The present invention relates to: a protein having activity for producing methanol or butanol by oxidizing methane or butanol; a microorganism expressing same; a composition for producing methanol or butanol using same; and a method for producing methanol or butanol, wherein the protein is a self-assembled protein comprising a ferritin monomer fused with an ammonia oxidase active domain having methane oxidation activity, or a butane oxidase active domain having butane oxidation activity.

Provided are methods and compositions for inhibiting seed germination. The methods comprise exposing a seed to a composition comprising one or more enzymes, one or more bacteria, and/or an enzymatic extract, wherein the one or more enzymes, one or more bacteria, and/or the enzymatic extract isolated from one or more bacteria are exposed to seed in a quantity sufficient to inhibit seed germination.

The present invention relates to methods for water treatment. in particular using a novel Thauera species that is capable of removing nitrogen via simultaneous nitrification and denitrification. The novel Thauera species may be further capable of phosphate accumulation in the cells. The invention also relates to an isolated Thauera sp. strain SND5 (accession number: CGMCC 21549). The invention further relates to reactors for use in carrying out the methods as described herein and bioprocesses that are carried out using said reactor.

The present invention relates to a protein including self-assembled ferritin monomers, in which a methane oxidation active domain, and an electron transfer domain including a flavin adenine dinucleotide (FAD)-binding domain are fused, and to: a protein which can oxidize methane by using NADH in vivo as a reducing agent, thus being capable of oxidizing methane to methanol without using a separate reducing agent; a microorganism expressing the same; a composition for producing methanol by using the same; and a method for producing methanol.
