Oscillatoria Rubescens

Genus Oscillatoria Vaucher is the ubiquitous Cyanoprokaryote, growing in almost all habitats in fresh-water ecosystem like bils, dighis, lakes, ponds, wetlands, and marine water system like - salt marshes and pans, estuaries, brackish waters and ocean. It also occurs on inter-tidal rocks, snow and even in cold lakes underneath 5 m of ice pack as well as in thermal springs. During systematic investigations recorded altogether 25 species, 4 variety and 2 forms from Maldah District viz. Oscillatoria acuta Bürhl and Biswas, Oscillatoria agardhii Gomont, Oscillatoria amoena (Kütz.) Gomont, Oscillatoria amphibia C.Agardh ex Gomont, Oscillatoria amphigranulata Goor, Oscillatoria angusta Koppe, Oscillatoria chalybea G.Mertens ex Gomont, Oscillatoria formosa Bory ex Gomont, Oscillatoria formosa f. loktakensis Brühl and Biswas, Oscillatoria geitleriana Elenkin, Oscillatoria geminata Menegh. ex.

However, Oscillatoria subbrevis Schmidle, Oscillatoria tenuis C.Agardh ex Gomont are the most common species followed by Oscillatoria amphigranulata Goor, Oscillatoria acuta Bürhl and Biswas, Oscillatoria amphibia C.Agardh ex Gomont, Oscillatoria amphigranulata Goor in water bodies of Malda District. Oscillatoria redekei Goor is reported new from India.

Oscillatoria Rubescens

On a balmy day in June 1955, George Anderson took his sailboat out on Lake Washington, the long stretch of fresh water that separates Seattle from its eastern suburbs. Anderson had recently finished his doctoral research on phytoplankton, and knew the lake well. The water that day looked odd; he noticed a strange brown tinge. So he collected a sample in an empty beer bottle and brought it back to the University of Washington lab where he worked with his mentor, W.T. Edmondson, the ranking authority on the lake. Under the microscope, Anderson and Edmondson found a life form they’d never seen before. It grew in long, narrow chains, striated with lines that separated one cell from the next. They thought this might be a species infamous among limnologists, the cyanobacterium Oscillatoria rubescens. (Cyanobacteria, popularly known as blue-green algae, are in fact distinct from and far more ancient than algae. They appeared more than 3 billion years ago, when the planet was inhabited only by microbes, and were the first organisms to evolve photosynthesis. Their proliferation and release of great volumes of oxygen profoundly changed the chemical makeup of Earth’s atmosphere, making the evolution of complex life possible.) The researchers needed to be sure, so they sent a sample off to an expert, who confirmed their suspicions. O. rubescens signaled deteriorating conditions in Lake Washington. To Edmondson, it also meant an unprecedented opportunity to track the impacts of nutrient overload. O. rubescens had been the harbinger of drastic change in a number of western European lakes. The best-known case was that of Lake Zurich in Switzerland. Fed by Alpine glaciers, Lake Zurich was, until the late 1800s, an expanse of blue known for its abundant populations of whitefish and lake trout, which thrive in deep water. The lake is made up of two basins separated by a narrow passage. In the late nineteenth century towns at the edge of the lower basin, the Untersee, abandoned privies for flush toilets, and began to release their raw sewage into the lake.

Oscillatoria Rubescens

Species of green algae seldom grew as well in two-species cultures with other green algae, or with blue-green algae, as when cultured alone. Several species of algae apparently excreted one or more substances into the medium which inhibited the growth of the second species. Inhibition of growth of green algae was particularly great in two-species cultures with the blue-green algae,Oscillatoria rubescensDecandolle,Anabaena flos-aquae(Lyngbye) Breb.,Microcystis aeruginosaKutz., andCoccochloris peniocystis(Kutz.) Dr. and Daily. Green algae also failed to grow at normal rates in media prepared from filtrates of water from ponds which contained blooms of blue-green algae. Inhibitory substances are apparently an important factor in the development and persistence of relatively unialgal blooms of various species.
