Disclosed are novel nitrilated psilocybin derivative compounds and pharmaceutical and recreational drug formulations containing the same. The compounds may be produced by reacting a reactant psilocybin derivative with a nitrile-group containing compound.

A microbial composition for improving the conditions in animal farms comprising: a slow-releasing carrier base having a first predetermined percentage by weight (w/w %); and a mixture of microorganisms identified in a 16S rRNA gene sequence so that the composition is capable of denitrification, feces decomposition, and hydrogen sulfide (H.sub.2S) oxidation.

The present invention relates to the analysis of complex single cell sequencing libraries. Disclosed are methods for enrichment of library members based on the presence of cell-of origin barcodes to identify and concentrate DNA that is relevant to interesting cells or components that would be expensive or difficult to study otherwise. Also, disclosed are methods of capturing cDNA library molecules by use of CRISPR systems, hybridization or PCR. The present invention allows for identifying the properties of rare cells in single cell RNA-seq data and accurately profile them through clustering approaches. Further information on transcript abundances from subpopulations of single cells can be analyzed at a lower sequencing effort. The methods also allow for linking TCR alpha and beta chains at the single cell level.

Provided are novel piperazic acid containing peptide compound stereoisomer, solvate, or pharmaceutically acceptable salt thereof, method of preparing the same, and use thereof. The peptide compound, stereoisomer, solvate, or pharmaceutically acceptable salt thereof has activities of anticancer, anti-metastasis, and growth inhibition of resistant tumors, and thus may be used to prevent or treat various cancers or metastases of cancer.

Provided are a novel tricyclic dilactone compound, a strain producing the same, a method of producing the tricyclic dilactone compound, and use of the tricyclic dilactone compound. The tricyclic dilactone compound has activity of inhibiting aggregation of amyloid-beta and tau proteins, activity of inhibiting apoptosis, and anti-inflammation activity, and thus may be used to prevent, treat, or improve various neurodegenerative brain diseases including Alzheimer's disease and cognitive impairment.

The invention relates to a metabolic enzyme-disrupted aerobic strain and a method for culturing the strain. The present invention provides, for example, a culture comprising a culture medium that has been cultured under an aerobic condition, wherein the culture medium contains an aerobe, wherein the aerobe has a disrupted gene encoding a metabolic enzyme of glycolysis selected from the group consisting of the metabolic enzymes of glycolysis except hexokinase, thereby suppressing metabolism from a carbon source (e.g., glucose) to the TCA cycle in the aerobe.

A method for improving the production of Streptomyces polyketide compounds is provided. The method greatly improves the capability of the Streptomyces polyketide compounds by strengthening a triacylglycerol decomposition pathway in Streptomyces during the stationary phase. A method for switching the primary metabolism of Streptomyces to the secondary metabolism, Streptomyces producing polyketide compounds, and use thereof are also provided.

The present invention addresses the issues of finding a novel mutation effective for the improvement of transglutaminase and providing a highly useful modified transglutaminase. Disclosed is a highly useful modified transglutaminase having an amino acid substitution that results in an increase of high temperature reactivity or a lowering in pH stability in a weakly acidic region.

This disclosure describes compositions and methods for enhanced production of enduracidin in genetically engineered strains of Streptomyces fungicidicus. In particular, the present disclosure describes the genetic manipulation of regulatory genes orf24 and orf18 associated with the enduracidin (enramycin) biosynthesis gene cluster from Streptomyces fungicidicus to generate vector constructs and recombinant strains producing greater yields of enduracidin.

The present invention provides a novel daptomycin-producing Streptomyces strain and use thereof, the strain is a subspecies of streptomyces griseus, named Streptomyces griseus L340, and the preservation number is CGMCC17921. The genetic character and fermentation unit of the strain provided by the present invention are relatively stable, the culture and fermentation conditions are suitable for industrial production of daptomycin, and the interference of pigment in later separation and purification is eliminated. The secondary metabolite daptomycin is obtained through fermentation of the Streptomyces provided by the present invention, which has the advantages of no interference of pigment accumulation, cleaner metabolic spectrum and thus is obviously superior in later separation and purification.
