摘要
从受油烟废气污染严重的土壤中分离、筛选出一株具有较强的降解油酸能力的ZFS-1菌株。最佳生长条件为:碳源2.33 g/dL、氮源0.53 g/dL、摇床转速180 r/min。最佳的降解条件:温度33℃,pH 7.5,接种体积分数为10%,油酸质量浓度0.79 mg/mL,18 h后油酸的降解率达到85%以上。
A stain with strong oleic acid degradating ability, ZFS-1, was isolated from the soil severely contaminated by exhaust smoke or gas. The optimal growth condition was as follow: carbon content of 2.33%, nitrogen content of 0.53% and shaking speed of 180 r/min. Under the condition of temperature 33℃, pH 7. 5 ,incubation amount 10% and oleic acid 0.79 mg/mL,after 18 hours cultivation the oleic acid degradation rate of up to 85% could be reached.
