The qualified presumption of safety (QPS) approach was developed to provide a regularly updated generic pre-evaluation the biological agents, intended for addition food or feed, support work EFSA's Scientific Panels. It is based on an assessment published data each agent, with respect its taxonomic identity, body knowledge, concerns and antimicrobial resistance. Safety identified unit (TU) are, where possible, confirmed at strain product level, reflected by 'qualifications'. In period...
This report presents the results of an analysis technological and market developments in field micro-algal production systems, especially for food feed products. Based on literature search interviews survey to experts, provides current state-ofthe- art microalgae as systems producing food/feed products discusses future challenges Europe become a key player this field.

The qualified presumption of safety (QPS) process was developed to provide a assessment approach for microorganisms intended use in food or feed chains. QPS is based on an published data each taxonomic unit (TU), with respect its identity, the body relevant knowledge and concerns.

Abstract The heterotrophic marine alga Crypthecodinium cohnii is known to produce docosahexaenoic acid (DHA), a polyunsaturated fatty with food and pharmaceutical applications, during batch cultivation on complex media containing sea salt, yeast extract, glucose. In the present study, fed‐batch was studied as an alternative fermentation strategy for DHA production. Glucose acetic were compared carbon sources. For both substrates, feed rate adapted maximum specific consumption of C. cohnii....
An algae-based biorefinery relies on the efficient use of algae biomass through its fractionation in several valuable/bioactive compounds that can be used industry.
Several cell disruption methods were tested on Nannochloropsis gaditana, to evaluate their efficiency in terms of disintegration, energy input and release soluble proteins. High-pressure homogenization (HPH) bead milling the most efficient with >95% ±50% (w/w) total proteins low (<0.5kWh.kg-1biomass). Enzymatic treatment required (<0.34kWh.kg-1biomass), but it only released ±35% protein (w/w). Pulsed Electric Field (PEF) was neither energy-efficient (10.44kWh.kg-1biomass) nor successful for...
A mild biorefinery process was investigated on the microalga Nannochloropsis gaditana, to obtain an enriched fraction of water soluble proteins free from chlorophyll. After harvesting, a 100g.L-1 solution cells first subjected cell disruption by either high-pressure homogenization (HPH) or enzymatic treatment (ENZ). HPH resulted in larger release (49%) aqueous phase compared Alcalase incubation (35%). In both cases, ultrafiltration/diafiltration (UF/DF) then performed supernatant obtained...
The use of a single controlled bead milling step the microalga Tetraselmis suecica resulted in soluble fraction, rich functional proteins. This was achieved by fine-tuning processing time, thereby exploiting difference rates protein and carbohydrate release during milling. Soluble proteins were extracted under mild conditions -room temperature, no addition chemicals, pH 6.5-, with yield 22.5% specific energy consumption 0.6 kWh kgDW-1, which is within recommended minimum for an extraction...

Competition for sulfate and ethanol among Desulfobacter, Desulfobulbus , Desulfovibrio species isolated from estuarine sediments was studied in energy-limited chemostats. baculatus the most successful competitor limiting amounts of ethanol, followed by propionicus. The success dependent on availability sufficient iron. Of three studied, Desulfobacter postgatei least sulfate. Although stimulating growth addition Ca-saturated illite particles to culture media did not affect outcome competition...
The objective of this work was to identify industrial scenarios for the most promising microalgal biorefinery value chains on basis product selection, yields, and techno-economic performance, using biological characteristics algae species. development, creation, validation several new processing routes with applications in food, aquafeeds non-food products were particularly considered work. performance various single (SP) multiproduct (MP) evaluated four strains. Cost-revenue optimization...
