Algae

INTRODUCTION Spirulina platensis is a filametous blue-green algae (30–70 m helix diameter) (Sáncbez et al., 2003; Tomaselli, 1997). However, It have prokaryotic structure therefore they are a bacterium belong to cyanobacterium (Becker, 2006). Their cell wall contains peptidoglycan in its composition and structure, so it was classified as gram negative (Alessandro Novak, 2010). Spirulina can form population is fresh water and brackish lakes and some marine environments (Belov and Giles, 1997;

Are you sick of algae in your aquarium? Your saltwater aquarium lighting may be your problem… Algae is inevitable in any saltwater aquarium and will always be present as part of the natural ecosystem, however there are steps you can take as part of your ongoing saltwater aquarium maintenance schedule to decrease the rate and density of growth.There are several types of algae however the most common found in a saltwater aquarium is brown algae otherwise known as golden diatom algae. When I first

Negative impacts of Dinoflagellate algae: economic, ecologic, and human health hazards ABSTRACT Increasing pollution both atmospheric and oceanic are encouraging algal growth and increasing the frequency and geographic range of high density dinoflagellate blooms. Public health and economic impacts, as well as negative ecological effects of the aquatic environment are increasing the scientific research done on toxic dinoflagellate species. Contaminated bivalves are causing paralytic shellfish

Cause: Algae is growing in the pond because the nutrients produced by fish are absorbed by the algae, permitting it's growth. Solution: To remove the algae, there must be organisms that will absorb the nutrients produced by fish put into the pond. This is so there will be no nutrients left for the algae to feed off of, thus eventually eliminating the algae from the pond. The plants that could be put into the pond would be water lillies and lotuses. Hypothesis: If plants are put into the pond, then

Algae blooms have been an issue in the Chesapeake Bay, especially in the Baltimore Inner Harbor. Algae is a natural and critical part of the ecosystem, however in large doses it is harmful to the plants and organisms within the ecosystem. Algae blooms can block out sunlight and kill other plants in the water. Algae depends on various factors such as water, nutrients and carbon dioxide to grow. Eutrophication of the Inner Harbor has lead to algae blooms that have caused large fish kills in the past

News”. It was published on July 8 2015 regarding the algae growth in Jackfish Lake. The article title is “Yellowknife dump runoff may be causing Jackfish Lake algae blooms” and can be access here. Additional analysis and summaries can be read below. 2. Canada is a country that is well-known for its beautiful land and freshwaters. However, Jackfish Lake in Yellowknife was starting to display abnormal signs of algae growth. Currently, the algae displays a liver-like appearance and is spreading deeper

HAB, Harmful Algae Blooms can kill thousands of fish, even in small amounts. All aquatic life depends on food, most algae are harmless however, and some are harmful. HAB causes harm through fishes the humans who eat it get sick because HAB is toxic. This also affects the sea-life food web. The Gulf of Mexico’s Dead Zone is a large section of water with a big level of DO, Dissolved Oxygen and can’t support sea-life. Nitrogen and phosphorous nutrients wash into rivers, they put laden nutrients into

Introduction to Bio-oil production with Algae What is Bio-Oil? 1. Introduction to Bio-Oil and Algae strains Bio-Oil is an organic fuel that contains energy that is made from natural living organisms. They are produced from lipids which are merged with other ingredients which chemically produces Bio-Oil. Fossil fuels are generally easier to harness but it is produces a lot of carbon emission which is greatly detrimental to the health of the environment. Thus, the idea of Bio-fuel is introduced as

Modern Uses of Cultivated Algae Algae are a "group of plants" that dominate the aquatic environment (Raymount, 1984). Organisms that make up the algae include representatives from three kingdoms and seven divisions: cyanochloranta and prochorophyta (from Kingdom Monera), pyrrhophyta, chrysophyta, phaeophyta, and rhodophyta (from Kingdom Protista), and chlorophyta (from Kingdom Plantae). All seven divisions are called algae because of a lack of roots, stems, and leaves; and most algal cells are
