Antioxidant properties of a novel phycocyanin extract from the blue-green alga Aphanizomenon flos-aquae.
Aphanizomenon flos-aquae (AFA) is a fresh water unicellular blue-green alga (cyanophyta) rich in phycocyanin (PC), a photosynthetic pigment with antioxidant and anti-inflammatory properties. The purpose of this study was to evaluate the ability of a novel natural extract from AFA enriched with PC to protect normal human erythrocytes and plasma samples against oxidative damage in vitro. In red b...
متن کاملCharacterization of a lytic cyanophage that infects the bloom-forming cyanobacterium Aphanizomenon flos-aquae.
Vb-AphaS-CL131 is a novel cyanosiphovirus that infects harmful Aphanizomenon flos-aquae. This cyanophage has an isometric head, 97 nm in diameter and a long, flexible non-contractile tail, 361 nm long. With a genome size of ~120 kb, it is the second largest cyanosiphovirus isolated to date. The latent period was estimated to be ~36 h and a single infected cell produces, on average, 218 infectio...
متن کاملThe Effect of Blue-Green Algae Aphanizomenon Flos-Aquae on Nutrient Assimilation in Rats
Blue-green algae Aphanizomenon flos-aquae (AFA), rich in protein, vitamins, and polyunsaturated fatty acids, are used as food supplements. We studied the effect of varying concentrations (0.05-0.4%) of AFA on growth, feed consumption, and nutrient digestion in rats. A diet supplemented with 0.05% algae (equivalent to human daily consumption) had a stimulatory effect on weight gain and feed cons...
متن کاملInterspecific competition between Microcystis aeruginosa and Anabaena flos-aquae from Taihu Lake, China.
Microcystis and Anabaena are the main cyanobacteria that cause cyanobacterial blooms in Taihu Lake, China. The mechanism of population competition between M. aeruginosa and A. flos-aquae was studied by co-cultivation in the laboratory. The growth of M. aeruginosa was inhibited, while the growth of A. flos-aquae was promoted. The degree of inhibition or promotion was related to the ratio of the ...
متن کاملDraft Genome Sequence of the Toxic Bloom-Forming Cyanobacterium Aphanizomenon flos-aquae NIES-81
Aphanizomenon flos-aquae is a toxic filamentous cyanobacterium that causes water blooms in freshwaters across the globe. We present the draft genome sequence of the A. flos-aquae strain NIES-81, which was determined by 454 pyrosequencing technology. The draft genome is ~5.7 Mb, containing 5,802 predicted protein-coding genes and 58 RNA genes, with a G+C content of 38.5%.
