strains is that different strains accumulate different mutations over time.
No, Streptococci are bacteria that form chains.
It is positive for the metabolizing of glucose.
Pathogenic streptococci will typically exhibit virulence factors like toxins or adhesins that contribute to their ability to cause infection, while strains within the normal microbiota lack these factors. Pathogenic strains may also show antibiotic resistance or heightened ability to invade host tissues, compared to commensal streptococci. Furthermore, the host immune response to pathogenic streptococci may differ significantly from those elicited by commensal strains.
Streptococci grow best in a warm and moist environment with a slightly acidic pH. They require a source of nutrients such as sugars or proteins for growth. Oxygen availability can vary depending on the species of streptococci, with some requiring oxygen (aerobic) and others not (anaerobic).
a bacitracin susceptibility test and a SXT sensitivity test can be done. if the organism is bacitracin resistant and susceptible to SXT it is termed a Non-group A or B beta-hemolytic streptococcus. thus it is probably in group C
The Snyder Test is an oral test that evaluates the lactobacilli and oral streptococci in a person mouth. There is no specific time of day that is best but people prefer the morning time.
The Snyder test for tooth decay it can be done at any time of the day. The test is meant to evaluate levels of lactobacilli and oral streptococci if the results come after 72 hours.

Thermophilic, lactobacilli or streptococci are the 3 most common bacterial cultures used that I know of. There might be more. Thermophilic is usually used when the cheese will be heated to a high tempature. This culture survives this step, where the other 2 don't.

Streptococci are bacteria that belong to the genus Streptococcus. There are 27 species of Streptococcus bacteria. The most well known bacteria in the group is Streptococcus pyogenes which is the bacteria that causes Strep throat.
The plural of streptococcus is streptococci.
