Lactobacillus Plantarum | 7 Important Points

Lactobacillus Plantarum

Lactobacillus Plantarum

The novel L. Plantarum was isolated from silage and MRS agar, and its growth and fermentation patent was determined using a standard method. Many researchers have reported it in vitro application. Read on to learn more about this probiotic and the benefits it offers. We also discuss the benefits of this probiotic to humans. Read on to understand more regarding the many uses it has in human health. Let’s begin.


The tannase enzyme is highly conserved among tannases from different species. Its insertions, however, differ. These differences may reflect distinct roles in biological processes. This enzyme is responsible for the fermentation of lactic acid. It is a possible nominee for use in the dietary supplement industry. The biosynthesis of lactic acid may also provide a source of energy.

The tannase gene was studied in 29 strains of L. Plantarum. Chromosome DNA was isolated, and PCR amplification was performed to determine whether both genes were present. The tannase gene was present in both RM35 and CECT 749. The amino acid sequences showed that tanALp contains one of the two genes. This finding supports the hypothesis that tannase genes are ubiquitous in L. Plantarum.

TanALp contained four copies and was found to be present in strains of L. Plantarum. Its putative signal peptide suggested that this gene may be extracellular. The tannase activity was also detected in some strains. This gene encodes a protein that can bind to tannic acid, a gall tannin that cannot pass into cells.

peptidoglycan hydrolases

The lactobacillus Plantarum peptidase Lyta and LytB have different roles during the cell cycle, but their combined PG hydrolytic activities are important for growth. Both are essential for septal positioning in addition to their role in cell cycle progression. The LytA and LytB proteins are responsible for the cleavage of most of the gD-Glu-Meso-DAP bonds.

The bacterial cell wall is an important target for antibacterial agents. The peptidoglycan hydrolases found in Lactobacillus Plantarum are also a potential target. These proteins may act as alternative antibiotics. However, these enzymes have not yet been identified in any other organism. The researchers hope to use the results to find new antibiotics that will have better effects against pathogenic bacteria.

The LPC protein is a reversible peptidoglycan hydrolase that participates in tannin degradation. LPC is dependent on the UbiX-like protein LpdB. The LpdB gene is unknown, but they cluster closely in L. Plantarum. Both proteins are co-transcribed and greatly enhance LpdC’s decarboxylation activity. Inactivating MreBCD reduces LpdC activity.


This enzyme, a major component of L. plantarum’s cell wall, plays a role in autolysis. The major autolysin of L. Plantarum, Acm2, also serves a morphogenic role. When the enzyme is absent, the cells grow at a delayed rate, are impaired in viability, and show severe structural defects of the cell wall. This enzyme can also be utilized to produce more robust starter strains.

In addition to degrading casein, Lb. Plantarum PFC231 has been implicated in contributing to cheese’s aroma. The enzymes released during autolysis may degrade proteins and amino acids and contribute to cheese’s ripening. While the specific mechanisms are not known, the results of this study are promising for dairy producers. Nonetheless, further studies are essential to restrict the potential for using white-brined cheese.

Genetic analyses of L. Plantarum strains have shown that they share the same gene clustering system. However, they differ in their ability to autolyze cell walls. Genetic analysis has revealed that WCFS1 and J51 possess the same plan composition. Although the gene content of each strain is variable, the overall phenotype of L. Plantarum strains is low. The strains are closely related, making it difficult to separate them from closely related species.

mucosal immune response

There are several strains of Lactobacillus Plantarum, and these isolates vary in the number of TLR-binding dendritic cells they produce and their effects on a mucosal immune response. The current study focused on the effect of three L. Plantarum strains on mucosal immunity and intestinal barrier function, and the results were consistent with earlier findings. In addition, the study found that healthy volunteers’ small intestine permeability increased after administration of indomethacin. Additionally, the strain TIFN101 had profound effects on mucosal gene transcription.

