Now Easily Getting Your Favorite Marine Algae At An Affordable Price

A wide range of solid and liquid separation techniques are available for harvesting microalgae. The techniques of harvesting microalgae include coagulation and flocculation, flotation, centrifugation, and filtration or a combination of various techniques. Despite the importance of harvesting microalgae also to the economics and energy balance, there is no universal harvesting technique for microalgae. Therefore, this review focuses on the main harvesting processes applied to, presenting the main advantages and disadvantages of each method, to allow the selection of an appropriate procedure of Biotechnology company in India to effectively separate microalgae biomass from the culture medium.

Marine plants come in two forms. Some marine algae are so small usually they can only be seen under a microscope. Others are very large called microalgae or seaweeds, such as Macro cystic, a species of kelp belonging to the Algae group, which may reach 60 meters in length. Because of its salt content and also salt water is more economical than fresh water for growing major algae. The main nutrients needed for complete algae growth is already present in seawater. Macro-algae is cultivated at sea and harvesting algae mainly by simply tying them to anchored floating lines. Seaweeds do not require any type of soil and are already provided with all the sea water they need, a major advantage over land production of biofuels since seawater is the most limiting factor for mainly agricultural expansion also and especially with climate change. Many countries have limited land for farming or growing oil crops, or for those matter Cultivating marine algae, but have much larger ocean areas. So a natural question for macro algae that arises is how can algae be cultivated in ocean environments for biodiesel. It will be always extremely difficult in open also uncontrolled environments to keep lower, undesirable strains of complete algae from taking over high oil algae, which are not particularly competitive in such open natural environments.

One of the main costs associated with microalgae production is related to the harvesting process, as it usually accounts for about 20–30% of the total cost. To reduce the associated costs, it is common to harvest microalgae in a two-step separation thickening procedures, in which microalgae slurry is concentrated to about 2–7% of total suspended solids and dewatering procedures, which result in the concentration of microalgae slurry to 15–25% of total suspended solids. Selection of the adequate harvesting microalgae methods depends on the characteristics of the target microorganism biotechnology and also on the type and value of the end product.
