● What Is Lactobacillus Plantarum ?
In the long history of symbiosis between humans and microorganisms, Lactobacillus plantarum stands out for its strong adaptability and versatility. This probiotic, which is widely found in naturally fermented foods, has been deeply developed through modern biotechnology in recent years and is moving from the traditional fermentation field to diversified application scenarios such as medicine, agriculture, and environmental protection, becoming the focus of the global health industry.
Lactobacillus plantarum is a Gram-positive rod-shaped bacterium, arranged singly or in chains, which produces more than 85% lactic acid through homotypic fermentation, has the ability to produce acetic acid, and has a wide pH tolerance range (3.0-9.0). It has abundant glycosidases, proteases, and bile salt hydrolases, which can degrade polysaccharides, proteins, and cholesterol, and promote nutrient absorption. It can grow under anoxic or facultative anaerobic conditions, has a fast acid production rate (pH drops below 4.0 in 24 hours), and inhibits the colonization of pathogens.
● What Are The Benefits Of Lactobacillus Plantarum ?
Based on multi-omics research and clinical trials, the efficacy system of Lactobacillus plantarum has formed a complete chain:
1. Intestinal Health Management
Bacterial flora regulation: By competitively inhibiting pathogenic bacteria and stimulating mucus protein secretion, increasing the ratio of Firmicutes/Bacteroidetes, and improving intestinal problems such as constipation and diarrhea.
Barrier strengthening: Lactobacillus Plantarum Promote the production of short-chain fatty acids (SCFAs), repair the intestinal mucosal barrier, and reduce serum D-lactic acid and endotoxin levels.
2. Metabolic Regulation
Cholesterol regulation: Lactobacillus Plantarum can reduce serum total cholesterol (by 7%) and low-density lipoprotein (LDL) through bile salt hydrolase activity, while increasing high-density lipoprotein (HDL).
Blood sugar control: Fermentation products (such as 2,4,6-trihydroxybenzaldehyde) inhibit α-glucosidase activity, reduce glucose absorption, and activate the AMPK pathway to improve insulin resistance.
3. Immunity And Disease Resistance
Immune activation: stimulate the secretion of Th1 cytokines such as IL-12 and IFN-γ, balance Th1/Th2 immune response, and reduce the risk of allergic diseases.
Anti-inflammatory and antioxidant: remove DPPH free radicals, upregulate the activity of antioxidant enzymes such as SOD and CAT, and reduce oxidative stress damage.
4. Environmental And Industrial Applications
Heavy metal degradation: secrete extracellular polysaccharides to bind heavy metal ions such as lead and cadmium, and use them for contaminated soil remediation.
Microplastic management: reduce the accumulation of nanoplastics in the liver and intestines through adsorption and metabolism, and alleviate ecological toxicity
● What Are The Application Of Lactobacillus Plantarum ?
1. Food Industry
Fermented products: As the core strain of yogurt, kimchi, and sausage, it improves flavor and shelf life.
Functional food: Develop cholesterol-lowering milk powder and blood sugar-control probiotic granules.
2. Animal Husbandry And Agriculture
Feed additives: Adding 10^6 CFU/kg can reduce ammonia nitrogen emissions by 30% and improve feed conversion rate
Plant growth promotion: Enhance crop disease resistance through rhizosphere colonization and reduce pesticide use.
3. Medical And Health
Clinical preparations: Lactobacillus Plantarum is used to treat irritable bowel syndrome (IBS) and antibiotic-associated diarrhea, with a clinical efficacy of over 80%.
New therapies: Combined with traditional Chinese medicine (such as Chinese date seeds and gardenia) to improve insomnia through the “gut-brain axis”, the sleep time is extended by 48%.
4. Environmental Protection And Energy
Bioremediation: Degrade pollutants such as petroleum hydrocarbons and polycyclic aromatic hydrocarbons, and is used in oilfield wastewater treatment.
Biofuels: Participate in cellulosic ethanol fermentation to increase yield by 15%-20%
