Microbial electrochemical system for continuous culture, sampling and real-time detection

Abstract

The invention provides a microbial electrochemical system for continuous culture, sampling and real-time detection. The microbial electrochemical system comprises a culture medium container, a peristaltic pump, a culture reactor, a gas cabinet, an exhaust and ventilation system, a computer and an electrochemical workstation. The microbial electrochemical system has the beneficial effects that the system comprises three pairs of parallel culture reaction chambers, and completely parallel contrast can be realized in electrical stimulation tests; continuous culture can be independently performed in the six culture reaction chambers, and different flow velocities and different electrode surface shear forces can be provided; gas-liquid closeness and chemical and biological pollution isolation are kept for a long time; culture solution sampling and electrode surface sampling are realized in an experimental process; with widely adaptive interfaces and modular design, a specific electrode or other parts can be conveniently transformed and loaded according to experimental requirements; the microbial electrochemical system mainly aims at microbes from ocean and is suitable for analysis of multiple biological samples comprising environmental samples and pure culture samples.

Description

technical field [0001] The invention relates to the field of microbial electrochemical technology and culture technology, in particular to a microbial electrochemical system for continuous culture, sampling and real-time detection for research on deep-sea microorganisms. Background technique [0002] Microbial fuel cell technology can convert the energy contained in organic matter in sewage into electrical energy and collect it. Using microbial electrochemical reactions to develop fuel cells and treat sewage has great potential; at the same time, using electrochemical methods to study microbial metabolic processes and microbial-environment interactions On the other hand, the ocean, as a pool of natural resources that is not well understood, has great potential for research and development. The study of marine-derived microorganisms plays an important role in explaining the mechanism of microorganism-environment interaction and developing new natural resources. However, most ...

Problems solved by technology

However, most of the equipment schemes that have been published or made public so far are based on traditional chemical research, and the research scope is relatively single. It is difficult to apply to the applicability of multiple types of biological samples, continuous culture, sampling in experiments and real-time parameters in the research of microbial enrichment from marine sources. The comprehensive requirements of detection and other functions have become a major obstacle in the research and application of marine microbial electrochemistry
