These are old non valid names for a couple of lactic bacteria
B gracile is Lactobacillus gracilis and S muc.is either
Leuconostoc messentoides or Pediococcus.
Both can ferment residual sugars to lactic acid
and also some varieties can ferment malic acid to
lactic acid reducing wine acidity.
In the presence of cane sugar Leuc. and Ped. are
both able to break down sucrose producing a dextran or
fructan slime in the product.
