The process of creating a sustainable future entails technique that simultaneously meet the needs of the present and future generations. The interdisciplinary area of nanobiotechnology blends biotechnology and nanotechnology to produce novel solutions for a range of applications. This field investigates the manipulation and regulation of the biolog...

In this study, carbon dots were synthesized using a green approach from defatted biomass of microalga Coelastrella sp. The entire process is extremely promising due to its non-toxic and environment-friendly nature. It demonstrated a sustainable approach for the biogenic synthesis of C-dots using lipid extracted biomass residue of microalgae Coelast...

Biomass has long been utilized in the production of food, animal feed, and other industrial goods.

Microalgae are considered as potential source to treat the wastewater and utilize the harvested biomass to produce biofuels.

Microalgae are a diverse group of organisms that can be found in various environments. They differ according to their habitats and metabolite synthesis. Microalgae isolation and purification are critical steps in their biotechnological uses. The goal of algae isolation and purification is to obtain axenic cultures or viable cultures of a single spe...

A few strains have been commercially used so far for the creation of fine chemicals, nutraceuticals, food additives, and aquaculture feed. The classification of algae has eluded applied phycologists. In this chapter, we aim to throw a light on classifying microalgae in a hierarchical, phylogenetically relevant manner, and we attempt to solve this...

Three major modes of cultivation are discussed in the following section: photoautotrophic, heterotrophic, and mixotrophic.

Depending on the type of biomass, the alternatives for conversion, and the intended use of the energy, there are various ways for turning algae into energy.

Microalgae are considered as the potential candidate for the biodiesel and energy source.

Harvesting of microalgae biomass is the major bottleneck in biofuel technology, and it counts for one third of the total cost. Harvesting of microalgae is tedious process due to the small size of the cells and low density of culture suspension.

The persistent fight against global environmental threats and energy catastrophe is currently a major concern for the economic development of bioenergy across the entire country. Hence, traditional fuel-based reserves are overburdened to cope with the rapid energy crisis, necessitating an urgent need for an innovative carbon-neutral green-energy re...

Sugarcane spent wash generates waste at a large scale that impacts the environment, hence the classic waste reuse technology needs to be implemented. An integrated approach of spent wash and microalgae cultivation to produce biodiesel has gained momentum in recent times. However, the microalgae technology lacks the functional utilization of de-oile...

An expeditious pace of expanding industrialization and urbanization is a global vulnerability which immediately requires utmost attention towards the replacement of prosaic petroleum-based polymer assimilation. Thus, greening the innovative route of microalgae derived biopolymers has attained significant interest as an improved and sustainable appr...

Algae are photosynthetic organism found in freshwater, marine, and soil habitats. The major advantages of algae is their rapid growth, high metabolic adaptations, tolerance toward unfavorable conditions, and the production of valuable compounds. Algae are a potential feedstock for the production of biofuel with high value-added products including p...

High cultivation cost and low lipid yield are framed as a major bottleneck for the production of microalgae biodiesel. Hence, we first and foremost highlight a trophic mode transition, coupled with a combinatorial effect of organic carbon, nitrogen and light (C/N/L) on an isolated microalga Chlorococcum sp. SVF in a one pot tri-phasic intermittent...

Microalgae have been considered as a potential feedstock for biodiesel production, since its cultivation uses less land than other traditional oil crops and has a higher growth rate. A great challenge is a choice of an effective approach for microalgae biomass recovery and lipid extraction, since the scheduling of these practices are critical and r...

Present investigation highlighted the capability of microalgae cultivation in sewage wastewater integrated with nanomaterial, addressing wastewater treatment and consequent improvement in lipid for biodiesel application. Herein, the isolated microalga Chlorosarcinopsis sp. MAS04, was cultured in primary treated wastewater (PTWW) and secondary treat...

Present study aimed to evaluate the influence of carbon/nitrogen ratio (C/N) on mixotrophic growth of microalgae and role of nanomaterial in cell recovery and lipid improvement. In this study, three microalgae species were isolated, screened from local freshwater body for lipid assimilation. The microalgae were identified as Chlorococcum sp., Scene...

Herein, zirchonium di-oxide nanoparticles (ZrO2-Nps) were selected best for cell recovery and lipid extraction for microalgae Chlorococcum sp. Optimization of ZrO2-NPs concentrations by varying time intervals was done to achieve maximum cell recovery. The flocculation efficiency of 99.59% was achieved at the elevated pH (pH 10) providing 15 mg/L of...

To reduce the cost of media components and consecutively enhance the amount of lipid formation, the effect of crude glycerol on Euglena gracilis is reported for the first time. Presently, E. gracilis has been chosen because of excellent capability of its growth and lipid synthesis in mixotrophic culture condition on organic carbon sources (Glucose...

Electromagnetic waves are used in today lives and spreading the environmental factor. We need visible light to see, radio waves for telecommunication and x-ray for medical purpose. Electromagnetic radiations are used for its bactericidal effect. It affects the cellular mechanism, cell membrane and might increase or decrease the activity of protein....
