Endophyte microorganisms have great biotechnological interest, with features applicable to different areas and are potentially useful in agriculture. In the current study, the most dominant and representative endophytic fungal species of seven halophytic plants prevalent in the southeastern Algeria, Touggourt, were screened for their ability to produce four extracellular enzymes namely: cellulase, amylase, laccase, and lipase. Zygophyllum album came first by hosting diverse endophytic species among all the tested plants with eight species followed by Tamarix boveana and Limoniastrum guyonianum (46.66%) as well as Phragmites communis with 40% and Haloxylon articulatum and Aeluropus littoralis with 33.33%. Unlike J. effusus, it was the less diverse plant where only three species (20%) were identified. In term of enzymatic activities of the selected fungi, the two species of Chaetomium presented cellulase, amylase and lipase activity. Unlike, Trichoderma harzianum involved in lipase, Ulocladium sp. in cellulase, Bipolaris sp. and Botryostimphylium sp. in Amylase. Unlike, the two species of Chaetomium involved in cellulase, amylase and lipase. On the other hand, no enzyme activity was recorded in the colonies of Fusarium sp.
