Induced by 4℃ low temperature, Escherichia coli inoculated in water can enter the viable but nonculturable state; in the room temperature, Escherichia coli may keep culturable state for a long period; eutrophic culture media of TSA can produce more bacteria count compared with oligotrophic culture media of PCA; evaluating the bacteria count Escherichia coli in water by plate count method may underestimate the risk of intestinal pathogen contamination.

In this paper, 1554 strains of bacteria were isolated from the soybean rhizophere in the different continuous systems. Those biocontrol bacteria were screened in vitro and in vivo. 6 strains of them had the better control efficacy. They exhibited the different antagonism to the pathogens of soybean root in vitro. The strains 18BR2-2 and 18BR9-1 showed a wide range of antagonism against Fusarium oxysporum, F. avenaoeum, F. solani and Rhizoctonia solani in vitro. The 6 strains exhibited different control efficacy to soybean root rot in greenhouse and in field. In greenhouse, they could decrease the degree of soybean disease significantly, and the control efficacy of 18BR2-2 was the best and can reach 45.90%. In theory, soybean treated by 18BR2-2 may postpone the days of outbreaking of disease for 6 days. The strain 18BR2-2 also promoted the growth of soybean seedling and, raising the soybean height for 11.24%, increasing dry weight for 40.91% and fresh weight for 35.27%.

The fatter mice in Gewirtz's study had been bred to lack a protein known as toll-like receptor 5 (TLR5), which most intestinal cells sprout on their surface. Its job is to recognize and bind to the whiplike flagella that bacteria use to move around. TLR5 acts as a traffic cop for controlling the mass of pathogens living in the intestine; without it, the normally harmless gut bacteria tend to overflourish and expand in number.

Gewirtz 实验中的胖小鼠普遍缺乏一种被称之为 toll 样受体5 (TLR5)的蛋白，这种蛋白是肠上皮细胞表面分泌的， TLR5的作用是识别并结合在肠道细菌的运动器官鞭毛上，在对大多数肠道病原体的控制中， TLR5扮演着交通警察的角色，没有它，一般无害的肠道菌就会异常活跃并且大量繁殖。

This research studied the optimal strain combination through single strain and mixed strains fermentation from Sweet Sorghum juice. The suitable proportion and quantity of inoculation, the optimum nitrogen source and its ratio in the medium were established through mixed fermentation. The optimum pH values, fermentation time and temperature were obtained by L9 (3)3 orthogonal experiment. The optimum mixture of biotechnology fulvic acid, Azotobacter chooroccum, Phospho bacteria and Silicate bacteria were studied.

The purpose of this study is to screen microorganisms with growth inhibition against plant fungal pathogens. The plate-dilution method was used to isolate the bacteria from salt marshes at Dafeng, Jiangsu. The antifungal activity of the bacterial broth filtrates against 5 phytopathogens was determined using mycelial disk method. The antifungal compositions of four active bacteria were analyzed primarily with chromatography techniques. Two hundred and thirty-five aerobic (92) and anaerobic (143) bacterial strains have been isolated from the coast salt marsh and sixty-five strains, of which 39 are aerobic and 26 are anaerobic showed greater than 30% of inhibition rate against the growth of at least one of the phytopathogenic fungi on petri dish.
