The present invention relates to a crystal form I of tenvermectin B, which can be characterized by X-ray powder diffraction (XRPD) pattern, Infrared (IR) absorption spectrum, Differential scanning calorimetry (DSC) thermogram and the like. Meanwhile, the present invention also relates to a method for preparing the crystal form I of tenvermectin B and a use thereof.

Crystal form of tenvermectin B, preparation method therefor, and use thereof

The invention provides a construction method of spinosad heterologous expression strain, a spinosad heterologous expression strain obtained by the method and use thereof in preparing spinosad. The method utilizes a plurality of homologous recombination to replace the erythromycin synthetic gene cluster ofwith the spinosad synthetic gene cluster and the rhamnose synthetic gene cluster, such that theproduces spinosad.

Spinosad heterologous expression strain and construction method thereof and use

Disclosed are a frame assembly structure of a wooden doors and windows and a corner assembly method. The window includes, at least, a window frame or a casement window frame mainly formed by joining adjacent profile frame strips via a corner assembler on adjacent connecting end surfaces. The connecting end surfaces of two adjacent profile frame strips are respectively configured to be cross sections of 0&#xb0; to 180&#xb0;. A positioning notch of the corner assembler is at least provided on the cross sections. Two half corner assemblers of the corner assemblers are respectively embedded and fixed into the positioning notches on the adjacent cross sections. The two half corner assemblers are connected by an intermediate fastening piece and a fastening bolt to form a complete corner assembler, and the two adjacent profile frame strips are connected tightly and fixedly. The frame assembly structure is easy to assemble.

Assembly frame structure of wooden casement window and corner assembly method

The present invention relates to a recombinant microorganism expressing avermectin or analogs thereof and construction method thereof, and also relates to a method of producing avermectin or analogs thereof using the recombinant microorganism, and avermectin or analogs thereof obtained using the method. In addition, the present invention further relates to uses of the avermectin or analogs thereof as insecticides. Using the recombinant microorganism of the present invention to produce avermectin or analogs thereof has numerous advantages, for example comprising at least one of the following: good stability, high yield, simple process, environmentally friendly, and greatly saving of production costs.

Recombinant microorganism expressing avermectin analogue and use thereof

A sixteen-membered macrolide compound and use thereof, the compound structure being represented in formula (I), wherein R is CHor CH. The present compound has a wide range of application in the preparation of chemicals for preventing and controlling insect pests and mites of agriculture and forestry. 

Sixteen-membered macrolide compound and applications thereof

Ceramic packing with channels for thermal and catalytic beds

A ceramic packing element is formed from a stack of ceramic plates having parallel ribs forming parallel grooves therebetween. The grooves are closed into channels by the surf ace of an opposed plate. The ribs may engage the end surfaces of ribs on an adjacent space or may be interleaved with the ribs of an opposed plate to form smaller channels. The plates are adhered to each other by firing a stack of plates in the green state or wrapping film or bands around a stack of pre-fired plates. The elements may be preassembled into larger units before placement in a column by wrapping metal bands around an assembly of elements.
