This study aims to investigate the co-fermentation process between lactic acid bacteria (LAB) and Saccharomyces cerevisiae in the production of sour beer, with a focus on its impact on product quality, including pH, organic acid content, sugar content, and sensory characteristics. In this experiment, selected LAB strains and S. cerevisiae were utilized under controlled fermentation conditions. The microbial ratio was optimized to enhance growth and the production of key compounds. The findings indicate that co-fermentation significantly reduces pH compared to fermentation with yeast alone. Furthermore, an increase in lactic acid was observed due to sugar consumption by LAB, contributing to the distinctive flavor profile of sour beer.

This study examines the effects of chemical mutagens, ethyl methane sulfonate (EMS) and colchicine in inducing mutations in Chrysanthemum spp. through tissue culture techniques. In vitro cultures of Chrysanthemum were treated with various concentrations of EMS and colchicine to assess their impact on shoot regeneration and mutation frequency. Results indicated that EMS significantly increased phenotypic variability, leading to enhanced flower color and size, while colchicine treatment effectively induced polyploidy, resulting in plants with greater flower size and overall vigor. Morphological assessments, along with genetic analyses using molecular markers, confirmed the mutations associated with these treatments. The integration of chemical mutagenesis with tissue culture presents a promising approach for developing novel Chrysanthemum varieties with improved ornamental traits.
