Resumo: The production of propionic acid using skim serum by-products of the dairy industry was investigated, and the influence of inoculum concentration of Propionibacterium freudenreichii PS-1 and its time of inoculation for the production of propionic acid was evaluated using mixed culture of Lactobacillus helveticus and Propionibacterium freudenreichii. Initially, the adjustment of propionic bacteria to higher concentrations of propionic acid was tested and kinetic parameters were determined for growth. A central composite rotational design (CCRD) with 11 experiments was carried out, using different inoculum concentrations of P. freudenreichii, which were added to the cultures of lactic bacteria at different times. The maximum specific growth rate for P. freudenreichii decreased from 0.11 to 0.03 hour-1and the growth time increased from 32h to 100h when concentration of propionic acid in lactate broth increased to 0.25%. The best result for propionic acid production was 3.78 g L-1, inoculating 5.108 CFU mL-1 of propionic bacteria after 6 h. For lactose consumption, the best conditions were inoculum concentration above 5.108 CFU mL-1 and inoculation time of P. freudenreichii after 6 hours. Therefore, it was demonstrated that skimmed whey can be used as a renewable, low-cost raw material for propionic acid production by mixed culture.

Inicialmente, foi testada adaptação das bactérias propiônicas a diferentes concentrações de ácido propiônico e foram determinados parâmetros cinéticos de crescimento. Em seguida, foi feito delineamento composto central rotacional (DCCR) com 11 ensaios, usando diversas concentrações de inóculo de P. freudenreichii adicionados em diferentes tempos ao meio com bactéria lática. A velocidade específica máxima de crescimento de P. freudenreichii diminuiu de 0,11 para 0,03 h-1 e o tempo de crescimento aumentou de 32 para 100h aumentando-se a concentração de ácido propiônico em caldo lactato para 0,25% m v-1. O melhor resultado de ácido propiônico foi 3,78 g L-1, usando concentração de bactérias propiônicas de 5.108 UFC mL-1, inoculadas após 4h. Para consumo de lactose, as melhores condições foram concentração de inóculo acima de 5.108 UFC mL-1 e tempo de inoculação de P. freudenreichii após 6h. Comprovou-se que o soro desnatado pode ser usado como matéria prima renovável e econômica para a produção de ácido propiônico por cultura mista.Universidade Estadual de Maringá2018-11-19T12:46:20Z2018-11-19T12:46:20Z2017info:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/articleapplication/pdfNGOME, M.
