Nano-sized lactic acid bacterium nEF®

Human-derived lactic acid bacteria with superior in absorption

Nano-sized lactic acid bacterium nEF® is the sterilized lactic acid bacteria which is derived from human (Enterococcus Faecalis). The aggregation of the lactic acid bacteria dispersed during the production of the sterilized lactic acid bacteria and the absorption rate of the lactic acid bacteria is improved by patented nano-processing method.

It contains 5 trillion bacteria per 1gram of product, from which we are able to intake high-quality and high-function with in a small amount of lactic acid bacteria powder.

High concentrated powdered lactic bacteria is produced by the process for sterilization, concentration of only lactic acid bacteria and pulverization after cultivation of the lactic acid bacteria. But during pulverization process, cells of the lactic acid bacteria aggregates and become clumps. When dissolved in to water, it becomes a suspension containing various particle size of clamp of bacterial cells.

Nano-sized lactic acid bacteria is the lactic acid bacteria with which the particle diameter is less than 1 μm (micron) and which is dispersed individually when dissolved in water.

60% of the immune cells in the body are concentrated in small intestine. Nano-sized lactic acid bacteria easily pass through the immune system of Peyer's patches in small intestine, it works on immunomodulatory function through gut immunity.

NK cell activity stimulates by intake of nano-sized lactic acid bacterium nEF

Intake of lactic acid bacteria stimulates natural killer (NK) cell activity of spleen. Moreover intake of nano-sized lactic acid bacterium nEF confirmed the dose-dependent effects on NK cell activity.

Prevention against infection of norovirus for mouse by intake of nano-sized lactic acid bacterium nEF

In order to verify how the difference in "dispersibility" at the process of producing sterilizes lactic acid bacteria affects the effectiveness, biological defense function was investigated by norovirus infection test by the mouse using "non-nano lactic acid bacteria" which was sterilized and dried after cultivation and "nano lactic acid bacteria" which was treated by dispersion process at production.

Test method:

Mice which infected to norovirus are divided into 3 groups (control (distilled water) group, non-nano sized lactic acid bacteria group, nano-sized lactic acid bacteria group) and forcedly orally administered daily for 21 days after infection.

Fecal viral amount and neutralizing antibody value in serum blood 3 weeks after infection were measured by plaque assay.

<Number of virus in the stool>

When the amount of excreted virus is decreased, the risk of infection is decreased accordingly. Nano-sized lactic acid bacteria administered group significantly suppress fecal virus growth at the early stage such as 2 days or 3 days after infection more than non-nano lactic acid bacteria administered group.

nEF decreases norovirus by half

<Neutralizing antibody value in serum blood after infection>

Nano-sized lactic acid bacteria group also showed higher neutralizing antibody values that quantified the function of eliminating the virus.

nEF increases antibody value

Nano-sized lactic acid bacteria superior in absorbability can be expected to improve the more rapid prevention effect by exerting the effect of the lactic acid bacteria sufficiently.

Advantage of Nano-sized lactic acid bacteria nEF® (Patented)

Economy: Large amount of lactic acid bacteria can be ingested at low dose and also cost performance is higher.

Reliability: Evidences are already available as afunctional food material. The number of bacteria in final product can be counted.

Quality: Heated lactic acid bacteria is superior heat resistance, with stable quality.

Preservability: Superior in preservability. (Avoid high temperature and humidity and keep in normal temperature)

Sanitation: No concern for contaminating the production line because it is a sterilized lactic acid bacteria.

Convenience: Heated lactic acid bacteria have almost no taste and odor, so it can be used for various products in a wide range of applications.

Functionality: Immunomodulator/intestinal regulation effect as a biogenics material.
