“…species was chosen due to their greater palmitic acid content compared to the alternative forms of microalgae species that have previously been assessed for producing hydrocarbons. In another study [18] Cosmarium sp. was cultivated in a bold basal medium under controlled conditions and the biochemical characterizations were investigated in terms of their suitability for the production of biodiesel and ethanol.…”

The individual and combined effects of micronutrients and hormones on freshwater-borne microalgae growth were investigated for biofuel feedstock in this experimental study. Five algal strains of Chlorella sp., Chlorococcum sp., Phormidium sp., Chlorella sp. and Cosmarium sp., AZH, AZS, ZAA1, ZAA2, and ZAA3, respectively, have been investigated. These strains were treated using different concentrations of micronutrients (iron chloride, manganese chloride, and sodium molybdenum oxide) and hormone (salicylic acid). The different treatments’ growth effects were as follows: iron chloride > sodium molybdenum oxide ˃ manganese chloride > salicylic acid. The order of the increases in the number of microalgal strain cells achieved by the application of the micronutrients and hormone was AZH > AZS > ZAA3 > ZAA2 > ZAA1. The combined treatments produced higher growth rates than the individual treatments, with the order of their effects being micronutrients + hormone > all three micronutrients > hormone alone. The increase in the number of microalgal strain cells under combined treatment was ZAA3 > AZH > AZS > ZAA2 and assessed using one-way ANOVA.

The rapid expansion of the aquaculture industry is accompanied by high organic and nutrient loadings from formulated feeds. This leads to water deterioration and pathogenic microorganisms. Natural biota (e.g., bacteria, phytoplankton, zooplankton, and zoobenthos) in ponds form important parts of cultured aquatic animals’ diets. They contain essential proteins, lipids, carbohydrates, amino acids, and fatty acids and are considered promising supplementary nutrition sources for cultured aquatic animals. Particularly, they are available to aquatic animals throughout the day, and an adequate supply of them as starter foods during the larvae stage ensures high survival. Since formulated feeds constitute more than 50% of aquaculture production costs, optimizing the utilization of natural biota and reducing dietary nutrient input without compromising animals’ growth should be a priority to improve the economic success and sustainability of aquaculture. From this scenario, the present review offers an updated view of the natural biota category in aquaculture systems, their nutritional components, and their contributions to the growth of cultured aquatic animals. Taken together, this review emphasizes the significant roles of natural biota playing in the growth of aquatic animals and encourages maximizing utilization of natural biota to improve feed conversion efficiency and aquaculture sustainability.

“…Municipal-wastewatergrown Tetraselmis suecica was found to be better for ethanol production than the former one. Manoj et al [12] worked on ethanol production from defatted residues of Cosmarium (freshwater green alga), using Saccharomyces cerevisiae during fermentation. Further, they used this alga for biodiesel production.…”

“…In addition, biomass and its chemical composition differ amongst different species and cultivars/subspecies. Biomass consists of a high percentage of carbohydrates, which is a source of ethanol production, whereas high fatty acids/lipids generate diesel [11,12]. In contrast, the excessive exploitation of land resources for biomass has led to forest, land and soil degradation [9].…”

Overuse of non-renewable fossil fuels due to the population explosion urges us to focus on renewable fuels such as bioethanol. It is a well-known fact that ethanol is useful as a blending product with common fuels such as petrol and diesel. This reduces the cost besides bringing down environmental pollution. Apart from chemical methods, bioethanol is generated from photosynthetic plants including algae, plant-based products, microbial organisms and their waste. Specifically, the production of ethanol from microalgal sources has been an attractive method in recent days. The reason behind using microalgal species is their simple structure with photosynthetic ability. In contrast, certain algal species often go disused in some regions. Hence, the production of ethanol from algal sources is one of the best waste management practices. Moreover, it is easy to improve the biomass in microalgal species by altering the physicochemical conditions such as light, pH, temperature, external supply of nutrients, vitamins, nano-sized particles, gene alterations etc., which will enhance ethanol production. In this review, the methods used for ethanol production are discussed. In addition, the factors involved in algal growth and ethanol production are emphasized. Overall, this review focuses on ethanol production from various algal species. This information will be useful for industrial-level production of ethanol and future renewable energy research.
