    Abstract: Antifreeze proteins having an ice-binding site, such as those derived from the Marinomonas primoryensis bacterium, may be used in additive compositions, fluid compositions, and methods for depressing the freezing point of the fluid compositions. The fluid composition may include the antifreeze protein and a base fluid, such as drilling fluids, servicing fluids, production fluids, completion fluids, injection fluids, refinery fluids, and combinations thereof.

    Abstract: Corrosion and/or calcium scale deposition on a surface in contact with corrosion forming components and/or scale forming components within a subterranean formation may be decreased, prevented, and/or inhibited by contacting the surface with at least one protein. The protein(s) may be or include, but is not limited to, at least one aspein protein, at least one aspolin protein, at least one dentine protein, at least one DRICH-1 protein, at least one nacrein protein, at least one SMDT-1 protein, derivatives thereof, fragments thereof, mimetics thereof, and combinations thereof. The surface may be or include, but is not limited to a metal surface, a plastic surface, a ceramic surface, a painted surface, a coated surface, and combinations thereof.

    Abstract: Corrosive effects arising during well treatment applications are inhibited and/or prevented by introducing into the well composition containing a corrosion inhibitor of a biosurfactant selected from glycolipids (other than sophorolipids and mannosylerythritol lipids), phospholipids; polyol lipids; lipoproteins, lipopeptides, ornithine lipids, carbohydrate-lipids, neutral lipids, aminoacid lipids, exolipids, liposan; siderolipids, protein polyamines diglycosyl diglycerides, fimbriae, saponified triglycerides and fatty acids. The composition may also contain a corrosion inhibitor intensifier.

    Abstract: Cellulose may be converted into simple sugars such as glucose by contacting the cellulose with a compound effective to catalytically cleave the ether bonds of the cellulose. The compound may be a vitamin, a porphyrin, flavins, pyridoxal-containing molecules, and/or a compound containing at least one ylide functional group. The cellulose may be carboxymethyl cellulose (CMC), which may be made by reacting cellulose with chloroacetic acid and a base such as NaOH. The compound may be vitamins (B1, B2, B6, or B12), phosphonium ylides, sulfonium ylides, sulfoxonium ylides, carbonyl ylides, oxonium ylides, asomethine ylides, iminium ylides, halonium ylides, and combinations thereof. The free glucose may be used for fermentation, converted to a biofuel and for other applications.
