Methods for the reduction of methane production in ruminants
The present disclosure provides methods for reducing methane emissions from a ruminant comprising administering to the ruminant a composition comprising a fungal strain, wherein the fungal strain comprises a vanadium-dependent haloperoxidase (VHPO) such as Curvularia sp. strain 4388 (NMI Accession No. V22/011149). The disclosure also provides a cell or a biologically pure culture of Curvularia sp. strain 4388 (NMI Accession No. V22/011149) or a mutant thereof having all identifying characteristics of the strain.
1. A method for reducing methane emissions from a ruminant,
the method comprising administering to the ruminant bromoform produced by a composition comprising:
bromide, and
a vanadium-dependent haloperoxidase (VHPO) comprising SEQ ID NO: 2;
thereby reducing methane emissions in the ruminant relative to a ruminant not administered bromoform produced by the composition.
2. The method of claim 1 , wherein the VHPO is expressed by a fungal strain belonging to the genus Curvularia.
3. The method of claim 1 , wherein the ruminant is a member of the family Bovidae.
4. The method of claim 3 , wherein the ruminant is Bos taurus.
5. The method of claim 2 , wherein the fungal strain is Curvularia sp. strain 4388 (NMI Accession No. V22/011149).
