Abstract
Microcystis is the most common cyanobacteria found in Western Lake Erie harmful algae blooms (HABs). Its presence is concerning as it is capable of producing the cyanotoxin microcystin, which poses serious health threats to humans and aquatic life, as well as causing harm to local economies through a reduction in recreation. The Toledo drinking water crisis brought Lake Erie HABs to the national level in 2014, as 500,000 residents were without water for several days. Due to the severity of harm that the presence of toxic HABs have, this project aims to better understand Microcystis strains. However, in order to derive data and run controlled experiments, months are first spent growing colonies derived from Lake Erie field samples. After several rounds of culture isolation and microscopy, gene sequencing is done to confirm Microcystis was isolated. Once confirmed, cultures are maintained and added to our Western Lake Erie Culture Collection (WLECC). By continually growing and isolating new strains of Microcystis, a diverse library is created. Having a wide range of strains is essential for critically evaluating the species as a whole, which is the first step to gaining control over outbreaks that threaten access to clean and safe water.
