Oilgae Highlights
Green Algae make up the division Chlorophyta, which includes
about 7,500 species of eukayotic, unicellular organisms. Some of the unifying
characteristics of this division include similar photosynthetic pigments that
make up the chloroplast, which include Chlorophylls a and b, and a -, b -,
and g -carotenes; and some xanthophylls and primary carotenoids. Almost all
green algae store their carbohydrates in the form of starch. For the most
part, their cell walls are composed of polysaccharides, including cellulose.
The most obvious organelle of green algae is their chloroplast, which is
responsible for giving them their green color.
The "green algae" is a paraphyletic group
because it excludes the Plantae. Like the plants, the green algae contain two
forms of chlorophyll, which they use to capture light energy to fuel the
manufacture of sugars, but unlike plants they are primarily aquatic. Because
they are aquatic and manufacture their own food, these organisms are called
"algae," along with certain members of the Chromista, the Rhodophyta,
and photosynthetic bacteria, even though they do not share a close
relationship with any of these groups.
From Wikipedia: “The green algae (singular: green alga)
are the large group of algae from which the embryophytes (higher plants)
emerged. As such, they form a paraphyletic group, although the group
including both green algae and embryophytes is monophyletic (and often just
known as kingdom Plantae). The green algae include unicellular and colonial
flagellates, usually but not always with two flagella per cell, as well as
various colonial, coccoid, and filamentous forms. In the Charales, the
closest relatives of higher plants, full differentiation of tissues occurs.
There are about 6000 species of green algae. Many species live most of their
lives as single-cells, other species form colonies or long filaments.”
Most green algae are present in fresh water, but there are
diverse green algae in tropical marine habitats. Like land plants, the greens
store starch (amylose or amylopectin) and have chlorophyll a and b as well as
secondary pigments : carotenes, lutein, zeaxanthin. (Some Chlorophyta also
have siphonoxanthin.) The chloroplast endoplasmic reticulum is absent in
green algae, and t heir cell walls are often composed of cellulose, hydroxproline,
glycosides, xylans, mannans or sometimes calcium carbonate.
Green algae may be unicellular, multicellular, colonial or
coenocytic (composed of one large cell without cross-walls; the cell may be uninucleate
or multinucleate). They have membrane-bound chloroplasts and nuclei. Most
species are aquatic and are found commonly in freshwater and marine habitats;
some are terrestrial, growing on soil, trees, or rocks. Some are symbiotic
with fungi giving lichens. Others are symbiotic with animals.

(green algae): Over 5,000 species of green algae are known, mostly unicells
or simple filaments from fresh water, but there are diverse green algae
in tropical marine habitats. Like land plants, the greens store starch (amylose
or amylopectin) and have chlorophyll a and b as well as secondary pigments
: carotenes, lutein, zeaxanthin. (Some Chlorophyta also have siphonoxanthin.)

- Chlorophyta
- The Green Algae: Globally distributed, in freshwater, marine, and
terrestrial environments Land plants (Kingdom Plantae, or the embryophyta)
are specialized green algae adapted to life on land An ancient group
according to the fossil record, green algae are extremely diverse. Often
dominant algae in freshwater environment.
- Characteristic
Chlorophyta: Green Algae: Green colour from Chlorophyll a and b in
the same proportions as the 'higher' plants; ß-carotene; and
various characteristic xanthophylls. Food reserves starch, some fats or
oils like higher plants. Thought to be the origin of the higher green
plants but there is currently some doubt on this point.

seaweeds that might be encountered in California.
Blue-green & Yellow-green
algae
- Blue-green
Algae: Blue-green algae are types of bacteria known as Cyanobacteria,
which occur naturally in habitats such as rivers, lakes, damp soil, tree
trunks.
- Introduction
to the Cyanobacteria: Cyanobacteria are aquatic and photosynthetic,
that is, they live in the water, and can manufacture their own food.
Because they are bacteria, they are quite small and usually unicellular,
though they often grow in colonies large enough to see.
- Bluegreen
Initiative – Overview: Cyanobacteria produce a number of nuisance
compounds, including those that are toxic or cause severe taste-and-odor
problems in drinking water supplies. Cyanobacterial toxins can
make drinking water and recreational use of water unsafe.
- Blue-Green
Algae (Cyanobacteria) and their Toxins: Cyanobacteria is the scientific
name for blue-green algae, or "pond scum." The first
recognized species were blue-green in colour, which is how the algae got
their name. Species identified since range in colour from olive-green to
red.
- Why be
Concerned about Blue-Green Algae?: Blue-green algae, (cyanobacteria)
are a common and natural component of the microscopic plants (plankton)
in Lake Champlain. Some kinds of blue-green algae produce natural toxins
or poisons. When these algae die and break down, toxins can be released
into the water.

