TIP: Glycolysis is metabolic pathwya
fermentation when anaerobic
If facultative anaerobe , will go krebs as can utilise more energy
Krebs if aerobe
OF test, oxidative result
pseudomonas aeruginosa
oil keeps anaerobic
Fermentation; yellow/yellow a
A facaelis green green with blue as hydrolysing peptones but negative result
