Lactobacillus Plantarum Lp45
Lactobacillus plantarum LP45 is a strain designation within the species now classified as Lactiplantibacillus plantarum, sold as a freeze dried probiotic culture concentrate standardised on viable count.
The species is a facultatively heterofermentative rod that carries one of the largest genomes among lactic acid bacteria, giving it the enzymatic range to ferment hexoses, pentoses and a number of plant glycosides that narrower lactobacilli cannot use. That metabolic breadth is why plantarum strains establish themselves in silage, brines, sourdough and the mammalian gut alike. LP45 is one of the isolates commercialised in the Chinese market, characterised at strain level and maintained in a controlled seed bank.
The trade form is an off-white to cream freeze dried powder standardised with maltodextrin and packed under nitrogen. Acid and bile tolerance are good enough that gastric survival does not depend on enteric protection, but the dried powder remains hygroscopic and heat sensitive, so it is dry blended under controlled humidity and held cold.
We source bulk Lactobacillus Plantarum Lp45 from top China manufacturers for our partners. The manufacturer is in Hebei. A smaller requirement can ship in a combined container with other ingredients.

Common Markets Grades
The strain is offered as a freeze dried powder at declared potencies from roughly 100 billion to 300 billion CFU per gram on a maltodextrin carrier, and as a frozen concentrate for direct inoculation of fermented products.
Coated grades applied by fluid bed or spray chilling are traded where the culture must survive tabletting, gastric acid or contact with a moist matrix. The same culture sells as single strain material for strain specific claims and as a component of defined multi-strain blends.
Applications
- Probiotic capsules, tablets and stick packs sold on a declared viable count at end of shelf life
- Fermented milk drinks and drinking yoghurts, co-inoculated alongside a yoghurt culture
- Fermented plant based beverages on oat, soy, rice and nut bases
- Pickled and brined vegetables, where a defined culture replaces reliance on the native flora
- Solid beverage powders and stick packs blended with prebiotic oligosaccharides
- Chewable tablets and gummies using the coated grade to survive compression and gelling heat
- Sourdough and cereal pre-ferments for acidity and aroma development
- Silage inoculants and feed additives for forage preservation and gut flora management

Regulatory Status
In the United States the species is used in food under GRAS status, with strain specific GRAS notifications filed where a strain is intended for a defined food application. Material sold into supplements falls under the dietary supplement framework rather than under a food additive regulation.
In the European Union food cultures are treated as ingredients rather than additives, so no E number applies. The species sits on the EFSA Qualified Presumption of Safety list, which settles safety at species level and leaves strain level questions such as transferable antibiotic resistance genes to the dossier for the individual isolate. Codex recognises starter cultures within its standards for fermented milks.
Manufacturing Process
A working vial is drawn from the strain bank and propagated through seed flasks and seed fermenters into a production fermenter charged with a sterilised medium of fermentable carbohydrate, a protein hydrolysate nitrogen source, yeast extract and mineral salts. Growth runs anaerobically at controlled temperature with alkali dosed continuously to hold pH, because the lactic acid the organism produces would otherwise stop growth long before the achievable cell density is reached.
The harvested broth is concentrated by centrifugation or microfiltration into a cell paste, which is blended with a cryoprotectant such as trehalose, sucrose or skim milk solids to protect the membrane through the phase change. The concentrate is frozen as pellets or as a bulk cake and freeze dried under vacuum at low shelf temperature. The dried cake is milled, standardised to the declared count with maltodextrin, blended for uniformity and packed under nitrogen in foil laminate.
