What is Applied Phycology List of Algae Which are being Used Commercially Role of Algae in Industry

Applied phycology manages the functional use of green growth. It incorporates an assorted cluster of fields including algal culture and ocean growth cultivating, the use of green growth to make business items, for example, carotenoids, hydrocolloids, and drugs, green growth as soil conditioners improve the actual characteristics of the dirt, in biofertilizers, the utilization of green growth in the treatment of wastewater, green growth as ecological pointers, in diminishing CO2 emissions ,in sustainable power creation and natural bioremediation. 

The business creation of microalgae and ocean growth and the items got from them is a tremendous and grounded industry. Novel algal species alongside new and improved yield of items and with successful bioremediation property are by and large ceaselessly developed. Selection of algal genera and species and their hereditary control prompts a high creation of wanted synthetic substances or movement, henceforth making another biotechnological field. 

This part is planned to give a prologue to the significance and employments of green growth. Subsequent to learning grouping, life cycles and other tiny subtleties in the prior sections it is 


Spirulina(Arthrospiraplatensis): Spirulinais a filamentous alga and is created in Japan, Taiwan, China, India, Thailand, USA for the wellbeing food market. It is likewise utilized as a wellspring of phycocyanin and basic unsaturated fats.Other Chrysophytes of interest are Anabaena, Nostoc, Oscillatoria. 


Dunaliella salina: It is the star among the economically significant green growth and is being filled monetarily in Israel, India, Australia and China. It has a high substance of β-carotene which is the forerunner of Vitamin A. 

Botryococcus braunii:This is the oil delivering green alga. It creates huge amount of long-chain hydrocarbons. 

Tetraselmis spp.: The family is broadly utilized in hydroponics offices as feed for adolescent molluscs, shrimp hatchlings and rotifers. Furthermore, high lipid-containing strains can possibly be utilized in biofuel creation. 

Some different Chlorophytes of interest are Scenedesmus, Nannochloropsis, Chlamydomonas, Euglena and Asteromonas. 


Macrocystis pyrifera: It is regularly known as goliath kelp. Monster kelp is a wellspring of alginate and minerals, for example, iodine and potassium. 

Laminaria: It is a wellspring of iodine and mannitol. Laminaria is of food esteem and forestalls fat retention consequently advances weight reduction. 

Other Phaeophytes of interest are Sargassum, Undaria, Turbinaria, Ascophyllumnodosum and so forth 


Porphyridium: It is a wellspring of sulphated polysaccharides, basic unsaturated fats (arachidonic corrosive) and phycoerythrin. Other Rhodophytes of interest are Porphyra, Chondruscrispus and so on 


Isochrysis galbana: It is a significant hydroponics feed. Some other Chrysophytes of interest are Nitzschia, Cylindrotheca, Amphora and Chaetoceros. 

Green Growth in Biotechnology and Industry

1. Polysaccharides: 

Larger part of the common polysaccharides used in industry come from green growth and organisms. The utilization of algal polysaccharides is more normal in the food business and drug industry due to the interesting idea of algal polysaccharides. The fundamental employments of these polysaccharides in food industry are as gelling specialists, thickeners, stabilizers, and emulsifiers. 

They are likewise utilized in makeup and in paper enterprises. Agar and carrageenan are the two significant polysaccharides extricated from red green growth. Alginates or alginic corrosive are removed from earthy colored green growth. It has been assessed that ocean growth separates add to a yearly turnover of a few hundred million dollars. 

(I) Agar-agar: Agar is a dried or gel like non-nitrogenous substance separated from red green growth. The principal business agar was delivered in 1670 in Japan, which is as yet perhaps the biggest provider agar on the planet. The start of agar industry in India is around 1965, and today in excess of six plants are in activity of which Ahmedabad alone creates around 100 kg of agar for every day. The current assembling limit of Indian businesses is about in excess of 70 tons for each year. 

Arrangement: It is a polysaccharide which gathers in the cell mass of red green growth alongside cellulose. Agar is a combination of agarose, the straight polysaccharide and agaropectin, a heterogenous combination of little particles. Agar contains galactans, α-galactose and β-galactose deposits with a little measure of sulfate esterification. 

Sources: The primary wellsprings of agar are thalli of Gelidium, Gracilaria and Gigartina. Agar is a coagulated, clear, nitrogen free concentrate from the previously mentioned genera of red green growth. The concentrate is a gel containing galactose and a sulfate. Its dissolving point is around 90-100ºF. At lower temperatures it changes into a strong. 

Employments of Agar

(i) Agar is utilized as a gelling and thickening specialist in food industry in the readiness of puddings, jams, jams and so on, as a stabilizer for mayonnaise and as emulsifying specialist in frozen yogurts. 

(ii) In the readiness of culture media in research centers as a hardening specialist for refined microorganisms, for example, microbes, green growth, parasites and in tissue culture procedures. 

(iii) It is utilized as a purgative to treat persistent obstruction. 

(iv) As a stabilizer in beautifiers for the readiness of balms, creams and emulsions. 

(ii) Carrageenan: Carrageenan are straight sulphated polysaccharides present in the cell dividers of red green growth. 

The main wellspring of Carrageenan is a red alga Chondral crisp's (Irish greenery) and less significantly Gigatrend. Carrageenan's are regularly utilized in food industry for their thickening, gelling and balancing out properties. Mostly three assortments of carrageenan have been perceived based on their level of sulfating. These are: κ-(Kappa) carrageenan (described by one sulfate for every disaccharide), ί-(particle) carrageenan (two sulfates for each disaccharide) and λ-(lambda) carrageenan (three sulfates for every disaccharide).
