The invention discloses a preparation method of a nano-silver composite antibacterial agent. The invention is characterized in that the nano-silver composite antibacterial agent is formed by combining a nano-silver solution and an organic antibacterial agent which have synergistic effect and adduction effect according to a certain ratio. The structure and performance of the antibacterial agent after combination are stable, and the antibacterial agent has more rapid, efficient and broad-spectrum antibacterial performance. The minimal inhibitory concentration (MIC) of the antibacterial agent for inhibiting escherichia coli, Enterobacter hormaechei, staphylococcus aureus, bacillus subtilis, Rhodotorula mucilaginosa, penicillium and Aspergillus niger is only 1-10 microgram / ml. The preparation method of the nano-silver composite antibacterial agent is characterized in that the nano-silver in the nano-silver composite antibacterial agent has monodispersity and there is no agglomeration phenomenon. The preparation method has advantages of ingenious conception, simple experimental operation, high operationality and short period, and is suitable for large-scale production.

The invention discloses a microbial flora for treating high-salt industrial wastewater and aims to screen and compound functional florae and verify the application effects on the basis of the characteristics that high-salt wastewater is high in salt content, high in chromaticity, high in COD, low in BOD and poor in biochemical property and contains complicated contaminants. Through isolation, screening and acclimatization, an active flora is obtained, the active flora has the capability of tolerating 18% high-salt wastewater and can be applied to biochemical treatment on high-salt pickling wastewater; according to the components and the proportion of the flora, relevant strains are purchased from the China General Microbiological Culture Collection Center and used for simulating the flora components of the acclimatized microbial flora, that is, enterobacter hormaechei, bacillusmegatherium, chromohalobacterjaponicas, halomonasxianhensis, chryseobacteriumindoltheticum and clostridiumsporogenes are compounded in a quantity ratio of 2:2:1:1:1:1, a relatively remarkable degradation effect is achieved when the compounded microbial flora is used for treating wastewater, COD in high-salt wastewater can be degraded to 1935.62mg / L from 29465mg / L, the COD degradation rate is 93.43%, and an effective technical support is provided for biological treatment on high-salt industrial wastewater which is hard to treat.

The invention discloses enterobacter hormaechei and application of enterobacter hormaechei in preparing antibacterial drugs. The preservation number of enterobacter hormaechei No. 5 is CCTCC No. M2013695. The enterobacter hormaechei No. 5 has antagonism to multiple bacteria, so that the enterobacter hormaechei No. 5 can be used for preparing preparation for preventing and controlling vibrio alginolyticus or preparing assistant hemolysis vibrio preparation; the preparation for preventing and controlling vibrio alginolyticus or the assistant hemolysis vibrio preparation can be used for beneficial microbial preparation to replace chemical medicine, improves water quality, and eliminates vibrio alginolyticus or assistant hemolysis vibrio in an aquatic product cultivation system, so that damage to aquatic product cultivation objects from the vibrio alginolyticus or assistant hemolysis vibrio is prevented, the development of the aquatic product cultivation industry is promoted, aquatic products are prevented from carrying the vibrio alginolyticus or assistant hemolysis vibrio, and health and safety of human beings are ensured.

Process for producing a rhamnolipid produced by Pseudomonas or Enterobacter using andiroba or murumuru seed waste, pertaining to the sector of compounds containing monosaccharide radicals, consists of producing rhamnolipids by a biotechnological process using andiroba or murumuru seed waste, following oil extraction, as a substrate for a Pseudomonas aeruginosa, Enterobacter hormaechei or Enterobacter buriae line cultivated in a bioreactor with a non-dispersive aeration system for reducing foam, producing a rhamnolipid content of 10.5 g / L for Pseudomonas aeruginosa bacteria, in bioreactors carried out in a stirred tank with non-dispersive aeration using microporous membranes, particularly of silicone tubes, which allow oxygen to be supplied by diffusion. This type of aeration allows for various configurations, and in the embodiment of the invention, the porous membrane / tube was internally located in the liquid in the bioreactor in the form of a serpentine, under the following process conditions: pure oxygen with suitable pressure and flow rate to maintain O2 pressure in the bioreactor at 20% during the first 24 hours of the assay and stirring varying from 300 to 700 rpm, using 2 radial impellers and manual adjustment according to the decrease in the concentration of dissolved oxygen. The product produced has features that can be used primarily in the cosmetic industry due to its emulsifying, stability and non toxicity capacities.
