摘要

当前工作的目标是评估从埃及 El-max 海湾污染区分离出来的海洋真菌产生的生物表面活性剂 (BS)，用于对受石油污染的海水进行生物修复。为此，本研究采用了油位移（OD）、乳化指数（E24）、溶血试验和表面张力（ST）四项生物表面活性剂评估试验来筛选所选的海洋真菌分离物。通过测定 1.5 厘米油位移、E24 57%、溶血活性和最高表面张力 37.1mN/ m，发现 Plectosphaerella cucumerina 菌株 HBKB 被认为是生产高活性生物表面活性剂的最有效分离菌株。为了评估影响最小盐培养基（MSM）中生物表面活性剂产生的因素，Plackett-Burman

Assessment of Docosene Surfactant Mediated Crude Oil Remediation by Marine Plectosphaerella cucumerina Strain HBKB

The goal of the current work was to assess biosurfactant (BS) produced by marine fungal isolated from the contaminated site of El-max Bay, Egypt, for bioremediation of oil contaminated sea water. In this regard, the four biosurfactants assessment tests oil displacement (OD), emulsification index (E24), hemolysis tests, and surface tension (ST) were used to screen selected marine fungal isolates. By measuring 1.5cm oil displacement, E24 57%, hemolytic activity, and the highest surface tension 37.1mN/ m, Plectosphaerella cucumerina strain HBKB was considered as the most potent isolate for producing a highly active biosurfactant. To assess the factors influencing biosurfactant production from minimal salt medium (MSM), Plackett-Burman

期刊介绍： The main focus of Egyptian Journal of Aquatic Biology and Fisheries is to publish peer-reviewed, original papers relating to the biology and ecology of fresh, brackish and marine wetlands. Papers on applied research in both fisheries and aquaculture are so encouraging. Preference will be given to studies that address timely and current topics such as impact of climate change and green economy. The aim of Egyptian Journal of Aquatic Biology and Fisheries is to provide a wide scope for the aquatic biologist and limnologist to address and evaluate fisheries issues related to processes and functioning at different levels (individuals, communities and ecosystems).
