i have an assignment that i need to find all the papers that talks about this topic the biodegradation of chlorpyrifos by co culture of serratia sp and trichosporon sp

Hi there, I have a bibliography assignment for a course called (intro DNA molecular methods). I basically need help to search for any existing papers that talks about this topic (the biodegradation of chlorpyrifos by co-culture of Serratia sp. and Trichosporon sp) and I’ve spend a couple days now searching the literature and I can’t find another paper than the one I found (attached) that talks about the same topic … If I am right I’ll get 100% on the assignment …. but if I am wrong they deduct marks for every paper they find related to the topic …. it’s always possible to find papers talks about this topic … I suppose if we think of different search terms or something …. so we would be looking for another paper that talks about removing chlorpyrifos using co-cultures of the sp I mentioned above??

I attached the only paper I found about this topic hopefully you will be able to help me to find more papers

this is the link for the paper as well https://www.researchgate.net/publication/6227632_M…
