PRODUCT DESCRIPTION

Lactobacillus plantarum is a widespread member of the genus Lactobacillus, commonly found in many fermented food products as well as anaerobic plant matter. It is also present in saliva. It also has the ability to liquefy gelatin. L. plantarum has one of the largest genomes known among the lactic acid bacteria and is a very flexible and versatile species.

ACID TOLERANCE

Acid resistance of Lactobacillus plantarum HH-LP56 powder was carried out at either pH=2.0 and pH=3.0 for up to 4 hours. The microbial enumeration of Lactobacillus plantarum HH-LP56 should be performed no more frequently than at the initial(as control), 1 hour, 2 hour, and 4 hour time points. The Fig 1 illustrates that Lactobacillus plantarum HH-LP56 can survive at low pH conditions, which means this strain has good acid resistance.

BILE SALT TOLERANCE

Bile salt resistance of Lactobacillus plantarum HH-LP56 powder was carried out at either 0.2% and 0.3% bile salt for up to 4 hours. The microbial enumeration of Lactobacillus plantarum HH-LP56 should be performed no more frequently than at the initial(as control), 1 hour, 2 hour, and 4 hour time points. The Fig 2 illustrates that Lactobacillus plantarum HH-LP56 can survive at high concentration of bile salt, which means this strain has good bile salt resistance.

STORAGE STABILITY

Lactobacillus plantarum HH-LP56 powder were sealed in aluminum foil bag, maintained at -18℃ for 24 months for long-term stability test. The microbial enumeration of Lactobacillus plantarum HH-LP56 should be performed no more frequently than at the initial, 1, 2, 3, 6, 9, 12, 15, 18, 21, 24 month time points. According to Fig 3, the potency of Lactobacillus plantarum HH-LP56 powder was 4.50×10¹¹CFU/g. After a storage period of 24 months, the potency of the powder was 2.82×10¹¹CFU/g. It means that this strain can remain stable for long time if stored at low temperature.
