In this thesis peptides with biological activity have been separated and identified, mainly peptides with antihypertensive activity in commercial fermented milk with Streptococcus thermophilus and Lactobacillus acidophilus, during refrigerated storage. This thesis is structured in three parts. In the first part analysis of soluble peptides determination by Lowry technique was...
Recently, the solid state fermentation (SSF) has been regarded as a big potential process for the development of bioprocesses and products. Among their applications one can find enzyme production that is mainly extracellular. The oxygenases are intracellular enzymes that catalyze reactions in which oxygen atoms from molecular oxygen are directly...
