Influence of Lactobacillus spp. from an inoculant and of Weissella and Leuconostoc spp. from forage crops on silage fermentation
Article Abstract:
Research was conducted to examine the characterization of Leuconostoc and Weissella species isolated from forage crops as well as their influence on silage fermentation. Results confirmed that the inoculation with L-lactic acid-producing lactobacilli had beneficial effects on decreasing the proportion of D-isomer to total lactic acid and improving silage quality. Findings also showed that the heterofermentative lactic acid bacteria strains Weissella paramensenteroides FG5 and Leuconostoc pseudomesenteroides FG 13 did not improve silage quality and may cause some fermentation loss.

Assessment of Pediococcus acidilactici as a potential silage inoculant
Article Abstract:
Eighteen Pediococcus acidilactici strains were evaluated for their potential as silage inoculants. Among the strains tested, P. acidilacti G24 was the most suitable for silage inoculation. In vitro experiments showed that strain G24 could also encourage the growth of natural Lactobacillus plantarum populations. One strain, PLL07, did not aid in the preservation of laboratory silos. These results suggest that strain G24 is a useful silage inoculant. Other Pediococcus strains may also have potential, however, care must be taken in selecting specific strains for silage inoculation.

Growth and survival of genetically manipulated Lactobacillus plantarum in silage
Article Abstract:
Two genetically manipulated forms of Lactobacillus plantarum were studied for their growth and persistence in grass silage. Both recombinants contained a gene for erythromycin resistance called pSA3. One had pSA3 incorporated in its chromosome and the other had a pSA3 derivative maintained in a plasmid. Both strains proliferated in silos to a similar extent as the parent strain, which was used as a control. All of the L. plantarum strains eventually dominated the silage microflora. The presence of this extra genetic material therefore did not affect growth and survival.
