The biodegradation of hydrocarbon pollutants in open systems is limited by the availability of a utilizable nitrogen source. This limitation can be overcome by using uric acid. Enrichment cultures grown on crude oil-uric acid media yielded mixed and pure cultures that degraded petroleum. In a simulated open system, uric acid bound to crude oil and was available for bacterial growth and petroleum biodegradation.
开放系统中烃类污染物的生物降解受到可利用氮源可用性的限制。使用尿酸可以克服这一限制。在原油 - 尿酸培养基上生长的富集培养物产生了能够降解石油的混合培养物和纯培养物。在模拟开放系统中,与原油结合的尿酸可用于细菌生长和石油生物降解。
