“…Microalgae can be virtually found everywhere close the surface of the planet (Chen et al, 2019). From the hot equator to the perennially frozen polar regions, algae can be found in seas, rivers, lakes, wet surfaces, rocks, even deserts, and snow.…”

The alga Chlamydomonas nivalis thrives in polar snow fields and on high-altitude mountain tops, and contributes significantly on primary production in the polar regions, however, the mechanisms underlying this adaptation to low temperatures are unknown. Here, we compared the growth, photosynthetic activity, membrane lipid peroxidation, and antioxidant activity of C. nivalis with those of the model alga C. reinhardtii, under grow temperature and low temperatures. C. nivalis maintained its photosynthetic activity in these conditions by reducing the light-harvesting ability of photosystem II and enhancing the cyclic electron transfer around photosystem I, both of which limited damage to the photosystem from excess light energy and resulted in ATP production, supporting cellular growth and other physiological processes. Furthermore, the increased cyclic electron transfer rate, carotenoid content, and antioxidant enzyme activities jointly regulated the reactive oxygen species levels in C. nivalis, enabling recovery from excess excitation energy and reduced photooxidative damage to the cell. Therefore, we propose a model in which adaptive mechanisms related to photosynthetic regulation promote the survival and even blooming of C. nivalis under polar environment, suggesting that C. nivalis can provide organic carbon sources as an important primary producer for other surrounding life in the polar regions for maintaining ecosystem.

“…Biomass transformation is conducted via two different normal procedures: thermochemical decomposition like gasification, bio-carbonization, liquefaction and thermal decomposition (pyrolysis) processes; and also biological nourishment, primarily referring to microbial digestion and digestion. While biological transport is ordinarily very selective and produces quite a few of different services and products in high return utilizing biological catalysts, thermal transformation often supplies multiple and intricate services and products, in rather brief intervals, along with inorganic catalysts are often used to enhance the product quality or spectrum [17].…”

Aim of this paper is to examine the bio-fuels and its assembling. Bio-fuel is any fluid fuel, which is preoccupied or got from bio-materials like trees, grass, crops, farming waste materials. Bio-powers can be delivered from any carbon source that can be re-established for a specific timeframe. Bio-powers are utilized all-inclusive in enterprises and in different spots. It is essential for the world to deliver this vitality in light of the fact that, there is an unfriendly impact on our condition by the use of traditional petro compound energizes. The examination reveals us in brief about bio-fuels and bio-mass, and the strategies for creation of Bio-fuels. The paper discusses the practicalities of creating the biofuels. There are a few advancements from which, we can infer bio-fuels which won't hurt nature, it the inexhaustible wellspring of vitality. Bio-fuels are extremely valuable wellspring of vitality and can be utilized in different fields. These energizes are broadly used to run the vehicle motor, as ethanol is utilized as added substance in gas to build its octane esteem, and to enhance its emanation and biodiesel is utilized in diesel. There are a few strategies made by the administration about the creation of bio-fuels on a huge scale. Government has wanted to build the generation of biofuels about 10%-20% continuously 2030.

“…Thus, algal lipids are expected to act as feedstocks for biodiesels (Chisti, 2007; Hu et al, 2008; Wijffels & Barbosa, 2010). However, the production costs of algal biodiesels are very high compared with those of fossil fuels (Chen, Li, & Wang, 2019). This barrier is likely to be overcome by breeding of high‐performance alga that exhibits fast growth and high‐lipid productivity.…”

“…This barrier is likely to be overcome by breeding of high‐performance alga that exhibits fast growth and high‐lipid productivity. To this end, various studies of algal molecular breeding for the efficient biodiesel production are actively proceeding (Chen et al, 2019; Gomaa, Al‐Haj, & Abed, 2016; Takahashi et al, 2018; Yoshimitsu, Abe, & Harayama, 2018).…”
