Williams (2008) reported enhanced growth of Selenomonas ruminantium
and Streptococcus bovis in response to high SS levels, which is in accordance with the high level of SS, which were identified as Selenomonas sp.
Consequentemente, ocorre estímulo no crescimento de Selenomonas ruminantium
, que utiliza ácido lático como substrato contribuindo para o equilíbrio da flora ruminal (García et al.
Moreover, this was probably due to some effects of the yeast contained in YEFECAP that stimulated the growth and metabolism of rumen microorganisms especially lactate-utilizing bacteria, such as Megasphaera elsdenii or Selenomonas ruminantium
(Lynch and Martin, 2002).
Fibrobacter succinogenes S85 and Selenomonas ruminantium
(Heinrichova et al.
The influence of mercury on the antioxidant enzyme activity of rumen bacteria Streptococcus bovis and Selenomonas ruminantium
PCR primers for the following taxa have been described previously (Stevenson and Weimer, 2007): Butyrivibrio fibrisolven, Prevotella ruminicola, Megasphaera elsdenii, Selenomonas ruminantium
, and Streptococcus bovis.
Lactic acid-utilizing bacteria such as Megasphaera elsdenii, and Selenomonas ruminantium
play a central role in preventing the accumulation of ruminal lactic acid in grain-adapted cattle (Counotte et al.
, Veillonella parvula and Wollinella succinogenes reduce nitrate and nitrite (Stewart and Bryant, 1988).
Propionate and succinate producers such as Selenomonas ruminantium
, Megasphaera elsedenii, and Succinivibrio dextrinosolvens were tolerant to these two materials, while hydrogen and formate producers such as Ruminococcus flavefaciens, Ruminococcus albus, Butyrivibrio fibrisolvens, and Eubacterium ruminantium were sensitive.
10% increased the growth rates of ruminal noncellulolytic bacteria including Bacteroides amylophilus, Megasphaera elsdenii, Prevotella ruminicola and Selenomonas ruminantium
and ruminal cellulolytic bacterium, Fibrobacter succinogenes which is considered to be the most effective in utilizing cellulose from plant tissues (Miller, 1959).
Effect of dicarboxylic acids and Aspergillus oryzae fermentation extract on lactate uptake by the ruminal bacterium Selenomonas ruminantium
For example, fermentation of malate does not yield energy; however, malate can stimulate a ten-fold increase in the ability of Selenomonas ruminantium
to use lactate (Callaway and Martin, 1997).
