Spittlebug impacts on sugarcane quality and ethanol production

Abstract: -The objective of this work was to evaluate the impacts of spittlebug (Mahanarva fimbriolata) attack on sugarcane quality and ethanol production. Technological and microbiological parameters of juice and fermentation process were evaluated in ten fermentation cycles and two harvest seasons. Treatments consisted of different spittlebug stalk damage levels: control, with 100% of apparently healthy stalks; medium, with 15% of damaged or dry stalks (DDS); high, with 30% of DDS; and very high, with 60% of DDS.

“…The clarification process reduced the amount of microorganisms in the clarified juice to concentrations below 10 2 CFU/mL. RB92579 had smaller amount of yeast compared to that of RB867515, which is probably associated with its higher amount of phenolic compounds, inhibitors of the yeast metabolism (Ravaneli et al, 2011).…”

“…However, high temperature decreases yeast cell viability, as observed with mash of molasses from 2012/2013 harvest. So, for the 2013/2014 harvest, the correct conduction temperature (32 o C) was used, what helped cell viability to be around 85%, which is the recommended one (Ravaneli et al, 2011). Even at high temperature, mash of sugarcane juice showed appropriate initial and final viability ( Table 2).…”

“…A perda de qualidade da matéria-prima é reconhecidamente um dos principais aspectos responsáveis pela redução da viabilidade de células e brotos de Saccharomyces cerevisiae em fermentações do caldo de cana (GARCIA et al, 2010;RAVANELI et al, 2011).…”
