The invention relates to a method for manufacturing glassine paper having a basis weight of less than 50 g / m2, wherein an optimal combination of BSKP, BHKP and BCTMP is used to adjust the properties of the fiber furnish. In glassine papers with very low basis weight the formation of the paper web upon paper manufacturing may be controlled by means of the fiber furnish optimization, which can be used to produce exceptionally thin glassine paper without downgauging and without adverse effects to other paper properties, which would prevent the use of the glassine paper as substrate layer in a release liner. Thus glassine paper with a moderate share of BCTMP in the fiber furnish may be produced, that has quality characteristics of the paper sufficient for use as a substrate layer of an industrial release liner.

This invention relates to a method for rapidly screening filamentous fungi that produce high levels of triglycerides and polyunsaturated fatty acids, belonging to the field of microbial technology. The method employs a two-stage screening strategy of "resistance primary screening – fluorescence secondary screening." In the primary screening stage, strains with strong lipid synthesis capabilities are initially screened by adding a combination of phytocyanin and quizalofop-p-ethyl inhibitors to the culture medium. In the secondary screening stage, cellophane culture technology and Nile red fluorescence staining are combined to quantitatively assess the triglyceride content of the colonies, achieving rapid and non-destructive screening. This method is simple to operate, highly efficient, and shows a significant positive correlation between fluorescence intensity and triglyceride content. It is suitable for mutagenesis breeding and industrial strain selection of oil-producing filamentous fungi such as *Morchella alpineensis*.
