Influence of inoculation with Lactobacillus on fermentation, production of 1,2-propanediol and 1-propanol as well as Maize silage aerobic stability

Abstract

<jats:title>Abstract</jats:title><jats:p>The aim of this study is to determine the influence of a commercial bacterial inoculant (L1) and a preparation (L2) containing three <jats:italic>Lactobacillus</jats:italic> strains capable of producing 1,2-propanediol and short-chain fatty acids on maize silage aerobic stability improvement. The research showed that during 90-day ensilage, the applied preparations significantly reduced the content of DM, water-soluble carbohydrates (WSCs), pH and DM recovery (<jats:italic>P</jats:italic> &lt; 0.05). The concentration of lactic acid (LA), acetic acid (AA) and propionic acid (PA) in the inoculated samples increased significantly (<jats:italic>P</jats:italic> &lt; 0.05). 1,2-Propandiol and 1-propanol were not found in control silages (without additives). The addition of L1 and L2 significantly (<jats:italic>P</jats:italic> &lt; 0.05) increased the concentration of these substances. The L1 and L2 mixtures significantly extended (<jats:italic>P</jats:italic> &lt; 0.05) the silage aerobic stability.</jats:p>

Increasing Biogas Yield from Fodder by Microbial Stimulation of Propionic Acid Synthesis in Grass Silages

“…Silages inoculated with starter culture consisted of L. buchneri ATCC 4005, L. diolivorans LGM 19667 and L. reuteri ATCC 23272 contained 1.4 g/100 g dm. No1,2-propanediol and 1-propanol were found in the control samples [29]. The same observations were made in our research.…”

A Preliminary Study on Effects of Fermented Feed Supplementation on Growth Performance, Carcass Characteristics, and Meat Quality of Hanwoo Steers during the Early and Late Fattening Period

“…On the other hand, water-soluble carbohydrates are fermented by homofermentative bacterial inoculants into organic acids, especially lactic acid, which can quickly acidify silage and inhibit the growth of undesirable bacteria. To regulate the growth of yeast, homolactic inoculants, such as lactobacilli, known to produce acids, such as acetic and propionic acids, that inhibit the growth of microorganisms that trigger spoilage [30] were added. Inoculants include one or two groups of acidophilic bacteria.…”
