Resumo(s)
This work aimed to evaluate a sustainable bioethanol production by a laboratorial isolate strain of
Saccharomyces cerevisiae, along with the use of agro-industrial by-products as carbon source. The effect of
several carbon sources and their concentrations was studied using carob pod extract (CPE) and beet molasses
(BM) and compared with glucose and sucrose as conventional carbohydrates at different concentrations, 15, 20
and 30 g/l.No significant difference was found between maximum ethanol production obtained with CPE, BM,
glucose and sucrose fermentations profiles. It was obtained values of 10.65 g/l and 10.5 g/l ethanol, respectively
for sucrose and CPE at 30g/l, which can be improved using higher substrate concentration.
