A method including contacting a contaminated aqueous stream including water and one or more contaminants with a coated porous substrate including a porous substrate coated with a hydrophilic and oleophobic coating to provide a treated water including water that passes through the coated porous substrate, wherein a level of the one or more contaminants in the treated water is less than the level of the one or more contaminants in the contaminated aqueous stream, and wherein the contaminated aqueous stream includes a waste or catchment stream from a hydrocarbon (HC) exploration, production, transportation, or storage facility, a chemical production, transportation, or storage facility, or a combination thereof.

The present invention aims at improving the purification of sewage in water treatment systems, by the use of enzymes. A filter comprising enzymes and a method for producing said filter are provided, as well as the use of said filter, a module system (10) for comprising said filter, and use of said module system.

Fusion proteins containing a targeting sequence, an exosporium protein, or an exosporium protein fragment that targets the fusion protein to the exosporium of a Bacillus cereus family member are provided. Recombinant Bacillus cereus family members expressing such fusion proteins are also provided. Genetically inactivated Bacillus cereus family members and recombinant Bacillus cereus family members that overexpress exosporium proteins are also provided. Seeds coated with the recombinant Bacillus cereus family members and methods for using the recombinant Bacillus cereus family members (e.g., for stimulating plant growth) are also provided. Various modifications of the recombinant Bacillus cereus family members that express the fusion proteins are further provided. Fusion proteins comprising a spore coat protein and a protein or peptide of interest, recombinant bacteria that express such fusion proteins, seeds coated with such recombinant bacteria, and methods for using such recombinant bacteria (e.g., for stimulating plant growth) are also provided.

A water purification chamber is provided. In one embodiment, a system comprises a purification chamber comprising a selective adsorbent activated carbon fiber fabric including one or more selective functional groups that bind arsenic.

The present invention provides a process for the treatment of sewage sludge with enzymes, which process comprises treating a sewage sludge resulting from the treatment of municipal or industrial waste water with a composition comprising a fermentation supernatant product from a Saccharomyces cerevisiae culture and a non-ionic surfactant, wherein said fermentation supernatant product is free of active enzymes, at conditions suitable for generating said active enzymes from said sewage sludge in situ.

The present invention relates to methods for preventing, removing, reducing, or disrupting biofilm present on a surface, comprising contacting the surface with an alpha-amylase derived from a bacterium.

The present disclosure relates to methods and systems for converting biomass into biofuels and biochemicals. In particular, the present disclosure relates to methods and systems for converting biomass comprising lignocellulosic material into biofuels and biochemicals, such as those comprising fatty acid esters, that contribute to reduction of greenhouse gas emissions.

An apparatus for refractory organics conversion into biogas includes an anaerobic digester configured to be fed with organic material comprising refractory organics and to generate biogas and a digestate comprising at least a part of the refractory organics, wherein the apparatus comprises a device for a controlled partial oxidation of the refractory organics comprising an inlet configured to be fed with refractory organics and means configured to control the residence time of the refractory organics within the device for a controlled partial oxidation, so as to partially degrade refractory organics. A method for refractory organics conversion into biogas carried out using such an apparatus is also provided.

A process and system for reducing biochemical oxygen demand (BOD) of food and beverage processing effluents.

The present disclosure relates to a porous liquid or a porous liquid enzyme that includes a high surface area solid and a liquid film substantially covering the high surface area solid. The porous liquid or porous liquid enzyme may be contacted with a fluid that is immiscible with the liquid film such that a liquid-fluid interface is formed. The liquid film may facilitate mass transfer of a substance or substrate across the liquid-fluid interface. The present disclosure also provides methods of performing liquid-based extractions and enzymatic reactions utilizing the porous liquid or porous liquid enzyme of the present disclosure.
