“…16S ribosomal RNA gene sequences were analyzed to characterize the microbial community structure and reveal the CW and YMW co-fermentation conditions-associated changes (Figure 3B). According to the results, the most abundant microorganisms detected in the co-fermentation process were related to the following roles: (i) hydrogen production (Alkaliphilus, Bacillus, Clostridium, Romboutsia, Ruminiclostridium and Sporacetigenium) ( Ferraz Júnior et al, 2013, 2015a, 2015b, Bu et al, 2021 (ii) ethanol-hydrogen coproduction (Hydrogenispora) (Liu et al, 2014); (iii) hydrogen consumption (Oxobacter) (Greening et al, 2019); (iv) lactate production (Enterococcus, Lactobacillus, Lactococcus, Leuconostoc, Romboutsia, Sporolactobacillus and Streptococcus) (Castelló et al, 2020;Ferraz Júnior et al, 2017;Fuess et al, 2018) and (v) caproate production (Caproiciproducens) (Kim et al, 2015). These microorganisms are consistent with fermentative systems studies and coherently related to the metabolites presented in Figure 3A and discussed in subhead 3.6.…”

“…In general terms, fermentation technology comprises a cascade of reactions which are primarily related to the production and consumption of hydrogen, considering a fermentative system using non-sterile mixed cultures (Levin et al, 2004). In that case, high production of hydrogen is associated to the mixture of acetate and butyrate fermentation route end-products whilst its low production is associated to other reduced end-products such as acetone, butanol, ethanol and lactate (Ferraz Júnior, 2013).…”

“…A vinhaça é uma das maiores preocupações ambientais do setor sucroalcooleiro, por se tratar de um resíduo poluente em decorrência das suas características físicoquímicas. Apresenta altas concentrações de matéria orgânica, sólidos suspensos, alta demanda bioquímica de oxigênio (DBO), baixos valores de pH, elevada corrosividade e altas concentrações de potássio, nitrogênio, fósforo e sulfato [25,26,27]. Estas mesmas características fazem com que a vinhaça tenha um alto valor fertilizante, podendo assim ser usada na fertirrigação das lavouras de cana-de-açúcar [25].…”

“…Estas mesmas características fazem com que a vinhaça tenha um alto valor fertilizante, podendo assim ser usada na fertirrigação das lavouras de cana-de-açúcar [25]. Todavia, a fertirrigação deve ser realizada com cautela para não ocasionar outros problemas ambientais, tais como contaminação das águas subterrâneas e do solo levando ao seu empobrecimento, salinização e lixiviação, e impedimento da germinação das sementes [25,26].…”
