Abstract
It was found that lipase production during the growth of Pseudomonas fluorescens was not a function of the total number of bacteria. The optimal temperatures for bacterial growth and lipase production were determined as 20 and 8 degrees C, respectively. The lipolytic activity was studied in emulsions of olive oil at temperatures ranging from +8 to -30 degrees C. After an initially rapid lipolysis, the reactions retarded at different levels depending on storage temperature. Transference to a higher temperature resulted in a resumed lipolysis. Also, at low temperatures, lipolysis was studied as a function of water activity and was found to occur in dehydrated substrates.
