Introduction | The selected high-quality Lactobacillus delbrueckii subsp. bulgaricus is processed into freeze-dried powder by a freeze-drying process. The ingredients contain strain and cryoprotectant. The product is in powder form, without visible impurities, and the color is white to light yellow. Lactobacillus delbrueckii subsp. bulgaricus is a Gram-positive rod that may appear long and filamentous. It is non-motile and does not form spores. It is also non-pathogenic. It is regarded as aciduric or acidophilic, and it is anaerobic. Lactobacillus delbrueckii subsp. bulgaricus is commonly used alongside Streptococcus thermophilus as a starter for making yogurt. |
Alternative Names | Lactobacillus delbrueckii subsp. bulgaricus; Lactobacillus bulgaricus; L. d. subsp. bulgaricus; L. delbrueckii |
Lactobacillus delbrueckii subsp. bulgaricus powder should be added at the beginning of the fermentation process. It is important to rehydrate the powder in sterile water or a growth medium before adding it to the fermentation substrate. Ensure consistent mixing to achieve uniform distribution.
Yes, Lactobacillus delbrueckii subsp. bulgaricus powder can be used in co-culture systems with other probiotics. It is essential to optimize the growth conditions to support the growth of all involved microorganisms. Monitor the interactions and adjust the conditions as needed to achieve the desired outcomes.
Critical parameters include pH, temperature, bacterial cell viability, and concentration. Regular monitoring ensures that the experimental conditions remain optimal and that the powder retains its functionality throughout the study.
Recommended methods for analyzing the activity include plate counting to determine colony-forming units (CFUs), measuring acid production, and using molecular techniques such as qPCR to quantify gene expression levels. These methods help in assessing the viability and functional performance of the powder.
