Isolation, identification, marine algaeAbstract
The present work was mainly intended to study the marine algae from Al-Hariga port. The study was carried out from spring to autumn (2020). Sea water samples were collected from the coast of the city of Al-Hariga port which were microalgae, and macro-algae (seaweeds) and identified. A total of 47 algal species (36 genera) that were recorded in the study area are able to grow on crude oil. Seven species of them (14.89%) were belonging to Cyanobacteria (4 families), eleven species (23.40%) belonged to Chlorophyta (9 families), twenty-four species (51.64%) belonged to Bacillariophyta (11 families), three species (6.38%) belonged to Phaeophyta (3families) and two species (2.26%) belonged to Rhodophyta (1family). The obtained results showed that the most common Nitzschia was found with four species and Licmophora was found with three species. However, diatoms were the most dominant species in this area during three seasons. The study area had three brown algal species, The absence of this species in the port is due to oil pollutants, A total of two species of red marine algae (2.26%) was recorded in the current Al-Hariga port area with a special reference to the family of the Corallinaceae. Although some good indicators of algae were recorded, one could conclude that the study area is relatively poor in marine algae and polluted.
