Maintenance Alert

Algal cultures are shipped in clear, two- to eight-ounce polystyrene jars. Immediately upon receipt, loosen caps and aerate cultures with clean pipet (included). Leave caps loosely in place to prevent contamination, yet permit air exchange. Cultures should receive diffuse light and be held in a temperature range of 18 to 22 °C. Maintain long-term cultures in clean culture dishes, flasks, or battery jars using an appropriate medium. For lighting use two 48-inch, 40-watt fluorescent bulbs (plant grow-light or wide-spectrum) at a height of 12 to 18 inches. Begin with a light cycle of 16 hours on 8 hours off and reduce to 12 hours on, 12 hours after 7 to 10 days. Subculture to fresh media every 6 to 8 weeks.Culture blue-greens under moderate to low light in Bristol's Modified Medium or Pringsheim's Soil Water.

Product Details

Nostoc. Freshwater and terrestrial. Unbranched filaments with heterocysts and akinetes. Tightly contorted filaments that occur in gelatinous aggregations that may reach baseball size. Cyanobacteria also known as the blue-green algae, are photosynthetic prokaryotic organisms utilizing chlorophyll a. Unlike other photosynthetic bacteria, the cyanobacteria evolve oxygen and may have been responsible for the early accumulation of oxygen in Earth's atmosphere. Species may be characterized by the formation of akinetes—thick-walled non-motile spores, and heterocysts—thick-walled translucent cells capable of fixing nitrogen.
