In wheat, for example, Li, Wang, Cai, and Pang (2015) detected a high number of heterofermentative microorganisms, contributing with 66.7% of the total lactic acid bacteria; these microorganisms have a distinct fermentation pattern, leading to the formation of different compounds, such as acetic acid and 1,2-propanediol, which result in higher losses of DM compared to the homolactic pathway, which could justify the greatest losses found (Muck, 2010).
