Problems solved by technology

Normal intestinal flora has many important physiological functions, such as antagonism to passing flora, immune effect on host, detoxification, anti-tumor effect, anti-aging effect and other nutritional effects (such as diabetes, hypertension, high blood pressure, etc.) blood lipids, etc.), but once there is an imbalance of intestinal flora, it is bound to disturb these normal physiological functions

Embodiment Construction

[0026] A strain of probiotics that can promote the secretion of SIgA in the intestinal tract. The probiotics (Lactobacillus plantarum P8) were isolated from kumiss samples collected in China and preserved in the General Microorganisms Collection Center of China Microbiological Cultures Collection Management Committee. No.: CGMCC No.5468, date of deposit: November 18, 2011.

[0027]The method for detecting probiotics that can promote the secretion of SIgA in the intestinal tract is characterized in that it includes the following steps:

[0028] 1. Collection of test samples

[0029] A total of 33 healthy volunteers were recruited in this experiment (see Table 1 for specific information), divided into three groups, youth group (Ygroup, 11 people, 5 males, 6 females), aged 25-29 years, with an average age of 26.2± 1.2 years old; middle-aged group (M group, 12 people, 6 males, 6 females), aged 48-53 years, with an average age of 50.9±1.4; elderly group (E group, 10 people, 5 male...

Abstract

The invention discloses lactobacillus plantarum capable of promoting the secretion of SIgA (Secretory Immunoglobulin A) in an intestinal canal. The lactobacillus plantarum is characterized by being separated from koumiss samples collected in China and is collected at China General Microbiological Culture Collection Center of Microbiological Culture Management Committee, the collection number is CGMCC No. 5468, and the collection date is 18th, November 2011. The invention also discloses a detecting method of the lactobacillus plantarum.

Description

technical field [0001] The invention relates to a probiotic strain-Lactobacillus plantarum P8 that can promote the secretion of SIgA in the intestinal tract. Background technique [0002] A wide variety of microorganisms live in the gastrointestinal tract of healthy people. These microorganisms are called intestinal flora. Compared with passing flora, most of the intestinal flora are long-term resident microorganisms. 10 14 Left and right, and are composed of fairly fixed bacteria, and regularly settle in some specific parts of the body. The intestinal flora, the intestinal flora, the host and the environment are always in a state of dynamic balance, forming an interdependent and mutually restrictive system, so when the body's defense function is normal, it is beneficial and harmless to the human body. Normal intestinal flora has many important physiological functions, such as antagonism to passing flora, immune effect on host, detoxification, anti-tumor effect, anti-aging...
