Soon later, Vulevic and co-workers [2004] meliorate the PI by including more bacterial groups (positive bacteria eubacteria and negative bacteria Escherichia coli, and sulphate-reducing bacteria) fermentation end products, such as short chain fatty acids (SCFA) and substrate assimilation aiming to compare their fermentation profiles on a quantifiable basis.
