The oxidative-fermentative test is used to determine if gram-negative bacteria metabolize carbohydrates oxidatively, by fermentation, or are nonsacchrolytic and therefore have no ability to use the carbohydrate in the media.
below 6.8
triple sugar iron agar is called the multi test because in this test we differentiate the enteric pathogen on the basis of different carbohydrate fermentation i.e glucose,sucrose and lactose.as well as we differentiate on the basis of gas and h2S production....
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.
Biochemical test give to genus level for the bacterial identification ( imvis,hydrolysis,sugarfermentation, carbohydrate fermentation and decarboxylase).

the most commonly used biochemical test to identify lactobacillus is carbohydrate fermentation, this is the preliminary screening test and an essential test for the identification of lactobacilli
Phenol Red is used in this testing because it offers a mid-range pH balance. The color changes from red to yellow when the test is complete.

nobody knows
media used for oxidase test is non selective media
No, it is negative.B. subtilis on EMB agar:http://www.microbelibrary.org/microbelibrary/files/ccImages/Articleimages/Atlas_EMB/Bacillus-subtilis_EMB_fig11.jpg
