“…In addition, the production technologies applied largely influence production of bioactive compounds [ 24 ], while, in outdoor conditions, the environmental influences cannot be controlled because they vary with the seasons [ 142 ]. In closed conditions (e.g., cultivation in photobioreactor systems), production is triggered by perfectly controlled conditions [ 143 ]. However, outdoor cultivation is normally conducted in extensive conditions and, consequently, is economically more convenient for mass production [ 84 ].…”

The search for novel sources of nutrients is among the basic goals for achievement of sustainable progress. In this context, microalgae are relevant organisms, being rich in high-value compounds and able to grow in open ponds or photobioreactors, thus enabling profitable exploitation of aquatic resources. Microalgae, a huge taxon containing photosynthetic microorganisms living in freshwater, as well as in brackish and marine waters, typically unicellular and eukaryotic, include green algae (Chlorophyceae), red algae (Rhodophyceae), brown algae (Phaeophyceae) and diatoms (Bacillariophyceae). In recent decades, diatoms have been considered the most sustainable sources of nutrients for humans with respect to other microalgae. This review focuses on studies exploring their bio-pharmacological activities when relevant for human disease prevention and/or treatment. In addition, we considered diatoms and their extracts (or purified compounds) when relevant for specific nutraceutical applications.

“…In addition, studies have shown that Cyclotella sp. is the potential to produce chitin microfibers (Chiriboga & Rorrer, 2018;Rorrer et al, 2016), which have applications in biomedical, cosmetics, food preservation, dietary supplements, paper making, and in wastewater treatment (Bhatnagar & Sillanpaa, 2009;Elwakeel, 2010;Jayakumar, Menon, Manzoor, Nair, & Tamura, 2010;Jeon, Shahidi, & Kim, 2000;Morganti & Morganti, 2008;No, Meyers, Prinyawiwatkul, & Xu, 2007).…”

The explosive multiplication of phytoplankton caused by water eutrophication often occur in the intensive shrimp aquaculture. To comprehensively assess the diversity and community structure of phytoplankton in the waters of typical indoor industrial aquaculture system for Litopenaeus vannamei, a combination of high‐throughput sequencing and morphological identification methods were used in the present study. A total of 41 genera belong to nine phyla were detected by both methods. Chlorophyta, Cyanophyta and Bacillariophyta were found to be three dominant phyla. The high‐throughput sequencing revealed that green algae and cyanobacteria were the most dominant phytoplankton; however, diatoms were the first dominant phytoplankton by using the morphological identification. At the genus level, Picochlorum and Synechococcus were dominant, accounting for 20.94%–97.19% and 0.01%–52.81% of total phytoplankton, revealed by the high‐throughput sequencing. Therefore, more attention should be paid to their ecological impacts on the surrounding sea areas or potential toxicity to shrimp. Cyclotella was the most dominant genus revealed by the morphological identification. High‐throughput sequencing revealed a high diversity and small‐sized phytoplankton which were undetected by microscopy. Both methods provide similar information on the environmental drivers of phytoplankton community. NO3−, NH4+, DIP, DSi, DON and DOP concentrations were the main factors influencing the phytoplankton community structure and diversity.

“…The cell surface chemistry plays a vital role in NP production since the cell surface adsorption-reduction of metal cations contributes more to NP synthesis than intracellular NP formation following the metal uptake [ 12 ]. Many studies have reported the cell surface involvement in the production of NPs, as presented in Table 1 [ 72 , 73 , 74 , 75 , 76 , 77 ]. The negatively charged surface groups of the cells, such as hydroxyl, carboxyl, and phosphate, have an affinity for metal cations [ 78 , 79 ].…”

In Vivo Biosynthesis of Inorganic Nanomaterials Using Eukaryotes—A Review

Bionanotechnology, the use of biological resources to produce novel, valuable nanomaterials, has witnessed tremendous developments over the past two decades. This eco-friendly and sustainable approach enables the synthesis of numerous, diverse types of useful nanomaterials for many medical, commercial, and scientific applications. Countless reviews describing the biosynthesis of nanomaterials have been published. However, to the best of our knowledge, no review has been exclusively focused on the in vivo biosynthesis of inorganic nanomaterials. Therefore, the present review is dedicated to filling this gap by describing the many different facets of the in vivo biosynthesis of nanoparticles (NPs) using living eukaryotic cells and organisms—more specifically, live plants and living biomass of several species of microalgae, yeast, fungus, mammalian cells, and animals. It also highlights the strengths and weaknesses of the synthesis methodologies and the NP characteristics, bio-applications, and proposed synthesis mechanisms. This comprehensive review also brings attention to enabling a better understanding between the living organisms themselves and the synthesis conditions that allow their exploitation as nanobiotechnological production platforms as these might serve as a robust resource to boost and expand the bio-production and use of desirable, functional inorganic nanomaterials.
