Microalgae are microscopic photosynthetic organisms frequently found in fresh and marine water ecosystems. Various microalgal species have been considered a reservoir of diverse health-value products, including vitamins, proteins, lipids, and polysaccharides, and are broadly utilized as food and for the treatment of human ailments such as cancer, cardiovascular diseases, allergies, and immunodeficiency. Microalgae-derived carotenoids are the type of accessory pigment that possess light-absorbing potential and play a significant role in metabolic functions. To date, nearly a thousand carotenoids have been reported, but a very less number of microalgae have been used for the commercial production of carotenoids. This review article briefly discussed the carotenoids of microalgal origin and their therapeutic application. In addition, we have briefly compiled the optimization of culture parameters used to enhance microalgal carotenoid production. In addition, the latest biotechnological approaches used to improve the yields of carotenoid has also been discussed.

This paper presents design and performance analysis of Permanent magnet Brushless DC motor of 1.5 KW used in solar vehicle and hybrid electric vehicle. Finite element method (FEM) is used for determining the performance characteristics of motor. Permanent magnet brushless DC motor, design and its dynamic performance analysis is done on ANSYS/RM Expert and then its electromagnetic studies has done on ANSYS/Maxwell 3D.In last motor is analyze by varying the lead angle in control circuit.
