A method for the bioremediation of hydrocarbon-contaminated production water through the microbiological process of culturing salt-tolerant bacteria in a high-salt cell culture medium for decontamination. The high-salt cell culture medium contains sodium chloride, sodium sulfate, sodium bicarbonate, calcium chloride, and calcium chloride, along with agar, water, and salt-tolerant bacteria to form broth. Once incubated to form an inoculation mixture, this broth is combined with production water to produce a bacteria-containing liquid mixture, and then treated with production water, bioremediating by propagating the bacteria-containing liquid mixture in the treated production water.

The present disclosure provides a microbiological process for the production of hydroquinone from benzoquinone in a microalgal system. The method is particularly characterized by the extraction of the hydroquinone product at a specific points in the process followed by re- introduction of the benzoquinone substrate into the microalgal system. The said method of the 0 present disclosure allows sustained production of hydroquinone.

Disclosed is a soil N2O emission estimation method that couples microbial explicit simulation and implicit simulation methods, comprising S1: for the study area, using the microbial implicit method to estimate the N2O emission from NH4 + Nitrification to NO2 ‑ S2: Based on the nitrification NH calculated in S1 4，n , estimate the biomass of nitrifying bacteria involved in the nitrification process in the soil; S3: use microbial explicit method to estimate the denitrification process of nitrifying bacteria, which includes: estimating NO2 ‑ The process of denitrification to NO; S4: further estimating the process of denitrification of NO to N2O; and S5: calculating the amount of N2O released based on S1-S4. This method effectively circumvents the problems of implicit simulation's lack of consideration of microbial processes and the difficulty in estimating initial values ​​in explicit simulation, effectively improving the simulation accuracy of soil N2O emissions.

The utility model discloses a biochemical incubator which comprises an outer box body, one side of one end of the outer box body is movably hinged with an outer box door, one end in the outer box body is fixedly connected with an end plate, the center line of the end plate and the center line of the outer box body are on the same vertical plane, one side of the outer box body is fixedly connected with a control panel, and the control panel is fixedly connected with the outer box body. An isolation structure used for isolating the cultivation space is arranged in the outer box body. According to the biochemical incubator, through the arrangement of the partition plate, after the movable baffle is pressed to be separated from one end of the positioning piece in the microorganism cultivation process, the inner box door can be pulled to be opened, so that a culture dish is conveniently placed at the top end of the placing plate in the outer box body, and then the inner box door is closed; the movable baffle is ejected out by the spring and attached to one end of the positioning piece so that the inner box door can be positioned through the positioning piece, the interior of the outer box body can be divided into a plurality of spaces through the multiple sets of partition plates in the outer box body so that separated cultivation can be facilitated, and the problem that the cultivation space cannot be effectively isolated is solved.
