Microbiological and physicochemical evaluations of juice extracted from different parts of sugar cane stalks from three varieties cultivated under organic management

Abstract: IntroductionThe term "cachaça" is usually applied to a beverage obtained by the fermentation of sugar cane juice after distillation. The cachaça production is a complex microbial process characterized by the occurrence of different yeast species with predominance of Saccharomyces cerevisiae (MORAIS et al, 1997;PATARO et al., 2000;SCHWAN et al., 2001). Basically, this beverage is processed by two distinct forms, industrial and artisanal. In the industrial segment, the process is conducted in big and medium-size… Show more

“…If S. pombe has a tendency to occur in detectable cell densities late in the fermentation process, this could explain why it was not detected in several other investigations on cachaça fermentations (Morais et al 1997 ; Silva et al 2009 ), too. Additionally, Martini et al ( 2010 ) did not find any Schizosaccharomyces yeasts in sugar cane juice and it was not detected in or on sugar cane itself (Khunnamwong et al 2018 ; Nasanit et al 2015 ; Srisuk et al 2019 ). This suggests that S. pombe is present in low cell densities at the beginning of the fermentation process.…”

“…and Streptomyces spp. (Klaushofer, Clarke, Rein, & Mauch, 1998;Lucca, Kitchen, Clarke, & Goynes, 1992;Martini, Correia-Margarido, & Ceccato-Antonini, 2010;Nunez & Colmer, 1968). The composition of the population of microorganisms is closely linked to the sugar content and pH of sugar cane.…”

“…This result may be attributed to the yeast composition of the juice, which is known to vary along the sugarcane maturation. Saccharomyces yeasts are more resistant to PMB than non-Saccharomyces yeasts (Divol et al, 2012;Bassi, Paraluppi, Reis, & Ceccato-Antonini, 2015) and the proportion between Saccharomyces and non-Saccharomyces in the sugarcane juice oscillates according to the sugarcane maturation (Martini, Margarido, & Ceccato-Antonini, 2010).The sugarcane juice has a diversity of bacteria and fungi that can compete with the starter yeast S. cerevisiae and affect the fermentative yield. Genera as Candida, Debaryomyces, Hanseniaspora, Meyerozyma, Wickerhamiella and Zygosaccharomyces were observed to constitute 11.9% of the yeasts present in the sugarcane stalks, and Candida represents the major fraction (Souza et al, 2016).…”

“…Two characteristics of the sugarcane juice should be highlighted to explain the high doses of PMB required to achieve a microbial logarithmic reduction of at least one log cycle, that is the pH of the juice (around 5.0-5.5) and the presence of sugars like glucose (Martini et al, 2010).The efficiency of PMB decreases with the increase in pH (Divol et al, 2012). Oliva-Neto and Yokoya (2001) verified that the minimum inhibitory concentration of sodium sulphite to lactic bacteria increased around 15 times when the pH of the medium varied from 4.5 to 6.5.…”
