“…They are one of the most important alternatives to synthetic pigments applied in food, feed, and pharmaceutical industries. Their biodegradability and compatibility with the environment opened promising avenues for various applications 7,8 and recently, Jannathulla et al 9 reported that the global production of microbial products is expected to increase by 8.6% during the period 2018-2023. Among colorful bacteria or pigment-producing bacteria, purple nonsulfur bacteria (PNSB) constitute a group that has the potential to produce carotenoids.…”

Purple nonsulfur bacteria (PNSB) were investigated for their carotenoid production and anti-vibrio activity against acute hepatopancreatic necrosis disease (AHPND)-causing Vibrio parahaemolyticus. To test carotenoid production, selected strains were cultivated in basic isolation medium (BIM), glutamate acetate medium, G5 medium and artificial acetic acid wastewater (AAW) medium. From 144 PNSB, Rhodopseudomonas palustris KTSSG46 was selected to produce carotenoids under microaerobic light conditions in BIM. When the culture medium was optimized, strain KTSSG46 grown in BIM modified with lglutamate at 1 g/L more effectively inhibited AHPND-causing V. parahaemolyticus strains than standard BIM with 1 g/L (NH 4 ) 2 SO 4 . BIM was further modified with 1.23 g/L MgSO 4 ⋅7H 2 O and carotenoid production increased 40.22%. Carotenoid production at day 2 by strain KTSSG46 grown in BIM modified with l-glutamate at 1 and 1.23 g/L MgSO 4 ⋅7H 2 O was the same as production in BIM modified with monosodium glutamate (MSG). Culture supernatants from all BIM formulations showed similar activity against the resistant AHPND strain SR2. Based on high-performance liquid chromatography, carotenoids of strain KTSSG46 might be canthaxanthin. Grown in BIM modified with MSG, strain KTSSG46 could produce inexpensive carotenoids and release anti-vibrio compounds that, applied as shrimp feed additive, would prevent AHPND strains.

“…As proteins are the main components of the dry mass of bacteria [14] and it is well known that they participate in metal sorption processes, we also analyzed the amino acid composition of the spent biomass (Figure 1). As can be seen, the amino acid profile of the two samples is very similar and typical for whole-cell microbial biomass [15]. The total amount of amino acids in the materials is approximately 500 mg/g, and aspartic and glutamic acid are the dominant amino acids, while cysteine is the lowest.…”

This study investigated the possibility of using the spent kind of biomass of Pseudomonas putida CA-3 and Zobelella denitrificans MW1 obtained after the pilot-scale production of polyhydroxyalkanoates (PHAs) as a biosorbent for the bioremediation of aqueous solutions containing toxic cadmium and lead ions. The material was characterized by means of scanning electron microscopy, Fourier-transformed infrared spectroscopy, nuclear magnetic resonance spectroscopy and amino acid profiling. To check the sorption capacity of spent biomass against Pb and Cd ions, equilibrium studies were performed. To learn about the nature of the sorption process, kinetic modelling was carried out and the obtained results showed that the adsorption process is best described by the pseudo-second-order kinetic model (PSO), which suggests that the sorption process is connected with the chemical bonding of the ions on the sorbent surface. Information provided by the amino acid profile made it possible to predict the adsorption mechanism and FTIR analysis proved the participation of different chemical groups in the removal process. According to the equilibrium studies, the best-fitted isotherm was the Freundlich model for all used materials and metal ions considering the correlation coefficient. Summarizing the results, the spent biomass after the PHA production is an effective biosorbent and can be reused for heavy metal bioremediation.

“…286 The major classes of these microorganisms that have been evaluated for use as aquafeed single-cell ingredients include marine protists like Aurantiochytrium, Schizochytrium and Thraustochytrium, methanotrophic bacteria like Methylobacterium and Methylococcus, chemotrophic proteobacteria like Clostridium and Baccillus, and yeasts like Candida, Cyberlindnera, Kluyveromyces, Rhodotorula, Saccharomyces and Wickerhamomyces. 82,[287][288][289][290][291] Many of these studies have identified various nutrient-rich waste stream resources that can be used as media substrates to cultivate these microorganisms under a CBF for the production of single-cell ingredients include industrial flue or flare off-gases, municipal or industrial waste-waters, agricultural lignocellulosic crop or forestry biomass processing wastes, brewery and distillery by-products, terrestrial food/feed discards and meat, seafood and aquaculture processing wastes, among others. With the industry still in its infancy and just now beginning to up-scale, global production data for single-cell ingredients for use in aquafeeds is difficult to quantify.…”

The aims of this review are to describe the role of 'blue-food production' (animals, plants and algae harvested from freshwater and marine environments) within a circular bioeconomy, discuss how such a framework can help the sustainability and resilience of aquaculture and to summarise key examples of novel nutrient sources that are emerging in the field of fed-aquaculture species. Aquaculture now provides >50% of the global seafood supply, a share that is expected to increase to at least 60% within the next decade.Aquaculture is an important tool for reducing resource consumption in global protein production and increasing resilience to climate change and other global disruptions (i.e. pandemics, geo-political instability). Importantly, blue foods also provide essential nutrition for a growing human population. Blue foods are helping to help the global goal of 'zero hunger' (United Nation's Sustainable Development Goal 2) while reducing the dependency on finite natural resources but further refinement and new solutions are needed to make the industry more 'circular' and sustainable, particularly with respect to sourcing raw materials for aquafeeds. This review describes the feed resources that are available or may be created within a circular bioeconomy framework, their role within the framework and in aquaculture and ultimately, how these resources contribute to de-risking and establishing a resilient aquaculture production chain.
