This invention discloses a culture medium for manganese-oxidizing bacteria suitable for low-carbon source environments in water supply networks and its application. The culture medium is prepared by mixing ferric ammonium citrate, manganese sulfate, ammonium sulfate, sodium chloride, magnesium sulfate, dipotassium hydrogen phosphate, and sodium nitrate, followed by high-temperature and high-pressure sterilization to obtain a culture solution. Manganese sulfate is added to the culture solution to obtain the manganese-oxidizing bacteria culture medium. Manganese-oxidizing bacteria are screened using this culture medium. Cast iron pipe scale is subcultured in the medium to enrich the manganese-oxidizing bacteria culture solution. The enriched manganese-oxidizing bacteria culture solution is diluted and spread onto agar solid medium, and incubated at a constant temperature to obtain manganese-oxidizing bacteria colonies. This invention solves the problem of altered bacterial physiological metabolism caused by high concentrations of added manganese ions, effectively improving bacterial activity and manganese oxidation capacity.

This utility model discloses an automated sampling robot for dust and bacterial colony detection, belonging to the field of automated equipment for environmental monitoring and biological experiments. It includes a cart, a rotating gimbal, a support frame, double support plates, a double limiting structure, and a mechanical gripper clamping system. The first limiting structure uses an arc-shaped plate to press against the box, while the second limiting structure uses an air cushion and a top block to fix the culture dish. The mechanical gripper replaces suction cup gripping, improving stability. The double support plates respectively carry the culture dishes for bacterial and dust detection, and the rotating gimbal allows for switching between workstations, enabling dual sampling of dust and bacteria. The rotation angle of the support plates dynamically adjusts according to the number of culture dishes, supporting fixed-point interval detection. This utility model is adaptable to culture dishes of different sizes, has a high degree of automation, and can precisely capture the dynamics of bacterial and dust colonies, providing data support for multi-dimensional environmental analysis.

The present invention relates to the technical field of soil pollutant treatment, specifically to a method for preparing a bacterial colony composite purifying agent for synergistically treating PAEs and Cd. This method includes steps of preparing a functional bacterial colony, preparing a bacterial colony carrier, and preparing a bacterial colony composite purifying agent. The composite purifying agent designed by the present invention not only has broad degradability for PAEs by domesticating functional bacterial colonies to be cadmium-resistant, but can also overcome the problem that the degradation efficiency of a single functional bacterial strain decreases under heavy metal Cd pollution stress in composite polluted soil. In addition, the composite purifying agent designed by the present invention is modified by mercapto and has excellent immobilization effects on heavy metals such as cadmium, and can achieve the effect of synchronously removing PAEs and Cd in soil under the cooperation of functional bacterial colonies.

The application relates to a colony intelligent recognition and counting method and system based on deep learning, and relates to the field of colony analysis. A physical semantic feature tensor is input into a neural network structure for non-negative mapping processing to generate feature image data and a positive output vector. The positive output vector is taken as a parameter vector to calculate a prediction probability distribution and its concentration. Random uncertainty indexes and cognitive uncertainty indexes are calculated according to the prediction probability distribution and its concentration. Dominant type determination is performed on the random uncertainty indexes and the cognitive uncertainty indexes, and a conflict correction factor is generated. The random uncertainty indexes and the cognitive uncertainty indexes are analyzed to generate first path recognition results and second path recognition results, and a prediction bias and a probability drift are calculated to determine whether the two path recognition results converge on the same category distribution feature. The accuracy of colony category recognition and quantity counting is improved.
