Definitions

  • the present invention relates to a process for edible fungal cultivation by employing vinasse or spent wash of first generation ethanol production as a substrate. More particularly, the present invention relates to a process for edible fungal cultivation in the form of pellets. Further, the present invention relates to the integration of fungal cultivation into the first generation sugar to ethanol production.
  • Sugarcane or sugar beet is one of the most abundantly used feedstocks for bioethanol production worldwide.
  • Ethanol is produced by fermentation of plant crops containing starch and sugar such as wheat, sugarcane, sugar beet and corn.
  • Ethanol production from sugar is either directly obtained from sugarcane juice which is extracted from sugarcane or from beet sugar leaving behind bagasse that is generally used for electricity or energy generation or from molasses, a low value co-product of raw sugar production.
  • cane juice is the dominant feedstock for ethanol production in most Brazilian factories, a large number of producers in Indonesia, India, the Caribbean, and a significant number in Brazil, mostly manufacture ethanol from molasses.
  • Molasses is used either as a cattle feed supplement in specialized yeast propagation, as a fertilizer, or as a flavoring agent in some foods.
  • fermentable sugars in molasses cannot be further upgraded to raw sugar, they can be converted to ethanol in a distillery using conventional ethanol fermenting microorganisms such as yeast.
  • integrated sugarcane factories having a sugar manufacturing industry co-located with an ethanol distillery can use molasses as a feedstock for ethanol production in addition to raw cane juice directly from the mill.
  • a significant number of sugarcane factories in Brazil and India and several other such factories employ this strategy of integrating sugar industries with ethanol distilleries.
  • V inasse is the final by-product of biomass distillation, mainly for production of ethanol, from sugar crops (beet and sugarcane), starch crops (corn, wheat, rice, and cassava), or cellulosic material (harvesting crop residues, sugarcane bagasse, and wood).
  • V inasse is usually produced as an acidic compost having pH varying from about 3.5 to about 5, a dark brown slurry, with high organic content (chemical oxygen demand 50 " 150 g L B1 ), and characterized by an unpleasant odor, with high contents of potential hazardous substances (Christofoletti et al., 2013). It has been estimated that for every liter of ethanol, around 12 " 15 L of residue is produced.
  • vinasse applied to farming lands as fertilizer can cause serious water and soil pollution, such as leaching of metals to groundwater, changes in soil quality, increase of phototoxicity, unpleasant odor, as well as leading to considerable methane emissions during temporary storage or transportation and also nitrous oxide emissions (Carmo et al., 2013; Christofoletti et al., 2013; De Oliveira et al., 2013; Dias et al., 2016).
  • a foremost drawback is encountered by filamentous growth forms of the fungi causing several cultivation challenges, while scaling up an integration process at the existing sugar to ethanol facilities.
  • the broth viscosity caused by the filamentous nature of the fungi negatively affects the mixing and aeration of the culture; mycelial clumps can wrap around impellers; all of which can lead to a decrease in production efficiency and bioreactor performance (Gibbs et al., 2000, Critical Reviews in Biotechnology, 20(1), 17-48).
