The patent application relates to isolated polypeptides that specifically cleave non-glycosidic ether bonds between lignins or derivatives thereof and saccharides, and to cDNAs encoding the polypeptides. The patent application also relates to nucleic acid constructs, expression vectors and host cells comprising the cDNAs, as well as methods of producing and using the isolated polypeptides for treating pulp and biomass to increase soluble saccharide yield and enrich lignin fractions.

A genome-editing complex for modifying a target polynucleotide comprising a recombinant β helical protein linked to either one or more molecules of a genome-editing system or a plasmid encoding for one or more molecules of a genome-editing system, wherein the β helical protein length is in the range of from 5 nm to 25 nm, and width is in the range of from 1 nm to 5 nm.

Antipathogenic polypeptides and related compounds and compositions that display antipathogenic activity, antifungal activity (i.e., act as fungicides), antialgal activity (i.e., act as algaecides), and/or enzymatic activity against chitin (i.e., degrade chitin) and/or polyglucuronic acid (i.e., degrade the polyglucuronic acid) are described. These antipathogenic polypeptides, as well the related compounds and compositions disclosed herein, can be used in protecting/treating products, including but not limited to agricultural products and water bodies (including drinking water), from pathogens, including fungi and algae, as well as generating pathogen-resistant products (particularly fungi-resistant and/or algae-resistant products).

Alginate lyase activity is exhibited by the amino acid sequences (polypeptides) shown in SEQ ID No:1 and SEQ ID No:2. These polypeptides and their homology equivalents are used to produce 4-deoxy-L-erythro-5-hexoseulose uronic acid (DEH) by contacting the polypeptide(s) with an alginate containing a uronic acid moiety and holding the mixture of the alginate and the polypeptide(s) at a temperature at which alginate lyase activity is exhibited.

Compositions for removing air pollutants from the air are provided. These compositions can be sprayed on a variety of surfaces to remove air pollutants such as volatile organic compounds (VOCs) from the environment, and are suitable for use in human dwellings.

A method of promoting a desired oral microbiota to treat an inflammation condition related to an allergic reaction in a subject in need of such treatment including providing a preformulated edible composition including an amino acid containing ingredient comprising L-arginine, the composition configured to be present as individual molecules of L-arginine within an oral cavity of the subject; removing a biofilm from surfaces within an oral cavity including exposing the biofilm to a biofilm degrading enzyme; wherein during or following removal of the biofilm, the composition is provided contained and at least partially dissolved within an oral cavity of the subject for a period of at least from about 30 seconds to about an hour on a daily basis comprising at least one day to promote an increased concentration of selected oral microbiota, the selected microbiota including Veillonella and Streptococcus.

Some embodiments are directed to a novel ulvan lyase, a nucleic acid sequence coding for said enzyme, a vector comprising said coding sequence, a method for manufacturing said ulvan lyase, and a method for producing ulvan oligosaccharides with biological activity using said enzyme
