[Microbiology] any suggestion for a set of biochemical tests

[ALIREZA BEDELTAVANA]

Dear Sir
I am working on  the contamination of Milk with Gram-negative psychrotrophic spoilage bacteria during pasteurization process and  I need   a set of biochemical tests  to diagnose and differentiate different species of this bacteria ,specially pseudomonas florescence. I prefer the set be small and more convenient.
 
Do you have any suggestion to help me?
