The Great Sebkha of Oran is a closed depression located in northwestern of Algeria. Despite the ranking of this sebkha among the wetlands of global importance by Ramsar Convention in 2002, no studies on the fungal community in this area have been carried out. In our study, samples were collected from two different regions. The first region is characterized by halophilic vegetation and cereal crops and the second by a total absence of vegetation. The isolated strains were identified morphologically then by molecular analysis. The biotechnological interest of the strains was evaluated by testing their ability to grow at different concentration of NaCl and to produce extracellular enzymes (i.e., lipase, amylase, protease, and cellulase) on solid medium. The results showed that the soil of sebkha is alkaline, with the exception of the soil of cereal crops that is neutral, and extremely saline. In this work, the species Gymnoascus halophilus, Trichoderma gamsii, the two phytopathogenic fungi, Fusarium brachygibbosum and Penicillium allii, and the teleomorphic form of P. longicatenatum observed for the first time in this species, were isolated for the first time in Algeria. The halotolerance test revealed that the majority of the isolated are halotolerant. Wallemia sp. and two strains of G. halophilus are the only obligate halophilic strains. All strains are capable to secrete at least one of the four tested enzymes. The most interesting species presenting the highest enzymatic index were Aspergillus sp. strain A4, Chaetomium sp. strain H1, P. vinaceum, G. halophilus, Wallemia sp. and Ustilago cynodontis.

奥兰大塞布哈是位于阿尔及利亚西北部的一个封闭洼地。尽管2002年拉姆萨尔公约将这片塞布卡列为全球重要湿地，但尚未对该地区的真菌群落进行研究。在我们的研究中，样本是从两个不同的地区收集的。第一个区域的特点是嗜盐植被和谷类作物，第二个区域则完全没有植被。然后通过分子分析对分离的菌株进行形态学鉴定。通过测试菌株在不同浓度的 NaCl 下生长以及在固体培养基上产生胞外酶（即脂肪酶、淀粉酶、蛋白酶和纤维素酶）的能力来评估菌株的生物技术兴趣。结果显示，塞卜卡的土壤呈碱性，但谷类作物的土壤除外，土壤呈中性，且盐分极高。在这项工作中，首次在阿尔及利亚分离出嗜盐裸子菌（Gymnoascus halophilus）、甘氏木霉（Trichoderma gamsii）、两种植物病原真菌短臂镰刀菌（Fusarium brachygibbosum）和青霉（ Penicillium allii），以及首次在该物种中观察到的长链青霉（ P. longicatenatum）的有性形态。耐盐性试验表明，大多数分离株具有耐盐性。瓦莱米亚属 嗜盐拟杆菌的两个菌株是唯一的专性嗜盐菌株。所有菌株都能够分泌四种测试酶中的至少一种。具有最高酶指数的最有趣的物种是曲霉属物种。菌株 A4，毛壳菌属 sp。菌株 H1、P. vinaceum、G. halophilus、Wallemia sp。和犬齿黑粉菌 (Ustilago cynodontis)。
