Embodiment Construction

[0025] The present invention will be further described in detail below in conjunction with the accompanying drawings, so that those skilled in the art can implement it with reference to the description.

[0026] like figure 1 As shown, the present invention provides an in-situ enrichment device for marine microorganisms, including an open culture cabin 110 , a closed culture cabin 120 , an environmental monitoring sensor 130 and a solid culture medium 140 .

[0027] Wherein, the open culture chamber 110 includes an open chamber body 111 and an upper cover 112, and a solid culture medium 140 is placed in the open chamber body 111, and the solid culture medium 140 contains nutrients required for the growth of microorganisms. An opening is arranged above the open cabin body 111, and an upper cover 112 is closed on the opening above the open cabin body 111, and the upper cover 112 can be opened vertically upwards driven by the driving device, thereby closing the upper opening of t...

Abstract

The invention discloses a marine microorganism in-situ enrichment device which comprises an open culture cabin, a closed culture cabin and three sets of environment monitoring sensors. The open culture cabin comprises an open cabin body and an upper cover. The upper cover can be perpendicularly opened upwards under the drive of a driving device so as to open the open cabin body. The closed culture cabin comprises a closed cabin body provided with a water inlet and a water outlet. A peristaltic pump is arranged in the closed cabin body, so that exchange between the interior of the closed cabin body and external seawater is achieved. The three sets of environment monitoring sensors are located in the open culture cabin, the closed culture cabin and the external environment respectively and used for detecting environment parameters of the PH value, dissolved oxygen, turbidity, methane and the like of the environment. According to the marine microorganism in-situ enrichment device, marine microorganism in-situ enrichment is achieved, the environment of the microorganism in-situ enrichment process is the same as the microorganism growth environment, the survival adaptability of microorganisms is improved, and microorganism death or activity lowering caused by environment changes is avoided.

Description

technical field [0001] The invention relates to the technical field of microorganism enrichment, in particular to an in-situ enrichment device for marine microorganisms. Background technique [0002] Marine microorganisms are all microorganisms that normally live in ocean water, including bacteria, fungi, and phages. Among them, marine bacteria are an important link in the marine ecosystem. Compared with land, the marine environment is characterized by high salinity, high pressure, low temperature and dilute nutrients. Therefore, marine microorganisms have long-term adaptation to the complex marine environment and have their unique characteristics. Nutrients in seawater are relatively thin, and some marine bacteria require growth on a nutrient-poor medium. On a generally nutrient-rich medium, some bacteria die quickly after forming colonies for the first time, and some bacteria cannot form colonies at all. This type of marine bacteria is poisoned to death due to the exces...
