AIMS The objective of this work was to evaluate the fermentation pattern of and the exopolysaccharide (EPS) production by Lactobacillus helveticus ATCC 15807 in milk batch cultures under controlled pH (4.5, 5.0 and 6.2). METHODS AND RESULTS EPS concentration was estimated by the phenol/sulphuric acid method and the chemical composition of purified EPS by HPLC. Fermentation products and residual sugars were determined by HPLC and enzymatic methods. The micro-organism shifted from a… CONTINUE READING
