Chlorella pyrenoidosa, biological environment restoration liquid prepared therefrom and application of chlorella pyrenoidos

The invention discloses chlorella pyrenoidosa, biological environment restoration liquid prepared therefrom and application of the chlorella pyrenoidosa, relates to a green alga active cell biologicalrestoration liquid, and aims to provide chlorella for environment restoration and application of the chlorella. The chlorella is the Chlorella pyrenoidosa ZXL X, and the depositary authority is ChinaCenter for Type Culture Collection, the depositary address is Wuhan University, Wuhan, Hubei Province, the depositary date is November 18, 2020, and the depositary number is CCTCC NO: M 2020760. Thechlorella pyrenoidosa is used for improving the soil environment, promoting crop yield increase and improving crop quality. The restoration liquid is prepared by the following steps: culturing chlorella pyrenoidosa with a nutrient solution to an exponential growth phase and mixing the cultured chlorella pyrenoidosa with an alginate solution; extruding the mixed solution to a calcium chloride solution to obtain globules; and mixing with the globules with a working solution to obtain the biological environment restoration liquid. The environment restoration liquid provided by the invention is high in content value, does not produce drug residues, and can realize agricultural sustainable development.

Glyphosate concentration detection method based on Raman signals of chlorella pyrenoidosa

The invention discloses a glyphosate concentration detection method based on Raman signals of chlorella pyrenoidosa. The glyphosate concentration detection method comprises the following steps: (1) acquiring Raman spectrum information of chlorella pyrenoidosa samples from water bodies with glyphosate of different concentration, and preprocessing the Raman spectrum information; (2) establishing a prediction model by virtue of alternating least square according to the concentration of glyphosate in the water bodies and the preprocessed Raman spectrum information; and (3) acquiring Raman spectrum information of a to-be-measured chlorella pyrenoidosa sample, processing the Raman spectrum information of the to-be-measured chlorella pyrenoidosa sample by virtue of a multivariate curve resolution method, and inputting the processed Raman spectrum information into the prediction model, thereby obtaining the concentration of glyphosate in a glyphosate water body from which the to-be-detected chlorella pyrenoidosa sample is collected. According to the detection method, the water sample does not need to be subjected to complicated preprocessing and chemical analysis, so that the operation steps are greatly simplified, and the detection time is shortened.