Two strains of Lactobacillus Plantarum have distinct patterns of plantaricin biosynthesis. While both lack plantaricin biosynthesis clusters, both strains lack large regions necessary for sugar metabolism. This lack of genes may enhance the immune effects of L. Plantarum. Further, these strains exhibit similar patterns of bacterial growth and colonization. Interestingly, the TIFN101 strain has an enhanced ability to induce mucosal immune responses to mucosal inflammation and infection.

LAB has several unique properties that make them a viable delivery vehicle for therapeutic and vaccine applications. Moreover, the C-repeat region of Streptococcus pyogenes (Sp) protein was expressed in L. lactis in vitro and triggered an immune response in animals. In addition to vaccine development, LAB has also been used as a delivery vehicle for many different molecules, including antibiotics and therapies for gastrointestinal and allergic diseases.

FE activity

This study was conducted to determine the FE activity of Lactobacillus Plantarum in fermented milk samples. This cultured bacterium has shown good antimicrobial activity against various foodborne pathogens. Several isolates were identified as L. Plantarum through API-50 CHL and 16S rRNA sequencing. Five isolates showed the greatest antibacterial activity.

The CFS and biomass of different isolates of L. Plantarum varied significantly. The CFS activity of L1 and L4 was approximately 6400 to 25600 AU/ml. The maximal CFS activity was reached after 40 h, and it remained constant throughout the subsequent 72 h. These data demonstrate that L. Plantarum is an excellent probiotic for dietary supplementation.

Its antibacterial activity was also demonstrated in the intestine. Its FE activity is attributed to the ability of the bacterium to inhibit the growth of Gram-positive and -negative pathogens. These bacteria were also shown to protect against ROS and promote intestinal barrier function. In addition, some strains exhibit anti-inflammatory and scavenging activities. This type of bacterium is beneficial in the pharmaceutical and food industries, but further research is needed to determine whether it has any prophylactic properties.


To evaluate the potential safety of L. Plantarum in animal feed, the European Commission asked the EFSA FEEDAP Panel to deliver a scientific opinion on the safety of the bacterial species. This bacterial strain is used as a technological additive in animal feed, where it is present at 5.0 x 107 CFU per kg of fresh material. The bacterial species is deemed safe in feed based on a study conducted in 2012.

Several strains of L. Plantarum were studied in randomized controlled trials in patients with IBS. Several of these articles have reduced IBS-related symptoms, including abdominal pain, flatulence, and distension. However, studies of the L. Plantarum UALp-05 strain indicate that it can reduce pain, diarrhea-predominant stool type, and overall quality of life.

Antimicrobial activity was assessed using a combination of different methods. The most efficient method used to assess the antimicrobial activity of L. Plantarum is to sequence 16S rRNA genes. In this way, the strains can be differentiated based on their differences in lactic acid production. There are three main types of L. Plantarum strains: homofermentative, heterofermentative, and acidophilic.

Studies have shown that L. Plantarum strains differ in their ability to bind Cd. This may be due to different amounts of lipoteichoic acid (LTA) in their cell walls. In addition, the LTA content in some strains may have a role in their ability to bind metal ions. In the present study, we analyzed the contrasts in Cd-binding ability between L. Plantarum ATCC8014 and L. casei strains.

The effects of EDS on liver and kidney function were evaluated. This compound increases serum cholesterol and alanine-amino transferase activity and reduces SOD and CAT activity. Co-administration of Lactobacillus Plantarum BJ0021 mitigated the effects of EDS intoxication on these organs. The authors conclude that BJ0021 may inhibit the formation of free radicals, but further studies are required to identify its mechanism of action and whether it affects apoptosis.

While there are no conclusive analyses on the toxicity of a single LAB strain, multiple LAB strains are nonpathogenic and safe for human and animal consumption. The results of these studies are encouraging and support the idea that the lactic acid-producing bacteria may be beneficial for the human gut. This bacteria is a natural part of the intestinal ecosystem and is widely used in many products, including yogurt and baby food.
