The invention belongs to the technical field of microorganisms, and relates to a selenium-rich bacillus velezensis with high tolerance and application of the selenium-rich bacillus velezensis. The invention relates to a selenium-rich bacillus velezensis 915-1 with strong tolerance, which is preserved in Guangdong Microbial Culture Collection Center, and the preservation number is (GDMCC No: 64021). The bacillus velezensis 915-1 can effectively inhibit growth of escherichia coli, salmonella and staphylococcus aureus after inoculation as first inoculation culture bacteria, and can be used as probiotics or drugs for colonization in intestinal tracts to play roles in inhibiting pathogenic bacteria and benefiting life. The bacillus velezensis is applied to production of organic selenium. The bacillus velezensis can absorb, convert and utilize sodium selenite, the sodium selenite is enriched into thalli to be converted into organic selenium, the content of the organic selenium is increased along with increase of the number of cells, and the bacillus velezensis can be used for production and preparation of the organic selenium.

The invention relates to the field of microorganisms, in particular to bacillus subtilis, a fungicide and application of the fungicide. The invention discloses a bacillus subtilis strain, which is classified and named as bacillus subtilis, has a strain number of GXGD-YZ-2483, is preserved in Guangdong Microbial Culture Collection Center on March 13, 2025, and has a preservation number of GDMCC No: 66014. The bacillus subtilis can tolerate the high temperature of 70-90 DEG C, has excellent self-heat production performance, and can produce lignin degrading enzymes (laccase, manganese peroxidase and/or lignin peroxidase) and inhibit the growth of pathogenic bacteria (escherichia coli, salmonella, clostridium perfringens and/or aspergillus flavus). When the bacillus subtilis or the microbial inoculum prepared from the bacillus subtilis is used for biologically composting organic wastes, a lignin barrier can be efficiently cracked by secreting a lignin degrading enzyme system, lignin degradation, nitrogen retention and pathogenic bacteria inactivation can be synchronously realized by virtue of high temperature resistance, self-heat production characteristics and enzyme activity stability, the composting period is shortened, and the yield of the organic wastes is improved. The humification quality is obviously improved.

A method of generating a Salmonella free egg is disclosed. The method includes administering a vaccination to a poultry animal that is less than one year old. The method further includes boosting the vaccination of the poultry animal when the poultry animal is between about 50 weeks old and about 60 weeks old, the boosting comprising administering killed virus if the poultry animal molted subsequent to the vaccination, and the boosting comprising administering live virus if the poultry animal did not molt subsequent to the vaccination at the time of boosting.

The invention is directed to immunogenic compositions and method of treatment comprising a peptide or nucleic acid that encodes the peptide that induces an immune response in a mammal that is protective against infection by one or more pathogens. The peptide sequence contains multiple epitopes, wherein at least one epitope is a composite epitope which is a combination of two or more conserved epitopes of the pathogen wherein the amino acid sequence of the composite is not an amino acid sequence of the pathogen. In addition, the invention is directed to vaccines comprising the peptide or nucleic acid that encodes the peptide for treating and preventing an infection in mammals such as animals and humans.
