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

Abstract

A provided microbial electrochemical system for continuous culture, sampling and real-time detection comprises a medium container, a peristaltic pump, a culture reactor, a gas closet, an air pumping-exchanging system, a computer and an electrochemical workstation. The beneficial effects comprise that the microbial electrochemical system comprises three reaction chambers for parallel culture, so that complete parallel comparison can be realized in electrical stimulation experiments; six culture reaction chambers can independently perform continuous culture, different flow speed and different electrode-surface shearing force are provided; the microbial electrochemical system can keep long-term gas-liquid seal and isolate chemical and biological pollutions; nutrient-solution sampling and electrode-surface sampling can be realized in an experiment process; widely-applicable interfaces and modularization design are provided, specific electrodes and other parts can be conveniently refitted or mounted according to experiment demands; and the microbial electrochemical system mainly aims at microbes coming from sea, and is applicable to analysis on multiple biological samples containing environment samples and purely-cultured 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
