Biodegradation has become a popular alternative remediation technology for its economic and ecological advantages. An aerobic bacterium （strain ZW） capable of degrading α-pinene was isolated from a biofilter by a selective enrichment. Based on the 16S rRNA gene analysis and physiochemical properties, this strain was identified as Pseudomonas veronii. Under the optimized condition achieved by the response surface methodology （RSM）, as well as pH 6.82, temperature 26.3℃ and NaC1 concentration 1.36%, almost 100% α-pinene could be removed within 45 hr. Enzymatic biodegradation by the crude intracellular enzyme could be described well by the Michaelis-Menten model in which the maximum degradation rate Vraax and the half-saturation constant Km were calculated to be 0.431 mmol/（***） and 0.169 mmol/L, respectively. Activity assay of catechol suggested that the strain ZW possessed a catechol- 1,2-dioxygenase and could decompose benzene-ring through ortho ring cleavage. Based on the identified intermediates by GC/MS, a new metabolic pathway was proposed, in which the final metabolites were some simpler organic and inorganic compounds. The present work demonstrated that the strain ZW would have a great application prospect for the remediation of α-pinene-contaminated environment.

由于我国人口迅速增长、耕地资源限制和粮食作物产区相对比较集中等各种因素的共同影响,在农业生产中作物长期连作已经形成了一个较为普遍的发展态势。随着连作年限的增加,作物生长受到不同程度的影响,因此连作障碍已成为制约绿色农业可持续发展的一个重要原因。许多作物在长期连作模式中都会发生连作障碍,这主要是由于植物的自毒作用、土壤中致病微生物的增殖、微生物区系失衡和土壤理化性质的劣变所引起,目前科研工作者们根据连作障碍重要因子研究出了多种绿色有效的生物防控方法,主要通过研制生物菌剂、有机肥、土壤强还原措施以及噬菌体疗法等来防控连作障碍,这些方法在防控连作障碍方面效果显著且绿色环保,符合我国绿色可持续发展理念。鉴于此,本综述针对目前连作障碍产生的主要因素,以及近年来提出的防控连作障碍的各种措施进行了阐述,并对该领域未来的研究方向进行了展望,为之后的连作障碍研究提供理论依据,以期克服作物连作障碍难题,促进现代农业的健康可持续发展。
