The present application relates to a compositions and methods comprising or expressing a MOMO30 protein derived from Momordica balsamina. The MOMO30 protein is about 30 kDa in size, binds coronavirus S protein, is stable after being autoclaved at 120° C. for 30 min, resists proteolytic cleavage by trypsin, exhibits mannose-sensitive binding to coronavirus spike (S) protein, exhibits hemagglutinin and chitinase activity, is capable of activating and stimulating T cell proliferation, is capable of preventing infection by a coronavirus or alleviating symptoms in coronavirus infected patients and comprises the amino acid sequence of SEQ ID NO: 1. The MOMO30 protein and/or a nucleic acid encoding the same may be used in methods for preventing or treating viral infections by coronaviruses and others.

The present invention discloses a recombinant modified extracellular chitinase having an amino acid sequence set forth in SEQ ID NO. 4 or SEQ ID NO. 5 prepared by substituting two tyrosine (Y) residues with histidine (H) in the native chitinase of Brevibacillus laterosporus LAK 1210. The modified chitinase represents an advancement as it has improved thermal stability, wider optimum pH range, high efficacy, improved solubility and low toxicity. The present invention also provides compositions and improved methods for producing and purifying the recombinant modified chitinase by chitin affinity chromatography and chitin adsorption affinity chromatography using shrimp shell and crab shell, for large scale production at low cost. The modified chitinase has wide range of applications including prevention, treatment or modulation of phytopathogenic infection in a plant or a plant part.

The present invention is directed to a pesticide composition comprising at least two proteins selected from the group consisting of: CrylIa10, Cry2Abl, Cry9Eal, and the amino-acid sequence set forth in SEQ ID NO: 6. Further provided are the nucleic acid construct comprising a nucleic-acid sequence encoding CrylIa10, Cry2Abl, Cry9Eal, and the amino-acid sequence set forth in SEQ ID NO: 6, and a method of controlling a pest, comprising contacting the pest with an effective amount of the pesticide composition disclosed herein.

The present application relates to a compositions and methods comprising or expressing a HEVAR or MOMO30 protein derived from Momordica balsamina. The HEVAR or MOMO30 protein and/or a nucleic acid encoding the same may be used in methods for treating or preventing viral infections, particularly those caused by coronaviruses, such as SARS-CoV-2.

A method of extracting and isolating psilocybin and/or psilocin from psilocybin fungi includes forming a mixture of the fungi, an extraction solution, and a chitinase capable of digesting chitin present in the fungi. Solids can be filtered from the mixture to yield an extract including psilocybin and/or psilocin. The extract can be purified to isolate the psilocybin and/or psilocin.

The present invention relates to a strain for producing chitinase and application thereof. The class of the strain is named Streptomyces diastaticus CS1801 and the preservation number thereof is CCTCC NO: M2018263. The Streptomyces diastaticus CS1801 of the present invention is derived from naturally fermented prawn paste. By fermentation of prawns, the enzyme activity of the chitosan is as high as 57.3 U/L and the content of chitooligosaccharides is 0.58 mol/L. The present invention provides a new method for producing chitooligosaccharides and has a good application prospect.

Recombinant DNA techniques are used to produce oleaginous recombinant cells that produce triglyceride oils having desired fatty acid profiles and regiospecific or stereospecific profiles. Genes manipulated include those encoding stearoyl-ACP desaturase, delta 12 fatty acid desaturase, acyl-ACP thioesterase, ketoacyl-ACP synthase, and lysophosphatidic acid acyltransferase. The oil produced can have enhanced oxidative or thermal stability, or can be useful as a frying oil, shortening, roll-in shortening, tempering fat, cocoa butter replacement, as a lubricant, or as a feedstock for various chemical processes. The fatty acid profile can be enriched in midchain profiles or the oil can be enriched in triglycerides of the saturated-unsaturated-saturated type.

The subject invention provides methods of producing advantageous microbes and/or by-products using a modified form of solid-state fermentation, or matrix fermentation. In particular, the methods utilize foodstuff mixed with liquid nutrient medium to produce a three-dimensional scaffold substrate having ample surface area on which the microbes can grow. The methods can be used to cultivate yeasts, fungi and bacteria at high concentrations without susceptibility to total contamination. The subject invention can be used in remote locations and can be transported with ease.

The present application relates to a compositions and methods comprising or expressing a HEVAR or MOMO30 protein derived from Momordica balsamina. The HEVAR or MOMO30 protein and/or a nucleic acid encoding the same may be used in methods for treating or preventing viral infections, particularly those caused by coronaviruses, such as SARS-CoV-2.

There is disclosed a peptide with mucolytic activity, The peptide comprising an amino acid sequence having at least 60% sequence identity to the amino add sequence defined in SEQ ID NO: 1, but does not consist of the amino sequence defined in SEQ ID NO: 2.
