Microalgae are considered to be an important and sustainable alternative fish oil as a source for the polyunsaturated fatty acids (PUFAs) eicosapentaenoic acid (EPA) docosahexaenoic (DHA). Due their health benefits, there is increasing interest in commercial application of these (FA) dietary products, aquaculture feeds. However, FA from microalgae still expensive produce compared or plant oils. With only few microalgal strains being cultivated on large scale PUFA production, prospecting new,...
Microalgae could provide a sustainable alternative to fish oil as source for the omega-3 polyunsaturated fatty acids eicosapentaenoic acid (EPA) and docosahexaenoic (DHA). However, growing microalgae on large-scale is still more cost-intensive than production, outdoor productivities vary greatly with reactor type, geographic location, climate conditions species or even strains. The diatom Phaeodactylum tricornutum has been intensively investigated its potential in due robustness...
Although bacteria are commonly co-occurring in microalgal cultivation and production systems, little is known about their community structure how it might be affected by specific groups or growth conditions. A better understanding the underlying factors that determine of bacterial populations not only important for optimizing processes, but also context product quality when algal biomass to used future food feed. We analyzed composition associated with nine strains stock culture, maintained...
Introduction The incorporation of microalgae in food products is dependent on their volatile profiles, which significantly influence organoleptic characteristics and, consequently, consumer acceptance. However, contain a myriad compounds, and precise impact olfactory gustatory perception not easily inferred. Nonetheless, volatiles imparting fish-like odour are generally considered undesirable. To develop enzyme processes or other methods targeting malodour they must be identified quantified...
We have searched for special characteristics in growth, protein expression, fatty acids and volatile organic compounds (VOCs) a local Phaeodactylum tricornutum Bohlin strain (Bergen Marine Biobank), by comparing it with common accession (CCAP). Differences growth expressed proteins were detected between the BMB CCAP strain, reached highest cell densities under given conditions. Fatty acid (FA) analyses showed relative eicosapentaenoic (EPA) levels exponential phase (25.73% 28.31%), of...
The use of microalgae as a food ingredient has been gaining attention in recent years due to its nutritional benefits. main goals this study were (i) assess the potential Chlorella vulgaris, Tetraselmis chuii, Microchloropsis gaditana, and Phaeodactylum tricornutum; (ii) evaluate their bioactive properties (antioxidant activity, total phenolic content, α-amylase inhibitory activity) (iii) volatile compounds composition. protein content was considerably high (32–44 mg/100 g dw) for all...
Microalgae with a high content of the omega-3 polyunsaturated fatty acids (PUFAs), eicosapentaenoic acid (EPA) and docosahexaenoic (DHA) are great demand for microalgae-based technologies. An Arctic strain diatom Attheya septentrionalis was shown in previous experiments to increase its EPA from 3.0% 4.6% dry weight (DW) nutrient-replete exponential phase nutrient-depleted stationary phase, respectively. In present study, factorial-design experiment used, investigate this effect more detail...
Replacing the large amounts of chemical fertilizer with nutrients from waste or residual streams is an important factor to make microalgal production more sustainable, cost-effective, and part a circular bioeconomy. This first study investigate insect frass as potential nutrient source for cultivation, its effect on protein content microalgae Chlorella vulgaris. When grown extracted frass, C. vulgaris grew equally well showed similar high (40 % dry weight) when in control medium based...
