Which group of phototrophs contain a bluish pigment and chlorophyll a?
Cyanobacteria contain a bluish pigment called phycocyanin and chlorophyll a, allowing them to perform photosynthesis.
What color is anabaena?
Anabaena is blue-green in color, due to the presence of chlorophyll and phycocyanin pigments in its cells. These pigments help Anabaena carry out photosynthesis and give it its distinctive appearance.
What makes blue green bacteria green?
Blue-green bacteria (cyanobacteria) look greenish-blue because of the pigments they contain for photosynthesis. The main pigments are: Chlorophyll-a – 🔹 Gives the green color 🔹 Same pigment found in plants 🔹 Absorbs light for photosynthesis Phycocyanin – 🔹 A blue pigment 🔹 Unique to cyanobacteria and red algae 🔹 Helps absorb light in deeper or shaded water Why do they appear blue-green? The green from chlorophyll-a + the blue from phycocyanin = blue-green appearance. 💡 That’s why they’re called "blue-green algae" (even though they’re bacteria, not algae). Bonus: Some cyanobacteria also have phycoerythrin (a red pigment), which can shift their color more toward reddish or brownish, depending on the species and environment.
Biochemical tests for identification of cyanobacteria?
Common biochemical tests for identifying cyanobacteria include testing for the presence of chlorophyll a, phycocyanin, and phycoerythrin pigments. Additionally, assessing the ability to fix atmospheric nitrogen (nitrogen fixation) and conducting tests for the presence of gas vesicles are also used for identification purposes. Molecular techniques like PCR and sequencing can also be employed for more accurate identification.
Why are blue green algae called cyanobacteria?
Cyanobacteria are called BLUE GREEN algae because Red,Brown,Green and Blue pigments are present in them and that's why they are termed as Red,Blue,Green and Brown algae.TAHIR SAJJAD
What is the molar mass of c-phycocyanin?
The alpha chain is 18 kda and the beta is 21 kda. But usually Phycocyanin exists as trimer along with some linker peptides. The molecular weight of trimer is 121 kda
Where can you purchase phycocyanin - what is the price?
Phycocyanin is available in different grades/quality indexes Right from the food grade to analytical grade. It could be as cheap as 500 USD per KG to 100,000 USD per gram......
Does Phycocyanin helps in cancer treatment?
the usual presumption is that phycocyanin brings the cancer down (many supporting references) but one must be aware of the practical toxicities associated with its intake. Even physiologically acceptable and well reported doses (may be the published data was not scrutinized properly) have lead to toxic triggers in the body leading to fatalities like meningitis and lymphosarcomas in silent progress. Spirulina (the parent molecule of phycocyanin) is definitely a balanced wise option for phycocyanin intake where it is naturally designed "with in its acceptable limits". Extracted thing seem to be nasty during its metabolic action in pathologies as such and their respective role in trigger onset of such pathologies.
Which group of phototrophs contain a bluish pigment and chlorophyll a?
Cyanobacteria contain a bluish pigment called phycocyanin and chlorophyll a, allowing them to perform photosynthesis.
6 Name the pigment in cyanobacteria?
One of the pigments in Cyanobacteria is Zeaxanthin.
What are the active medicinal properties of spirulina?
Chlorophyll, phycocyanin, B vitamins, beta-carotene, gamma-linolenic acid, iron, calcium, magnesium, manganese, potassium, selenium, zinc, bioflavonoids, protein, evercetin.
What color is anabaena?
Anabaena is blue-green in color, due to the presence of chlorophyll and phycocyanin pigments in its cells. These pigments help Anabaena carry out photosynthesis and give it its distinctive appearance.
What colors can algae be?
Algae can be green, red, brown, or yellow depending on their pigments. Green algae, for example, contain chlorophyll for photosynthesis, while red algae contain phycoerythrin and phycocyanin pigments in addition to chlorophyll. Brown algae possess fucoxanthin pigments.
Are rodophyta contained chlorophyll?
yes they contained, they also cntained other accessory pigments like phycoerythrin, phycocyanin, carotene, and xanthphyll.
What is the molar mass of C?
The alpha chain is 18 kda and the beta is 21 kda. But usually Phycocyanin exists as trimer along with some linker peptides. The molecular weight of trimer is 121 kda
Which pigment has the highest molecular weight?
The pigment with the highest molecular weight is phycocyanin, which is a blue pigment found in certain types of algae and cyanobacteria. It is a protein pigment complex with a molecular weight ranging from 30,000 to 34,000 Daltons.
