What is the size of oscillatoria?
Lyngbya (including species moved to Limnoraphis) and Oscillatoria have short, wide, coin-like cells (2-8 μm in length; up to 25 μm in width; for comparison, a strand of spider silk is about 5 μm wide). Lyngbya (and Limnoraphis ) filaments are surrounded by a firm mucilage sheath.
How do I know if I have oscillatoria?
Oscillatoria is a genus of filamentous cyanobacteria which is named for the oscillation in its movement. Filaments in the colonies can slide back and forth against each other until the whole mass is reoriented to its light source. It is commonly found in watering-troughs waters, and is mainly blue-green or brown-green.
What is the scientific name of oscillatoria?
Oscillatoria
Oscillatoria/Scientific names
Does oscillatoria have specialized cells?
As prokaryotes, they lack the definite nucleus and membrane-bound organelles (specialized cellular parts) of eukaryotic cells. They reproduce principally by transverse binary fission, although transfer of DNA between bacteria is widespread and forms the basis of recombinant DNA technology.
Does Merismopedia have specialized cells?
Merismopedia. Figure 5. Filamentous blue-green algae lacking specialized cells: a.
Is Oscillatoria harmful?
For example, Oscillatoria is able to fix nitrogen to supplement its growth in nitrogen-depleted environments. But the most concerning difference between an Oscillatoria bloom and one dominated by Microcystis is that the latter is a notorious toxin producer, and the toxins can be harmful to animals, including humans.
Does Merismopedia have Heterocysts?
7A) Merismopedia comprises flattened, free-living, platelike (rectangular), more or less rectangular colonies that have one layer of cells, arranged loosely or densely in perpendicular rows and enveloped by fine, colorless, usually indistinct, and marginally diffuse mucilage.
What makes a Planktothrix different from other Oscillatoriales?
P. agardhii is regarded as a type species of the genus. Like all the Oscillatoriales, Planktothrix species have no heterocyst and no akinetes, but are unique because they are planktonic, solitary trichome and have gas vacuoles.
What kind of blooms does Planktothrix rubescens produce?
Planktothrix rubescens culture. Note the reddish brown color which gave this strain’s algal blooms the name “Burgundy-blood phenomenon” Both P. agardhii and P. rubescens have the ability to form massive blooms in freshwater lakes and reservoirs.
Which is the type species of Planktothrix algae?
Planktothrix is a genus of filamentous cyanobacteria (often called blue-green algae). P. agardhii is regarded as a type species of the genus. Like all the Oscillatoriales, Planktothrix species have no heterocyst and no akinetes, but are unique because they are planktonic, solitary trichome and have gas vacuoles.
What kind of compound is found in Oscillatoria?
A sample of Oscillatoria sp., collected in Gokashowan Bay, Japan, was cultured and found to produce the polyketide compound 74 and given the trivial name oscillariolide. 168 Oscillariolide consists of a 14-member macrolactone with an attached tetrahydrofuran ring and a polyketide chain containing a terminal bromoalkene.
