Abstract
Zearalenone (ZEN) is a widely distributed mycotoxin that frequently contaminates crops and animal feed. Our previous studies showed that a new strain, Stappia sp. WLB 29 with a 97.47% of similarity to Stappia indica B106T, isolated from the soil samples in the rhizosphere of the crops in Xinjiang, was capable of effectively degrading ZEN in minimal medium. In this study, we determined the complete genomic sequence of the Stappia sp. WLB 29 (Genbank accession number: JALBGD000000000; BioProject ID in GenBank is PRJNA814005). The total length of all sequences was 4,745,415 bp with a GC content of 67.08%. Moreover, the genome-wide analysis showed the presence of laccase- and peroxiredoxin-encoding genes in Stappia sp. WLB 29, which may be associated with ZEN degradation. The genome sequence of Stappia sp. WLB 29 reported here will serve as a reference for comparative genomic studies of ZEN degradation in the feed and food industry.
