Skrócony opis: (tylko po angielsku)

The course "Biology of phototrophic bacteria" covers issues related to the diversity, evolution, structure, occurrence, and role of phototrophic bacteria in the natural environment and their impact on human and animal health. Representatives of various taxonomic and ecological groups of phototrophic bacteria as well as phototrophic bacteria forming toxic and non-toxic blooms will be discussed.

Lecture:

As part of it, the types of autotrophy and phototrophy will be discussed, followed by the phylogeny, taxonomy and diversity of phototrophic bacteria. The biology of anoxygenic and oxygenic phototrophic bacteria (cyanobacteria), their role in shaping the environment (including oxygen conditions on Earth and Great Oxidation Event) and methods of their study will be presented. The occurrence of anoxygenic phototrophic bacteria and cyanobacteria in various environments, including extreme conditions (water, soil, hot springs, microbial mats, biological soil crusts in hot and cold deserts, symbiotic systems, etc.) will be discussed. Ecophysiological properties, occurrence, and diversity of picocyanobacteria - the smallest and the most numerous oxygenic photoautotrophs will be presented.

The genetic basis of cyanobacterial toxicity and the evolution of toxicity genes will be discussed followed by types of cyanobacterial toxins and their impact on other organisms, including human. Students will learn about the causes and mechanisms of cyanobacterial bloom formation and methods of cyanobacterial toxicity testing and cyanobacterial bloom mitigation. The influence of climate on bacterial phototrophic communities will be discussed. Application of cyanobacteria and anoxygenic phototrophs in biotechnology and medicine presented.

Practical:

Classes will concern the diversity of phototrophic bacteria and their habitats. Students will learn the sampling methods of water, soil and from transition environments, methods of storage, isolation and cultivation of oxygenic and anoxygenic phototrophic bacteria on liquid and solid media. Students will learn how to identify phototrophic bacteria using light, straight and inverted microscopes, biometrics and fluorescence. They will get acquainted with the methods of molecular identification of various taxonomic groups and with the methods of studying their relationships. Based on organisms isolated from environment and strains from culture collections, they will learn how to identify toxic and non-toxic representatives of cyanobacteria. Students will also learn about the methods of determining the number and biomass of phototrophic bacteria based on photosynthetic pigments: chlorophyll a, phycocyanin and bacteriochlorophyll, and methods of analyzing cyanobacterial toxins.
