Decoding lactic acid bacteria genes: What secrets does the super-large genome of Lactiplantibacillus plantarum hide?
Lactobacillus is one of our common probiotics, among which Lactiplantibacillus plantarum (formerly known as Lactobacillus plantarum) is particularly eye-catching.This bacteria is widely present in fermented foods and plant matter. Its excellent adaptability and its huge genome make it a major research focus in the microbiology community.This article will explore the biological properties, genome and its potential health benefits of L. plantarum.
Bio Characteristics
Lactipantibacillus plantarum is a Gram-positive, rod-shaped bacteria with a relatively tough survivability.According to research, its cells are rod-shaped, with a width of about 0.9–1.2 μm and a length of between 3–8 μm, usually in single, paired or short chains.
Genome Expedition
With the advancement of genome sequencing technology, the genome of L. plantarum contains 3308274 base pairs and has a GC content of 44.45%.This huge genome makes it a valuable model in research, and scientists hope to understand the inherent mechanisms of this excellent microorganism by decoding its genome.
According to the experiment, the number of rRNAs in L. plantarum is 15, while the number of tRNAs is as high as 70, indicating that it has quite abundant transcriptional capabilities.
Metabolic capacity
L. plantarum has the highest metabolic capacity and can grow under various environmental conditions.Not only that, it can also undergo anaerobic fermentation and produce lactic acid, a process that is crucial for the production of many fermented foods.In the absence of oxygen, it can use hydrogen peroxide as a metabolite and eventually produce water, a function that helps it stand out from the competition.
Application Scope
Lactipantibacillus plantarum occupies an important position in the food industry and is commonly found in dairy products, meat and a variety of vegetable fermentation products.Especially in traditional foods such as kimchi, sauerkraut and fermented sausage, it plays an indispensable role.
Health Benefits
The health benefits of L. plantarum cannot be ignored.Research shows that it may help improve gut health, enhance intestinal barriers, and regulate microbial balance in the gut.Its antioxidant activity is very effective in reducing oxidative pressure in the body.
L. plantarum also has potential applications in the treatment of depression because it can increase the production of brain-derived neurotrophic factors.
Anti-microbial properties
In addition, L. plantarum demonstrates powerful antimicrobial properties that can fight a variety of pathogenic bacteria.This feature gives it an additional advantage in maintaining gut health, especially when facing antibiotic resistance issues.
Research prospects
With in-depth research on the L. plantarum genome, scientists believe that more potential applications will be discovered in the future to deepen our understanding of the gut microbiome.
Conclusion
In summary, Lactipantibacillus plantarum is a highly adaptable lactic acid bacteria. Its wide range of health benefits and its application in the food industry have formed an attractive research field.However, in the face of this huge benefit, what deeper secrets can we explore from it in the future?
