Abstract
P.S. COCCONCELLI, E. TRIBAN, M. BASSO AND V. BOTTAZZI. 1991. A technique to monitor lactic acid bacteria inoculants in silage, based on specific DNA probes, was developed and used to evaluate the colonization properties of two strains of Lactobacillus plantarum and one strain of Pediococcus pentosaceus which were used as maize silage inoculants in farm conditions. The results indicated that these three strains were able to dominate the natural microflora of the silage, representing more than the 95% of the bacterial biomass of the maize silage. These studies indicate that the colony hybridization with specific DNA probes may be an effective method for monitoring bacteria and evaluating the colonization properties of inoculants in maize silage.
