Title
Identification of regional products microbiota and its growth dynamics determination using the conventional culture-dependent methods
Disponível na Biblioteca da ESACB na cota C30-27420TFCEBA. In this study samples of regional fermented polish foods like milk, Pumpernickel bread
and fried cheese from the Wielkopolska region of Poznan were tested to find which type of
microorganisms we can find in these types of fermented foods and their differences.
The samples were collected in specialized factories and each was collected several times
but these correspond to different stages of production. The objective is to verify how the
evolution and presence of microorganisms takes place and in which stages of production its
needed to have more attention for health security and which type of organisms we can find in
the different production stages.
Also the purification, isolation and storaging of strains of the different microorganisms
found were performed in order to proceed to further studies of these products and organisms.
In order to perform this study several media were tested to decide and obtain the best
results in the growth of the different organisms.
Once the strain is isolated in the proper media it was tested by biochemical analysis and
computer program confirmation to find the microorganism discovered in the different foods.
