91356 - Harmful Algal Blooms and Biotoxins

Learning outcomes

At the end of the course, the student will have acquired competence on algal species that cause environmental problems (species producing toxins or other unwanted substances, invasive organisms or characterized by excessive proliferation) and on the dynamics with which negative effects on the environment and on 'man; learn the methods of monitoring and controlling unwanted species and any mitigation methods.

Course contents

Main problems related to the presence of harmful algae: blooms of microalgae (organisms involved, consequences for the environment and for humans, abiotic and biotic triggers); biointoxications and toxic algae (distribution, biology of the main groups, cell cycles, growth and nutrition strategies, chemical structure of toxins, mechanisms of action, relationship with other organisms, allelochemical interactions). Cyanobacteria and water treatments. Effects of climate change on the presence of algae. Methods of determination of toxins and problems related to their determination. Molecular methods for the classification and identification of algae and their use in monitoring activities.

Teaching methods

The course includes 16 hours of lectures and 12 hours of practise. The practical part is carried out in the didactic laboratories and foresee the preparation of algal cultures for the development of a toxicity test with standard method.

Assessment methods

Oral exam aimed at verifying the learning of the topics covered in class.

Teaching tools

Power point slides will be used for the lectures, and scientific articles of relevance on some topics will be used and commented.
