Science Database about Bacteria?

Hi. I’ll try and make this as concise as possible.

I am doing a lab report for my biology class regarding a specific type of bacteria called S. marcescens.

One of the easiest parts of this lab report I can not seem to get past.

I need to find a reliable source that states the optimal growth conditions (specifically temperature and PH for now) for this bacteria. We performed our own test in lab and observed what we saw as the optimal conditions but I need to find someplace else that either states the “generally known” optimal condition or another paper describing someone else that performed a similar study and state whatever they observed.

The only place I can find info on this is MicrobeWiki which states its source as Wikipedia, which is not considered a reliable source.

I found other papers out there testing for other things related to S. marcescens and they state the known optimal growth temp as 30°C but cite no source.

Is there some kind of bacteria science database out there that records this information and excepts it as standard that I can cite? I just need to move on from this.
