“…The manipulation of culture conditions or genetic engineering approaches are widely used to increase targeted compounds such as lipids, pigments, proteins and PUFAs from microalgae (Sreekumar et al, 2018). One of the most widely used approaches is enhanced the cultivation of microalgae or biomass production.…”

Plant growth substances could be stimulating algal growth rate and alter lipid compositions. In the present study, we tested hypothesis that exogenous gibberellin (GA) has any effect on growth rate and some fatty acid profiles in green algae Chlorella vulgaris. In Bold Basal Medium with 100 µM GA 3 , cell density increased to 68.57% on third day as compared to the control cells. These results indicated that GA 3 enhanced microalgal growth and cell size. The lipid profile was also altered compared to control using Gas Chromatography-Mass Spectrometry (GC-MS). GA 3 promotes the production of C16:0, C18:0, C18:1 and C18:3 on day-3 and-5. Under nitrogen starvation condition, application of GA 3 provide enhanced algae growth and stimulated C16:0 and C18:1 production. In conclusion, this study demonstrated that gibberellin could be a good candidate as a hormone for increasing lipid production in microalgae culture system.

“…Pulz and Gross (2004) observed that: "successful algal biotechnology mainly depends on choosing the right alga with relevant properties for specific culture conditions and products" [19]. The basic criteria of selection will vary from lipid productivity, growth rate, land consumption, to even economics based on the method of cultivation and output requirements [20], [21]. Around 3,000 species are isolated and screened in the Aquatic Species Programme [11], several of these are potential candidates for algal oil production in open ponds and can be used to consume carbon dioxide from coal-fired power stations, but a final verdict on a most suitable species is not provided.…”

The fast depleting energy sources and other environmental concerns, like carbon emissions, have led the scientific community on a race against time to find an ecofriendly, sustainable and renewable source of energy. Biofuels obtained from domestic used materials cannot practically satisfy the existing demand for an industrial fuel. Biodiesel is mono-alkyl esters of vegetable oils or animal fats. The major advantage of biodiesel is that it can be used directly into existing engines without any modifications. One of the potential sources for renewable biodiesel production which can effectively supply biodiesel for international and industrial demand is microalgae. Besides production of biofuels microalgae have been seen as a potential source for a number of areas including pharmaceuticals, nutrition and aquaculture. This review discusses on the different aspects, challenges and current scenario in the biodiesel production from microalgae. Cultivation of a high yielding marine microalgal strain in a very economical and well scrutinised open raceway pond could prove to be the key to future of energy sector. Various lipid enhancement methods and proposed culture methods are also discussed. On an industrial perspective, a well-engineered and continuously monitored open raceway pond for cultivation of marine micro algae seems to be a promising economically viable method for production of biofuel.

Biodiesel is one the few substitute energizes, which has the capability of being utilized as a fuel to encourage ignition process in vehicles. In any case, the better properties of biodiesel over the greater part of the other exchange powers accessible have made it the most positive fuel than supplant the ordinary diesel. As indicated by the investigations, it has been seen that biodiesel has better execution attributes when contrasted with diesel. It very well may be effectively delivered utilizing procedures, for example, direct use and mixing, smaller scale emulsions, warm splitting (pyrolysis) and transesterification. It is likewise to be seen that it tends to be gotten from sources, for example, vegetable oil, squander cooking oil, creature fat, and waste fuel. Along these lines, it very well may be seen that biodiesel can be effectively acquired. In this audit, the procedure of biodiesel creation, its focal points and the burdens of biodiesel fuel has been talked about.
