Lakes of Africa: Microbial Diversity and Sustainability examines microbial ecosystems in African lakes, including the history and formation of African lakes. The book describes how environmental stressors—including seasonal variations, climate change, and anthropogenic activities—affect microbial ecosystem dynamics in African lakes and the microbial responses to these stressors. The book explores and evaluates extremophiles in African lakes, including industrial biotechnology applications. The book highlights challenges facing microbial ecology in African lakes, as well as the design of models for solving these problems and predicting the future of lake microbial ecosystem sustainability.
