What fuel does the pond scum produce?
It turns out that algae produce oil that can be processed to make biodiesel. In some species, this oil represents more than half of the plantlike organism’s mass. Researchers are also trying to genetically alter algae to make them give off copious amounts of hydrogen to meet the needs of future fuel-cell-powered cars.
What is importance of pond scum?
Because pond scum and algae are living organisms, they are rich sources of nitrogen that break down quickly in the compost pile. Using pond scum as fertilizer also incorporates important nutrients, such as potassium and phosphorus, into the compost.
What kills pond scum?
A pound of rock salt can be added to 100 gallons of water to take out algae. This should be a last resort because the saltiness of the water will significantly increase and adversely affect plants and animals. Pond Academy: What Is Pond Scum (And How To Get Rid Of Floating Scum For Good!)
Can algae be used as a biofuel?
Algae are renewable resources for biofuels that can be grown on non‐arable lands, using saltwater or brackish water. A significant advantage of using algae for biofuels is that it need not displace farmland used for growing food sources.
What are two ways algae can be farmed for biofuel?
Currently, the suspension-based open ponds and enclosed photobioreactors are commonly used for algal biofuel production. In general, an open pond is simply a series of raceways outside, while a photobioreactor is a sophisticated reactor design which can be placed indoors in a greenhouse, or outdoors.
What are the two types of green algae?
Green algae, variable in size and shape, include single-celled (Chlamydomonas, desmids), colonial (Hydrodictyon, Volvox), filamentous (Spirogyra, Cladophora), and tubular (Actebularia, Caulerpa) forms. Sexual reproduction is common, with gametes that have two or four flagella.
How do I get rid of pond sludge?
Although pond sludge is dirty and smelly and too much of it can ruin a pond, you should not just dispose of it in a bin. Pond sludge should be recycled and used elsewhere in your garden either as a fertiliser or as an addition to your compost bin.
What are the characteristics of a green algae?
The typical green algal cell, which can be motile or nonmotile, has a central vacuole, pigments contained in plastids that vary in shape in different species, and a two-layered cellulose and pectin cell wall. Food is stored as starch in pyrenoids (proteinaceous cores within the plastids).
