Non-culturable microorganism screening system based on generative adversarial network principle

Abstract

The invention discloses a non-culturable microorganism screening system based on a generative adversarial network principle, which performs data processing on non-culturable microorganisms to obtain metabolic network and genome data, inputs the metabolic network and genome data into a model shown in figure 1 to obtain a series of culture medium components, and performs automatic sampling, plate sealing, cultivation and detection to obtain a cultivation result. The results are input into a training network to improve a parameter optimization model. Data distribution difference exists between non-culturable microorganisms and culturable microorganisms, the system utilizes migration learning and based on the generative adversarial network principle, the non-culturable microorganisms are takenas a target domain data set, the culturable microorganism data set is taken as a source domain data set, the characteristic space distribution difference between a source domain and a target domain is reduced through a discriminator principle of the generative adversarial network, knowledge migration from the culturable microorganisms to the non-culturable microorganisms is completed, the automation system is enabled to be more complete, and the purpose of improving the accuracy of predicting a culture medium formula is achieved.

Description

technical field [0001] The present invention relates to technical fields such as bioinformatics, artificial intelligence, biological control technology, automatic control, etc., and specifically relates to a non-culturable microorganism screening system based on the principle of generative confrontation network. Background technique [0002] As we all know, various microorganisms exist in every corner of the world. It provides many conveniences to humans, such as penicillin, which is a metabolite of actinomycetes, can inhibit the growth of pathogenic bacteria, and lactic acid bacteria ferment carbohydrates into lactic acid, which is a good helper for making yogurt; but it also brings certain benefits to humans. Trouble, such as loss of breeding, water pollution, moldy food, etc. At present, less than 1% of all microorganisms can be cultivated in the laboratory, and very few can be cultivated industrially, which hinders people's understanding of the use of beneficial bacteri...
