The current scientific studies have shown that extensive quantities of synthetic pigments are used worldwide in diverse industries. Synthetic pigments have shown enormous toxicity issues compared to natural colorants and dyes in current industrial usage. Diverse microbial communities, including fungi, bacteria, archaea, and yeast are current biopigment producers. However, the aforementioned biopigments are expensive, least efficient, and less eco-friendly to attain industrial sustainability. Thus, algae-based bio pigments are one of the best natural resources to meet today’s challenges. Algal pigments increase the product’s marketability and carry multiple therapeutic properties, including antioxidant, anti-inflammatory, and neuroprotective actions. These multidimensional qualities of algal pigments have piqued the interest of the food, pharmaceutical, cosmetic, and nutraceutical industries resulting in most potential implementation. Thus, a paradigm shift requires identifying potential algal communities having a higher biopigment-producing ability for future manufacturing and commercialization as a sustainable way forward. Hence, the current study has been designed for effective isolation and screening of algal isolates (i.e. DS1, DS2, DS3, DS4, DS5) from a different region of sundarban water resources concerning the investigation of algal pigments (i.e. chlorophyll-a, chlorophyll-b and carotenoid). In a nutshell, the current study shows that DS2 isolate produces a significant quantity of carotenoid (9.729 mg/g DCW), chlorophyll a (7.872 mg/g DCW), and chlorophyll b (7.176 mg/g DCW) amongst all isolates. Hence, the present study reveals that DS2 algal isolates might be a potential predecessor of biopigment production, having pivotal applications in food, pharmaceutical, cosmetic, and nutraceutical industries in the near future.

“…Total chlorophyll measurement had played important role during algae based SCP production as predominant indicator of photosynthesis and biomass generation under broad spectrum of light source and intensity. Moreover, total chlorophyll content in algal SCP had also been enumerated in this present study because it had always considered as essential precursor for biogenesis of diverse ranges of vitamins, antioxidants, and nutraceutical constituents [18,19]. In this present study, on day 12 th , 1 mL of the algal isolate from the batch cultivation was placed into each separated, labeled Eppendorf tubes, and centrifuged for 10 min at 12,000 rpm.…”

“…The comparative study showed that the highest chlorophyll concentration was observed in the DK1 algal isolate [Figure 5]. Thus, higher level of total chlorophyll content had shown a clear indication that DK1 could be very effective algae based SCP having higher antioxidant activity, vitamin content, and higher nutraceutical properties [18,19,22].…”

Human dietary deficiency is one the dismaying question due to consumption of modern readymade foods in today's hectic life pattern. Broad spectrums of population are enforcing them toward malnutrition or nutritional deficiency in developing or underdeveloped countries. Additional nutritious and balanced food sources must be made available to control this present scenario. However, conventional protein-rich resources would not compensate the demand of protein-rich food crops with increase in raising population. In this context, algae could be the potent higher proteinrich food supplements through carbon allocation to algal biomass generation without hampering food chain, and soil resources depletion. Realizing the wide-scale adoption, high protein yielding algal isolates with lowered nucleic acid content and higher chlorophyll content need to be explored considering its toxicity on community health. To this end, the diverse topographical locations of the Kangsabati River have been considered for isolation of broad spectrum of algal regimes to examine quantity of total protein, nucleic acid, and chlorophylls. The present study has depicted that algal isolate DK1 contains highest protein and chlorophyll content in the best on the 12 th day indulging 36% protein and 13% chlorophyll where total nucleic acid amount is very limiting 0.52%. Moreover, a DK1 alga has shown limited pathogenicity through hemolysin assay toward its acceptance for community usage as single-cell protein-rich food supplement and alterative nutraceutical.

“…However, the first-and second-generation biodiesel production approaches require huge areas of arable agricultural lands. To this end, biomass-derived biodiesel generation is a highly beneficial alternative approach due to extensive unique advantages including carbon neutrality, minimized greenhouse gas emission (i.e., carbon monoxide, carbon dioxide, and sulfur oxides), spontaneous cheaper biomass feedstock availability, and biosafety of biomass production through agriculture [24]. To this end, algae are impressive microbial candidates for biodiesel generation as algae grow without competing with the food chain, inherently faster growth rate, and have higher lipid content under diverse nutrient-limiting environments [25].…”

Human civilization faces a huge energy crisis due to climate alterations and reduction in fossil fuel reserves. Biofuels are sustainable platform that can combat this burning issue currently. Biodiesel is a potential fossil fuel alternative from cooking, soybean, or plant-derived oil resources. Existing biodiesel production processes are directly competing with food chain. Algae are impressive alternatives for biodiesel generation as algae grow without competition with food chain, have an inherently faster growth rate, and have higher lipid content under diverse nutrient-limiting environments. Lignocellulosic waste (LCW) accumulation has been increasing through anthropogenic activities. Accumulation of LCW causes ill effects on environment and human health. Thus, a faster paradigm shift needs to be required for establishing a single platform to perform lignocellulosic biomass degradation along with higher lipid production as biodiesel precursor. Few studies show algal endoglucanase or cellulase activities for degrading LCW to generate monomeric constituents which can further be channelized to produce higher biomass and lipid contents as biodiesel precursor. Thus, the present study focuses on a feasibility attempt to show that mangrove algal isolates could be a potential microbial cell factory for cellulose degradation as a major constituent of LCW and higher lipid production as potential precursor for biodiesel production in near future.
