Microcystis Wesenbergii
microcystis wesenbergii
Microcystis wesenbergii is a fascinating, colonial single-celled cyanobacterium commonly found in freshwater environments globally. Known for forming floating colonies, this photosynthetic bacterium plays a complex role in aquatic ecosystems. While it contributes to primary productivity by harvesting sunlight, it is also famous for its involvement in harmful algal blooms under nutrient-rich conditions. Unlike some of its notorious relatives, Microcystis wesenbergii is often considered less toxic or non-toxic, though it frequently co-occurs with toxin-producing species. Encased in a distinct, well-defined gelatinous sheath, these microscopic organisms cluster together, using buoyancy-regulating gas vesicles to move up and down the water column to optimize light absorption.
生息地: Found floating in eutrophic freshwater lakes, reservoirs, ponds, and slow-moving rivers worldwide.
外見
Microcystis wesenbergii forms spherical, lobed, or irregularly shaped colonies that range from pale green to blue-green in color. Individual cells are spherical, measuring about 4 to 7 micrometers in diameter, and are packed within a highly visible, refractile, and structured mucilaginous envelope. This outer gelatinous sheath has a sharp, distinct boundary that clearly distinguishes it from other Microcystis species under a light microscope. Macroscopically, dense accumulations look like green pea-soup or spilled paint on the water surface.

おもしろい事実
They use specialized gas vesicles to climb up to the surface during the day to photosynthesize, and sink at night to absorb nutrients from cooler, deeper waters.
Under a microscope, the defining feature of Microcystis wesenbergii is its remarkably crisp, glass-like outer gelatinous border, which looks like a clear halo.
While some Microcystis species produce deadly microcystin toxins, M. wesenbergii is generally considered non-toxic, though it often lives alongside highly toxic cousins.
特殊能力
能力
Buoyancy Control
Uses gas-filled vesicles within its cells to adjust its vertical position in the water column, rising to harvest sunlight or sinking to access deeper nutrients.
能力
Gelatinous Shield
Produces a thick, resilient outer mucilage envelope that protects cells from mechanical damage, desiccation, and chemical fluctuations in the environment.
能力
Efficient Light Harvesting
Utilizes phycobiliproteins alongside chlorophyll to capture light wavelengths that other photosynthetic organisms cannot use, allowing it to thrive in turbid waters.
食性と食事
As a photosynthetic cyanobacterium, it generates its own energy from sunlight, water, and carbon dioxide, while absorbing dissolved nutrients like phosphorus and nitrogen directly from the surrounding water.
