- Taking into account that the composition of the yeast cell wall can vary with respect to different growth conditions, the objective of this study was to determine the influence of additives (EDTA, SDS, NaCl) on the production of yeast biomass, the percentage of cell wall and its composition, in order to obtain β-glucan. The extraction of the cell wall was carried out by an alkaline extraction technique and the study of the composition was carried out using infrared (IR) spectroscopy. The production of biomass and cell wall was variable, depending on the strain and the treatments studied. The IR spectra of each cell wall showed 3 characteristic regions of the wall (polysaccharides, proteins and lipids). In addition, it was possible to determine the chemical groups corresponding to beta glucans and amides I and II corresponding to chitin. The glucans content, and the β-glucan/chitin ratio in particular, varied with the yeast strain and with the additive studied. Future studies must be performed to extract the β-glucans and determine their concentration in each cell wall The optimization of the production of cell wall and its components from yeast strains will allow its application in obtaining β-glucans for the food, pharmacological and cosmetic industries.
Considerando que a composição da parede celular da levedura pode variar em função de diferentes condições de crescimento, o objetivo deste trabalho foi determinar a influência dos aditivos (EDTA, SDS, NaCl) na produção de biomassa de levedura, a porcentagem de parede celular e sua composição, a fim de obter β-glucano. A extração da parede celular foi realizada pela técnica de extração alcalina e o estudo da composição por espectroscopia de infravermelho (IV). A produção de biomassa e parede celular foi variável, dependendo da linhagem e dos tratamentos estudados. Os espectros de IV de cada parede celular mostraram três regiões características da parede (polissacarídeos, proteínas e lipídeos). Além disso, foi possível determinar os grupos químicos correspondentes à β-glucano e as amidas I e II correspondentes à quitina. O teor de glucanos, e a razão β-glucano/quitina em particular, variaram com a cepa de levedura e com o aditivo estudado. Estudos futuros devem ser realizados para extrair os β-glucanos e determinar sua concentração em cada parede celular. A otimização da produção da parede celular e seus componentes a partir de cepas de leveduras permitirá sua aplicação na obtenção de β-glucanos para a indústria alimentícia, farmacológica e cosmética.
