“…Three species were chlorophytes: the freshwater Haematococcus pluvialis isolated from Bah ıa Blanca (Argentina), 34 Scenedesmus acutus (PVUW12) collected from a wastewater treatment plant, 35 and Neochloris oleoabundans (UTEX 1185), another freshwater microalga, acclimated to marine conditions. 36 The other four species were marine diatoms (Class Bacillariophyceae): Navicula gregaria, 37 Skeletonema costatum, 37 Navicula cincta, 38,39 and Halamphora coffeaeformis, 24,40 which were isolated from the inner zone of Bah ıa Blanca Estuary (38 45S, 62 22W). Stock cultures of these species are maintained at the Laboratorio de Estudios B asicos y Biotecnol ogicos en Algas (LEBBA), CERZOS-CONICET, Bah ıa Blanca, Argentina.…”

In the search for energy sources to replace fossil fuels, microalgae have shown promising characteristics. Their cultures have several advantages over the conventional crops used for commercial biodiesel: they have fast growth rates and a high lipid content and can grow in environments unfit for agriculture. However, relatively few species have so far been studied as biodiesel feedstock. In order to facilitate the search for potentially useful species/strains, in this work, a bioprospecting tool based on biomass and oil production process requirements, triacylglyceride content, and biodiesel properties has been developed. For this purpose, an overall score (OS) was proposed as a tool based on biological, economic, and environmental factors. By applying the OS to nine species, we were able to narrow down the number of species within the diatom group, which are potentially suitable for large-scale biodiesel production. Halamphora coffeaeformis, Navicula cincta, and N. gregaria were the species with the highest OS (1.65-1.5). It is expected that this tool will provide a useful contribution to the criteria applied in the selection of microalgal species for large-scale biodiesel production.

“…This needs to encompass not only what the material is (taxonomically), preferably down to strain (breed) level, as significant variability in various characteristics have been recognised within species, but between strains, but also where the material comes from, who the producer and/or supplier is and what processes may have been used in the ingredient's production [19]. Across each of the three main taxonomic groups examined (microalgae, fungi and bacteria) there has been, arguably, a predominance of work with microalgae [14,15,20,21]. Despite the predominance of work with microalgae, there has also been considerable application of both yeasts and bacteria as protein, lipid or bioactive resources.…”

Single-cell ingredients (SCI) are a relatively broad class of materials that encompasses bacterial, fungal (yeast), microalgal-derived products or the combination of all three microbial groups into microbial bioflocs and aggregates. In this review we focus on those dried and processed single-cell organisms used as potential ingredients for aqua-feeds where the microorganisms are considered non-viable and are used primarily to provide protein, lipids or specific nutritional components. Among the SCI, there is a generalised dichotomy in terms of their use as either single-cell protein (SCP) resources or single-cell oil (SCO) resources, with SCO products being those oleaginous products containing 200 g/kg or more of lipids, whereas those products considered as SCP resources tend to contain more than 300 g/kg of protein (on a dry basis). Both SCP and SCO are now widely being used as protein/amino acid sources, omega-3 sources and sources of bioactive molecules in the diets of several species, with the current range of both these ingredient groups being considerable and growing. However, the different array of products becoming available in the market, how they are produced and processed has also resulted in different nutritional qualities in those products. In assessing this variation among the products and the application of the various types of SCI, we have taken the approach of evaluating their use against a set of standardised evaluation criteria based around key nutritional response parameters and how these criteria have been applied against salmonids, shrimp, tilapia and marine fish species.

“…Algal oil blended with diesel fuel in 20% ratio completely reduced hydrocarbon exhaust and was claimed to be perfect alternative for diesel engine [ 76 ]. Naresh and Prabhakar [ 77 ], also reported the exact 20% blending of algal oil ended with better emission characteristics strikingly it has to be noted most of the research papers defends blending of diesel with 20% algal oil [ 78 ]. Biodiesel yield from N. cinta with B10 and B7 blending pattern was of good cetane value (50–51) [ 79 ].…”
