7 results about "ENTEROBACTER HORMAECHEI" patented technology

The present application belongs to the field of microbial technology, and particularly relates to a bacteriophage preparation for controlling foodborne enterobacter and application thereof, wherein the bacteriophage preparation comprises any one or several of bacteriophage PhiEAS1, bacteriophage PhiEHO11, bacteriophage PhiEHO14 and bacteriophage PhiECL22. The four bacteriophages provided by the present application can be used alone or combined into a bacteriophage cocktail, and the influence of the bacteriophage preparation on enterobacter in different ecologies and environments is explored through bacteriophage cocktail therapy. The results show that the bacteriophage preparation exhibits significant bacteriostatic activity on various food substrates contaminated by Enterobacter hormaechei, such as lettuce, pork, milk, cherry tomato and the like; in an animal model, intraperitoneal injection of the bacteriophage preparation can effectively prevent and treat bacteremia caused by Enterobacter hormaechei, and shows potential as an anti-Enterobacter hormaechei biological control agent.

According to the scheme, the recombinant macrolide enzyme and the preparation method and application thereof are provided, the amino acid sequence of the recombinant macrolide enzyme is shown as SEQ ID NO.1, and the recombinant macrolide enzyme is obtained by site-directed mutagenesis of an erythromycin esterase family protein sequence derived from enterobacter hormaechei; the mutation sites are as follows: the 44 glutamic acid is mutated into asparagine, the 55 tyrosine is mutated into proline, the 153 proline is mutated into alanine, and the 219 serine is mutated into glutamic acid, so that the specific macrolide lactonase which is efficient, stable, easy to prepare on a large scale and more suitable for environmental requirements is prepared, and macrolide antibiotic pollution is removed; and the method has good economic benefits and practical values.

The invention discloses enterobacter hormaechei Z2 and application thereof in improving soybean biomass, and belongs to the technical field of microorganisms. The collection number of the enterobacter hormaechei Z2 disclosed by the invention is CGMCC (China General Microbiological Culture Collection Center) No.36028. The enterobacter hormaechei Z2 disclosed by the invention has relatively strong organophosphorus decomposing capability, and can promote the formation of a biological membrane and generate an iron carrier; and the soybean biomass is improved.

The invention provides enterobacter hormaechei and application thereof. The preservation number of the Enterobacter hormaechei is CGMCC (China General Microbiological Culture Collection Center) NO. 33974, and the preservation number of the Enterobacter hormaechei is CGMCC NO. By adopting the enterobacter hormaechei disclosed by the invention, the conventional chemical components of cigar tobacco leaves are remarkably changed, the contents of total sugar, reducing sugar and total nitrogen are remarkably reduced, the total amount of aroma substances is remarkably increased and is 2.2 times that of aroma substances before aroma-producing bacteria are added, and the types of the aroma substances are increased, including acid, ketone, alcohol, hydrocarbon, aldehyde and furan compounds. The strain M9 has a remarkable effect of improving the aroma amount and the aroma quality of cigar tobacco leaves, and provides a theoretical basis and a technical support for application of a microbial aroma enhancement technology in the tobacco industry as a new microbial aroma enhancement resource.
