preparation example Construction
[0052] Further preferably, the preparation method of the aquatic plant endophyte composition comprises the following steps:
[0053] (1) Collection of aquatic plants;
[0054] (2) Mixing the above-mentioned raw materials and fermenting to obtain an aquatic plant endophyte composition.
[0055] In some embodiments, the picking method of the aquatic plants is: picking the green parts of the aquatic plants before sunrise.
[0056] In some embodiments, the specific operation of the step (2) is as follows: adding sucrose to the aquatic plants under aseptic conditions and stirring evenly, then adding non-iodized salt and brine and stirring until the aquatic plants have juice flowing out, under sealed conditions Incubate at a constant temperature and filter to obtain the liquid fraction.
[0057] Further, the conditions of the constant temperature culture are: constant temperature culture at 30 to 40° C. for 5 to 10 days.
[0058] A fourth aspect of the present disclosure provides...
Embodiment 1
[0064] The bacterial strain model used in the present embodiment and the purchase method are as follows:
[0065] The yeast is commercial yeast, and the brand is Angel high temperature resistant liquor yeast;
[0066] Lactobacillus Lactobacillus plantarum CICC 21790, purchased from Industrial Microorganisms Collection Center;
[0067] Bacillus natto is Bacillus natto, purchased from Cangzhou Laisen Biotechnology Co., Ltd.;
[0068] Bacillus subtilis is Bacillus subtilis subsp. subtilis GIM1.372, purchased from the Guangdong Provincial Microbial Culture Collection Center;
[0069] Bacillus licheniformis (Bacillus licheniformis) GIM1.626, purchased from Guangdong Provincial Microbial Culture Collection Center;
[0070] Photosynthetic Bacteria (PSB for short), purchased from Cangzhou Laisen Biotechnology Co., Ltd.;
[0071] The actinomycetes were Nocardia (Nocardia) GIM1.381, purchased from the Guangdong Provincial Microbial Culture Collection Center;
[0072] Nitrifying bact...
Embodiment 2
[0077] In this example, the effect of the compound bacterial agent in treating black and odorous river silt is described with the results of the pilot test of the ecological restoration of the black and odorous river silt in the Xiwangmen River in Rongcheng, Shandong. The tofu brine used in this embodiment is Angel Baizhuan brine tofu coagulant.
[0078] 1. Location and scope
[0079] like Figure 5 It is located within 100m under the bridge, and the average width of the river is about 50m. In order to emphasize the contrast effect of governance, the center line of the river is used as the boundary, and half of the river silt on the west side is selected for in-situ restoration.
[0080] 2. Pilot scheme
[0081] (1) Closing the gate to control tide, isolation and management
[0082] In order to avoid the impact of seawater tide on the construction, it is necessary to close the gate before construction to block the sea tide; due to the thick silt in the river, the silt aroun...
