Vinasse

From Wikipedia, the free encyclopedia

Vinasseis abyproductof thesugarorethanolindustry.[1]Sugarcaneorsugar beetis processed to producecrystallinesugar,pulp andmolasses.The latter are further processed byfermentationtoethanol,ascorbic acidor other products. Juice sugarcane can also be processed directly by ethanol fermentation. After the removal of the desiredproduct(alcohol,ascorbic acid,etc.) the remaining material is called vinasse. Vinasse is sold after a partialdehydrationand usually has aviscositycomparable tomolasses.Commercially offered vinasse comes either fromsugar caneand is called cane-vinasse or fromsugar beetand is called beet-vinasse. Vinasse produced from sugar cane is also calleddunder.[2]

In the process ofdistillationof the alcohol and as a result of the heating in the distillation process, in the pulp of the beet reactions ofcondensationand predominantly molecular ruptures take place. This causes a highfulvic acidconcentration in this byproduct. One use of vinasse is inthermophilic digesters.InBrazil,thermophilic digestionis a source ofbiogasusing pure and hot vinasse as the source of production of methane. In the past, vinasse was a problem in production ofethanol,but vinasse is also a goodfertilizer(at least for some time) and a source ofmethanethat can be used to generate heat or electricity. Moreover, other uses of vinasse involving also the formulation of nutritive solutions for hydroponics,[3]formulation of culture media for plant tissue culture[4]and culture media for algal growth.[5][6]

(KCV1 and KCV5) Vinasse used to formulate culture media for thein vitroelongation and rooting ofOncidium leucochilum(orchid), (KC) medium Knudson C used as control. In order to formulate the vinasse media was used a dilution of 2.5% vinasse. These culture media are free of plant growth regulators (Silva et al., 2014).
