Auxenochlorella Protothecoides

In recent years, there has been growing interest in the biomass of unicellular algae as a source of valuable metabolites. The main limitations in the commercial application of microbial biomass are associated with the costs of production thereof. Maize silage is one of the main substrates used in biogas plants in Europe. The effects of sterilized agricultural liquid digestate (LD) from methane fermentation of maize silage on the growth rates, macro and micronutrient removal efficiency, lipid content, and fatty acid profile in Auxenochlorella protothecoides were investigated. The results indicate that A. prothecoides can proliferate and accumulate lipids with simultaneous reduction of nutrients in the 1:20 diluted liquid digestate. The rate of nitrogen and phosphorus removal from the liquid digestate was 79.45% and 78.4%, respectively. Cells growing in diluted liquid digestate exhibited the maximum lipid content, i.e., 44.65%. The fatty acid profile of A. prothecoides shows a decrease in the content of linolenic acid by 20.87% and an increase in oleic acid by 32.16% in the LD, compared with the control. The liquid digestate changed the content of monounsaturated fatty acids and polyunsaturated fatty acids. The cells of A. protothecoides growing in the liquid digestate were characterized by lower PUFA content and higher MUFA levels.

Effect of Pasture or Maize Silage Feeding on the Nutritional Value of BeefThe objective of this study was to evaluate the nutritional value of beef from different production systems. The study was conducted with Hereford bulls on organic and conventional farms. On the organic farm, fattening was mainly based on roughages, including pasture forage in the summer season, when the end of fattening occurred. On the conventional farm the bulls were fed maize silage and concentrate. On both farms, the animals were aged 7-9 months at the beginning of fattening. The bulls were fattened to a final body weight of 550-600 kg. Samples of longissimus thoracis muscle were collected from half-carcasses of slaughtered bulls originating from each farm to analyse fat content, fatty acid profile, and content of selected minerals and vitamin E. Muscle samples were additionally analysed for the concentration of thiobarbituric acid-reactive substances 3 and 7 days after slaughter. Analyses showed a lower fat content in longissimus thoracis muscle of bulls from the pasture feeding system. The fatty acid profile was also characterized by a lower content of C 14:0, and a higher content of polyunsaturated fatty acids (PUFA), including C18:3 n-3, conjugated linoleic acid, C 20:5 n-3, and C 22:5 n-3, as well as by a lower ratio of n-6/n-3 PUFA. The total content of monounsaturated fatty acids was significantly higher in animals fed maize silage and feed concentrate. In turn, the muscle of pasture fed animals had higher levels of Na, Zn and Fe as well as of vitamin E.

Key Species

Pleuroncodes monodon, an important fishery resource and key species in the Humboldt Current Large Marine ecosystem, has a prolonged reproductive period from winter until end of summer, and during this time females incubating their embryos are exposed to seasonal variation in food availability and in temperature. Additionally, in order to ensure successful reproduction and survival of embryos, changes occur in the main internal reserves and/or sources of energy of P. monodon. The aim of this study was to determine the extent of seasonal variation (winter vs summer) in the lipid content and fatty acid composition of ovigerous females and their embryos. The results show that a higher percentage of saturated and polyunsaturated fatty acids are found in females in winter. Similarly, the composition of fatty acids in embryos found here indicates that winter embryos have more saturated fatty acids and essential fatty acids (C18:2n6cis, C18:3n6 and C22:6n3) than do summer embryos. According to PCA analysis of fatty acid profile, samples from summer may be distinguished into two isolated groups with conspicuous variations in fatty acids profile of embryo and hepatopancreas. While in winter, the opposite pattern occurs in the fatty acid profile of embryo and hepatopancreas. These variations may be related to relevant physiological processes (reproduction and growth) and of their ontogeny (development and survival of offspring). Seasonal variation in the lipid content and composition of fatty acids of P. monodon could directly impact this species’ reproduction and survival and subsequently could have consequences on the food web and fishery exploitation.

The fortification of feed is known to be a useful tool to manipulate the nutritional value of insects. This study aimed to reveal the effect of carrot supplement duration on the basic nutrients, fatty acid profile, carotenes, and tocopherols. Jamaican crickets (Gryllus assimilis) were provided with chicken feed supplemented with carrots ad libitum for 0, 3, 7, 14 and 60 days prior to harvest. The supplementation increased the levels of α-carotene and β-carotene in the insects. The content of carotenoids did not significantly differ between groups fed carrot for 14 (α-carotene = 13.7 μg/g DM; β-carotene = 34.6 μg/g DM) and 60 days (α-carotene = 15.2 μg/g DM; β-carotene = 37.2 μg/g DM), suggesting that the capacity of the insects to store carotenes is limited. Some carotenoids (α-carotene = 5.4 μg/g DM; β-carotene = 12.8 μg/g DM) were found in crickets given carrot supplementation for only 3 days prior to harvest. Carrot supplementation affected the fatty acid profile of the insects. Crickets fed carrot for 60 and 14 days contained lower levels of SFA (32.00 and 32.74% of total fatty acids respectively) and higher levels of PUFA (33.06 and 32.49% of total fatty acids respectively) in comparison with insects fed for 0, 3 or 7 days. No influence of carrot supplementation was observed in feed conversion, tocopherols and basic nutrients (proteins, lipids, ash). Conclusively, the paper showed some beneficial effects of carrot supplementation, when the highest levels of carotenoids were reached by 14 and 60 days of carrot provision. Therefore, the whole life supplementation seems to be not necessary to reach the increased content of carotenoids in crickets.
