“…They can fix atmospheric CO 2 and convert it to biomass through the process of photosynthesis in the presence of sunlight. This preserves several beneficial elements, including carbohydrates, lipids, carotenoids, and some other naturally existing pigments, for use in food production, dietary supplements, animal feed, and the production of healthcare items [21]. Only a small percentage of the 0.2-0.8 million species of microalgae that are thought to exist in nature are studied for research and commercial interests [22,23].…”

The treatment of living organisms is a critical aspect of various environmental and industrial applications, ranging from wastewater treatment to aquaculture. In recent years, algal-based hollow fiber membrane bioreactors (AHFMBRs) have emerged as a promising technology for the sustainable and efficient treatment of living organisms. This review provides a comprehensive examination of AHFMBRs, exploring their integration with algae and hollow fiber membrane systems for diverse applications. It also examines the applications of AHFMBRs in various areas, such as nutrient removal, wastewater treatment, bioremediation, and removal of pharmaceuticals and personal care products. The paper discusses the advantages and challenges associated with AHFMBRs, highlights their performance assessment and optimization strategies, and investigates their environmental impacts and sustainability considerations. The study emphasizes the potential of AHFMBRs in achieving enhanced nutrient removal, bioremediation, and pharmaceutical removal while also addressing important considerations such as energy consumption, resource efficiency, and ecological implications. Additionally, it identifies key challenges and offers insights into future research directions. Through a systematic analysis of relevant studies, this review aims to contribute to the understanding and advancement of algal-based hollow fiber membrane bioreactors as a viable solution for the treatment of living organisms.

“…The production of biofuels such as bio-oil and syngas has been reported when selected streams are subjected to pyrolysis and hydrothermal liquefaction. Biodiesel can be obtained if lipids are transesterified; bioalcohols and biogas can be obtained if biomass is subjected to fermentation and anaerobic (methanogenic) digestion, respectively [47,48]. Narayanan et al [15] reported that the biomass of both microalgae and macroalgae also presents a significant potential for biohydrogen production based on dark fermentation.…”

“…Among the high VAPs that can be obtained from the algal BRF configuration, there are products for human food and animal feed, such as omega-3 and carotenoids, and non-fuel products, such as proteins, pigments (astaxanthin, lutein, echinenone, chlorophyll, and fucoxanthin), carbohydrates and algal extracts used in cosmetics, olefins, and biochar, as well as secondary metabolites (polyphenols, pigments, tocopherols, phytosterols, vitamins, and terpenoids [15,48,49]). Several of these products are value-added compounds [50,51].…”

Biorefineries (BRFs) that process the organic fraction of municipal solid waste and generate bioproducts and bioenergies have attracted attention because they can simultaneously address energy and environmental problems/needs. The objective of this article was to critically review the microbial production of hyaluronic acid (MPHA) and its production profile for its integration into a GBAER-type BRF (a type of BRF based on organic wastes) and to identify the environmental and economic sustainability aspects of the modified BRF that would confirm it as a sustainable option. It was found that the MPHA by selected strains of pathogenic Streptococci was moderate to high, although the trend to work with genetically transformed (GT) (innocuous) bacteria is gaining momentum. For instance, A GT strain of Corynebacterium glutamicum reached a maximum HA production of 71.4 g L−1. MPHA reports that use organic wastes as sources of carbon (C) and nitrogen (N) are scarce. When alternative sources of C and N were used simultaneously, HA production by S. zooepidemicus was lower than that with conventional sources. We identified several knowledge gaps that must be addressed regarding aspects of process scale-up, HA industrial production, economic feasibility and sustainability, and environmental sustainability of the MPHA.

“…vulgaris is ∼20 times higher than the acceptable market price of petroleum-based diesel . Henceforth, co-production of more than one energy form or value-added compound has become the key requisite for a realistic microalgal-based biorefinery framework supporting a circular bioeconomy . A schematic presenting the valorization of algal biomass to produce energy, value-added products, and utilization of deoiled algal biomass has been shown in Figure .…”

The fuel crisis with the slumping reserves of fossil fuels and the exponential increase in the demand of energy necessitate a paradigm shift to a more sustainable and eco-friendly energy system. Microalgal biofuel has been recognized as one of the most prominent and versatile alternative renewable energy sources because it can be converted into a wide array of biofuels, such as biodiesel, bioethanol, bioelectricity and biogases such as syngas, methane, hydrogen, and hythane etc., with a lower carbon emission profile. To attain the economic viability of algal fuels, a collective biorefinery approach addressing both the operational and technical limitations is quintessential. The current review critically analyzes and categorizes energy aspects of microalgae through various direct and indirect approaches with the perspective of a circular economy. These approaches include complicated thermochemical and biochemical processes integrating the recovery of a wide range of value-added products apart from biofuels, thus defining a cascading approach for a multiproduct-based biorefinery model. A glimpse of recent technological advancements comprising hybrid cultivation systems, prospects of co-culturing, and the role of automated/modeling approaches in the industrial-scale production of "algal-based bioenergy" is also discussed in detail. Further, the review has also scrutinized and highlighted the developments and bottlenecks in genetic and molecular aspects of strain improvement for bioenergy production. Furthermore, the study also correlated the socioeconomic and environmental impacts of producing this green energy by evaluating the prospects and pitfalls to obtain a holistic picture on this alternative fuel for a bio-based sustainable economy.
