Twenty‐one strains of lactic acid bacteria were subjected to a range of tests based on established criteria to ascertain their suitability for use as inoculants for silage. The tests included a monitor of their growth in the presence of representatives of the microflora of forage crops with which they might have to compete for substrate, and their ability to effect rapid acidification and achieve a low pH in conditions which simulate low and high ensiling potential. In addition, their ability to produce acid from sugars and their action against organic acids found in forage crops, together with their tolerance of acid, elevated temperatures and conditions of low moisture availability (e.g. in wilted material) and possible proteolytic and amylolytic activities were examined. None or these cultures satisfied all of these criteria. However, three strains ( Streptococcus durans str. 1024, Lactobacillus acidophilus , str. 2356 and Lactobacillus plantarum str. 6) had a greater potential than the others.
