Large scale outdoor algal cultivation in open pond system

Abstract

Large-scale algal cultivation refers to the process of growing algae in large quantities for various purposes, such as biofuel production, food, and cosmetics. Algae are attractive as a biofuel source due to their high growth rates, ability to grow in a variety of environments, and ability to capture carbon dioxide. In large-scale algal cultivation, several factors must be taken into consideration, such as the choice of species, the type of cultivation system, and the cultivation conditions. Algae can be grown in open ponds, photo bioreactors, or hybrid systems, and each system has its advantages and disadvantages. Crop protection is also a crucial aspect of large-scale algal cultivation, as algae are susceptible to various diseases and pests that can reduce yield and quality. Common crop protection measures for algal cultivation include the use of biocontrol agents, such as predatory microorganisms or enzymes, and physical barriers, such as netting or screens. In addition to crop protection, other challenges in large-scale algal cultivation include the high cost of production, the need for large amounts of water and nutrients, and the development of efficient harvesting and processing techniques. Overall, large-scale algal cultivation has the potential to be a sustainable and renewable source of energy and other products.
