Unlabelled: Spent coffee grounds (SCG) are commercial waste that are still rich in numerous valuable ingredients and can be further processed into useful products such as coffee oil, antioxidant extract, lactic acid, and lignin. The challenge and innovation is to develop the SCG processing technology, maximizing the use of raw material and minimizing the use of other resources within the sequential process. The presented research is focused on the aspect of biotechnological production of lactic acid from SCG by using the Lacticaseibacillus rhamnosus strain isolated from the environment.

Fish were fed for 14 days with four different diets, each treatment being carried out in triplicate. In control group, fish were fed dry commercial starter feed Aller Performa 2 (Aller Aqua, Denmark).

- This study focuses on the fermentation process of sourdough, where a mix of flour and water develops a natural community of bacteria and yeasts, enhancing bread quality.* -
- Researchers found that lactic acid bacteria (LAB) significantly outnumbered yeasts in the sourdough ecosystem, with Lactobacillus becoming the dominant bacteria after 72 hours of fermentation.* -
- The findings help to understand the microbial diversity in sourdough made from different wholemeal flours, which could be useful for creating specific starter cultures for better bread production.*
Introduction: Immune-potentiating functions of strains in the common carp were evaluated.
Material And Methods: Fourteen days of feeding fish dry diet supplemented with the bacteria provided parameters of nonspecific humoral immunity (lysozyme, ceruloplasmin, γ-globulin, total protein levels, and serum bactericidal activity) and cellular immunity (pinocytosis, respiratory burst activity, and potential killing activity of organ phagocytes), as well as the proliferative response of organ lymphocytes stimulated with mitogens. The resistance of fish to infection with was also determined.
