Target Introduction
Introduction
Lactobacillus species are normal flora of the human mouth, gastrointestinal tract, and female genital tract, where they produce lactic acid and competitively inhibit pathogenic organisms. Lactobacillus are small, slender, nonmotile, Gram-positive bacilli in chains. Immature colonies appear smooth, convex, and translucent. Some species of Lactobacillus used commonly as probiotics. They are most commonly used for diarrhea, including infectious diarrhea and diarrhea in people taking antibiotics. Some people also use lactobacillus for general digestion problems, irritable bowel syndrome; IBS, colic in infants, and many other conditions that involve the stomach and bowel.

FAQs Customer Reviews Related Products
What are the optimal growth conditions for Lactobacillus crispatus; 243 in laboratory settings?
Lactobacillus crispatus; 243 grows best in anaerobic or microaerophilic conditions, at 37°C in MRS broth with a pH of 5.5-6.0, favoring slightly acidic environments.
What is the recommended storage method for maintaining the viability of Lactobacillus crispatus; 243?
To maintain the viability of Lactobacillus crispatus; 243, it is essential to store it at -80°C if frozen, or below 4°C for short-term use in a liquid culture medium. Avoid repeated freeze-thaw cycles, as this can lead to significant loss in bacterial viability. Proper storage ensures the strain remains potent for downstream research applications.
What downstream applications can Lactobacillus crispatus; 243 be used for in scientific research?
Lactobacillus crispatus; 243 is used in research on vaginal health, bacterial vaginosis prevention, and microbiome studies, with applications in probiotic therapy and pathogen defense.
How is the viability of Lactobacillus crispatus; 243 quantified in research experiments?
Viability is typically assessed through colony-forming units (CFU) counting, where the bacterial culture is serially diluted and plated on selective agar to estimate live bacterial counts. Alternative methods such as flow cytometry or qPCR targeting Lactobacillus crispatus-specific genes can also be used to determine the bacterial load in complex microbial communities.
What challenges are associated with scaling up Lactobacillus crispatus; 243 for industrial applications?
Scaling up Lactobacillus crispatus; 243 from lab-scale to industrial production involves optimizing fermentation conditions, ensuring high cell viability, and maintaining consistent product quality. Common challenges include maintaining bacterial stability during production, storage, and delivery in commercial probiotic formulations. Addressing these issues is critical for effective live biotherapeutic product development.
