Most antibiotics are derived from the soil, but their catabolism there, which is necessary to close the antibiotic carbon cycle, remains uncharacterized. We report the first draft genome sequences of soil identified for subsisting solely on β-lactams as their carbon sources. The genomes encode multiple β-lactamases, although their antibiotic catabolic pathways remain enigmatic.
大多数抗生素来源于土壤,但其在土壤中的分解代谢(这是闭合抗生素碳循环所必需的)仍未得到充分研究。我们报告了首个仅以β-内酰胺类抗生素作为碳源的土壤微生物的基因组草图序列。这些基因组编码多种β-内酰胺酶,尽管它们的抗生素分解代谢途径仍不明确。
