Vinasses: characterization and treatments

“…Grape is a high sugar content crop and its fermentation and clarification steps in the wine-making process yield vinasses with high organic matter content (bacteria and yeasts, alive or dead, grape and additive proteins) and total nitrogen content (Table 1). However, the total nitrogen content is low in comparison with other raw materials such as sugar beet, Wilkie et al (2000); Salomon and Lora (2009); Cail and Barford (1985a). sugar cane, potato and barley.…”

Anaerobic digestion of vinasse from sugarcane ethanol production in Brazil: Challenges and perspectives

“…Regardless of its origin, the main organic compounds present in sugarcane vinasse reported in the literature consist of organic acids (mainly lactate and acetate), as well as alcohols (mainly glycerol and ethanol) and a minor amount of carbohydrates [14,[54][55][56][57]. Table 3 compiles studies in which vinasse characterization was performed, presenting the main parameters that define its composition according to the fermentation feedstock [47,48,[58][59][60][61][62].…”

“…However, limited information is available when considering only vinasse from sugarcane processing. Table 8 depicts the most significant works regarding vinasse treatment in anaerobic reactors and their experimental results considering only the use of sugarcane as feedstock for ethanol production [48,[58][59][60][94][95][96][97][98][99]. Most of the studies date from the mid-1980s and early 1990s, given that it is difficult to find recent data in the literature about the operation of anaerobic reactors treating sugarcane vinasse.…”