Green Algae Benefits: Blue green algae have been used for weight
loss and as a nutritional supplement. It has also been used for boosting
the immune system and for controlling cholesterol levels.

Benefits of Spirulia: Spirulina's scientific name is arthrospira platensis.
This edible algae has a long history of safe human consumption and over
30 years of safety testing. Special farms where spirulina is cultivated
under controlled conditions do not allow the growth of other contaminant
blue-green algae, as in lakes and waterways.

10 Health Benefits Of Blue Green Algae: Blue green algae also
contain about 60 to 70% of vegetable protein, and provide all the essential
amino acids. All these benefits without the risk of consuming meat,
which is high in cholesterol and is difficult to digest.
- Uses
And Benefits Of Blue Green Algae: A wild-crafted, organic, all
natural superfood, blue green algae is one of best foods in the world.

ways to stay in healthy.
- Permanently
Remove Green Pool Algae: Green algae is a common swimming pool
problem, which may appear as a greenish .... Permanently Remove Green
Pool Algae.
- Info About
Pool Algae: The first noticeable problem is that no one seems to
want to go swimming. The second problem is that it requires work and
effort and money to rid the water completely of algae. It is therefore
best to use preventative chemicals and techniques.
- Algae
and Algaecides: A proper chemical program of regular pool
maintenance prevents algae from growing. This means keeping the proper
pH and recommended free chlorine residual for your pool. The best
algaecide (algae killer) and algaestat (algae inhibitor) is a properly
maintained sanitizer level of 1-3 ppM Chlorine or 2-5 ppM Bromine for a
pool and 3-5 ppM Chlorine or 3-6 ppM Bromine in a spa.
- Types
of Algae in Swimming Pool: Algae is a common problem in swimming
pools. What is it; what are the different types & how is it
successfully prevented and treated ar explained in this site.
- Pool water
problem – algae: Algae is the most common pool water problem only
because it is the most visibly obvious one. Algae in itself is not
dangerous - in fact it is the main ingredient in many health supplements
and tablets. Algae brings danger in that it converts sunlight into food,
releasing wastes that become the feeding grounds for unwanted and
harmful bacteria and other micro-organisms.
- Fatty
acid amides from freshwater green alga Rhizoclonium hieroglyphicum:
Freshwater green algae Rhizoclonium hieroglyphicum growing in the Ural Mountains
were examined for their fatty acid amides using capillary gas
chromatography–mass spectrometry (GC–MS). Eight fatty acid amides were
identified by GC–MS. (Z)-9-octadecenamide was found to be the major
component (2.26%).
- Introduction
to the Chlorophyceae - fresh-water green algae: The Chlorophyceae are
a large and important group of freshwater green algae. They include some
of the most common species, as well as many members that are important
both ecologically and scientifically.

- Introduction
to the Xanthophyta Yellow-green Algae: The Xanthophyta include more
than 600 species. Members of this group are photosynthetic organisms
which live primarily in freshwater, though some are found in marine
waters, in damp soil, or on tree trunks. They generally are not abundant
when they are found at all, and many species have only been found once.
Despite this, they are the dominant producers in some salt marshes, and
some, like Tribonema, are cosmopolitan in their distribution.
- Yellow
Green Algae: Yellow Green Algae are eucaryotic cells with two apical
flagella (anterior and posterior). They contain chlorophyll.
- Yellow-green
Algae: The yellow-green or tribophyte algae are named for the genus Tribonema.
The group includes about 100 genera, many of which are rare.
- What is
this Wild Freshwater Blue Green Algae?: Aphanizomenon flos-aquae
grows in wild abundance in Klamath Lake in Southern Oregon. The shallow
lake is fed by pure waters called the "Rivers of Light", and
the algae that grows in the lake is nourished by 35 feet of volcanic
mineral-rich sediment on the bottom and sunlight almost every day of the
growing season.
- How
Spirulina is Different from Wild Blue Green Algae: Many people have
asked about the differences between spirulina and wild blue-green algae
harvested from lakes. Spirulina is one particular kind of blue-green
algae with a centuries long history of safe human consumption. It is
well known to be safe and nutritious. Hundreds of published scientific
studies over the past thirty years have documented no toxicity.
- Wild
Blue-green Algae : This guide provides information on the blue-green
algae of Upper Klamath Lake, in Oregon, in the USA. This algae is rich
in nutrients, and can, if taken as a dietary supplement, improve health
and vitality by stimulating the immune system and boosting brain
activity.
