Increasing temperature in recent years poses a substantial influence on fermentation industries and thus, huge cooling systems are required to maintain the optimum temperature leading to additional cost of production. In the present study, simultaneous vinegar fermentation with thermotolerant yeast (Kluyveromyces marxianus DMKU3) and thermo-adapted acetic acid bacteria (Acetobacter pasteurianus TH3) was performed at 37, 40 and 41°C with 10% initial glucose in shaking and static cultures. The highest ethanol production (4.952±0.02 % v/v) by tropical yeast and the highest acetate production (4.44±0.01 % w/v) was observed at 37 °C when both strains were added together at the beginning of fermentation. Moreover, it was found that higher vinegar production was achieved under shaking culture than the static culture. Moreover, the tropical yeast and the thermoadapted TH3 strains were able to use in simultaneous coconut water vinegar production at 37 and 40 °C successfully with an acetic acid production of 2.53±0.01% (w/v) and 2.34±0.03% (w/v) respectively. Thus, thermotolerant yeast and thermo-adapted bacteria could be successfully used in vinegar fermentation under higher temperature conditions.

Functional constituents of mango flesh include phenolic acids such as gallic, vanillic, syringic, protocatechuic like hydroxybenzoic acid derivatives, and p-coumaric, chlorogenic, ferulic, and caffeic acids like hydroxycinnamic acid derivatives (Burton-Freeman et al. 2017); Flavonoids and other polyphenolic compounds such as catechins, kaempferol, anthocyanins, and tannic acid (Haytowitz et al. 2018;
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
