I consulted all of these resources before making this post. I also searched
databases such as PubMed. Obtaining information on food spoilage organisms
is not simple. I am familiar, for instances with the changes in the taxonomy
of the genus Bacillus- the creation of genera such as Alicylcobacillus,
Aneurinibacillus, Paenibacillus. I also know that no food microbiology
textbook I have read explains the role of proteases, lipases or amylases in
the spoilage caused by Bacillus species. I have worked with rope formation
caused by Bacillus subtilis and know the pitfalls of the rope spore test and
the lack of predictive ability. I have publications on bakers yeast, food
poisoning due to B. cereus and the detection of bacillus sp. in foods. I
think, therefore, I have done my homework.

I was hoping that someone in this newsgroup might have some specialist
knowledge, opinions or could give some leads to investigatebthese areas
further
