You push the bacterial sample into the media because it acts as the anaerobic environment so by using the side of the tube and the agar within it gives you both anaerobic environment and aerobic environment.
After 48 hours incubation with e coli, the TSI media will be in black in color.
The TSI media will be black in color after 48 hours incubation of proteus vulgaris gram.
The color that would TSI media be after 48 hours icubation with enterobacter aerogenes is black.
There is no definitive answer to this question since meningitis can be caused by a variety of things, including bacteria, viruses, and other types of microorganisms, each of which would have a different incubation time.
To cultivate bacteria, you would typically streak a sample onto a nutrient agar plate in a sterile environment. The plate is then incubated at the optimal temperature for the specific bacteria species to grow. After incubation, colonies of bacteria will form, which can be studied and analyzed.

Anaerobic bacteria would not grow in an oxygen-rich environment due to their sensitivity to oxygen. These bacteria require low oxygen levels or no oxygen at all to thrive and reproduce.
The color of TSI media after 48 hours incubation with Pseudomonas aeruginosa would typically be yellow. Pseudomonas aeruginosa is a non-lactose fermenting bacterium, so it does not produce acid in the medium. This results in the production of a yellow color due to the pH indicator in the TSI media.

The conclusion drawn if no growth appeared on MacConkey agar and EMB agar after inoculation of the media and an incubation period could be the bacteria used was possibly a Gram positive non-enteric sample.
If incubation surpasses 5 days, the bacteria may degrade indole to the point that a FALSE negative would result.
