A seabed anti-pollution microbial film in-situ cultivation device

Abstract

The invention relates to an in-situ culture device, in particular to a seabed anti-pollution microbial film in-situ culture device. Including the base, the upper end of the base is provided with a guide rod and a double-headed screw that are parallel to each other, the front bar and the rear bar are perpendicular to the guide rod and the double-ended screw, and the two ends are respectively connected to the guide rod through a sliding bush and a screw nut and a double-ended lead screw; one end of the double-ended lead screw is connected to the output shaft of the waterproof motor, and the sample cylinder includes a cylindrical sampling cylinder, which is arranged around the front horizontal bar, the rear horizontal bar guide rod and the double-ended screw rod. In the space formed, the front bar and the rear bar at both ends of the sampling cylinder are respectively provided with a front end cover and a rear end cover. There are two through holes on the cylinder body and the end cover of the pressure balance cylinder, one of which is an exhaust hole, and the other is connected to the other end of the pressure-resistant hose through a stop valve. The invention effectively avoids contamination of the sample by impurities and bacteria, and improves the purity of the sample.

Description

technical field [0001] The invention relates to an in-situ culture device, in particular to a seabed anti-pollution microbial film in-situ culture device. Background technique [0002] The ocean area occupies about 71% of the total surface area of ​​the earth. It is estimated that there are more than 10 million biological species in the ocean, which has great biodiversity. In the past 50 years, humans have discovered more than 20,000 natural products through the cultivation and research of marine microorganisms, many of which have novel and unique structures, and have been found to have anti-tumor, anti-cell aging, and anti-bacterial / viral activities. For related drugs development is of great significance. The research and development of marine microbial diversity and its natural product resources are receiving more and more attention from all over the world. Due to the small amount of microorganisms in ordinary seawater samples, the efficiency of direct sampling is low. ...

Problems solved by technology

In order to continuously enrich microorganisms, it is necessary to place the plate in an open seawater environment for a period of time. In order to meet this requirement, the existing devices are often designed as an open structure, which leads to unavoidable damage to the plate during the lowering and recovery process. Contact with seawater at other depths, so that the sample is mixed with impurities and bacteria, reducing the purity of the sample
