The present study was designed to synthesize and evaluate the analgesic of hybrid molecules (mutual prodrugs) of tramadol with ibuprofen, diclofenac sodium, and mefenamic acid. Analgesic activity was assessed on albino rats by using the tail-flick method. Synthesized mutual prodrugs were characterized by carbon, hydrogen, and Nitrogen analysis, inf...

The separation of multiple products from microalgae using a biorefinery approach is essential for the economic sustainability of microalgae‐based products. In the current study, a technique for the simultaneous extraction of such products was investigated for the complete valorization of microalgae biomass. Three principal metabolites – chlorophyll...

In our current work, we have optimized six physicochemical parameters (light intensity, light period, pH, inoculum size, culture period, and salt concentration) toward growth and chlorophyll synthesis using isolated fresh water microalgae Chlorella thermophila [contains ∼6% (w/w on dry biomass basis) chlorophyll]. Here, both experimental and comput...

The production of multiple products from microalgae is essential for economic sustainability and the knowledge of optimum cultivation conditions for high growth and biomolecule synthesis of a microalgal strain is the prerequisite for its commercial production. In this work, optimization of nutrient concentrations for the cultivation of isolated Chl...

Algae produce diverse nature of valuable biomolecules that can be broadly categorized as carbohydrates, proteins, pigments, and lipids. Several research studies have been done to establish efficient extraction processes of the biomolecules from algae in the bio-refinery approach with the emphasis on economic feasibility at an industrial scale. In t...

Interest in producing biofuel from microalgae has increased significantly over the years. The choice of suitable microalgal strain is one of the key factors for the economical production of biofuel on large scale. This chapter deals with the choice of different kinds of microalgal strains promising for the biofuel production. These are native micro...

Optimum light exposure for the cultivation of microalgae to obtain high biomass density varies between different species. In the current work, isolated microalgae strain Chlorella thermophila was used to investigate the growth and biomolecular content under exposure of various light regimes in a pilot-scale flat plate photobioreactor (50 L). Here,...

Microalgal biomass is composed of different valuable metabolites that can satisfy the requirements of renewable biofuels, alternative proteins, carbohydrates, and food grade natural colorants. Production of a specific product from microalgae has been proved to be economically infeasible on the commercial scale except for the production of high-valu...

Chlorophylls and carotenoids can be extracted from microalgae using various solvents. However, there is lack of studies regarding the comparison of extraction yield of these pigments from wet and dry microalgal biomass using different combination of cell disruption methods. Therefore, in this work, we have investigated the comparison of the extract...

Microalgae are photosynthetic microscopic organisms, which became popular worldwide due to the promising resource of sustainable and clean energy production with economic and environmental benefits. In this study, one microalgae strain, Podohedriella sp. (MCC44), was isolated from the paddy field, located in Gomati district of Tripura state (northe...

Microalgae possess plenty of useful metabolites (broadly carbohydrate, proteins, pigments, and lipids) that can be converted into commercially useful products. Microalgal cells contain a large quantity of structural and functional carbohydrates, as well as bio-functional proteins and peptides. Downstream processing of these individual metabolites f...
