Genome of the red alga Porphyridium purpureum
The limited knowledge we have about red algal genomes comes from the highly specialized extremophiles, Cyanidiophyceae. Here, we describe the first genome sequence from a mesophilic, unicellular red alga, Porphyridium purpureum. The 8,355 predicted genes in P. purpureum, hundreds of which are likely to be implicated in a history of horizontal gene transfer, reside in a genome of 19.7 Mbp with 2...
متن کاملRecovery of pure B-phycoerythrin from the microalga Porphyridium cruentum.
Phycoerythrin is a major light-harvesting pigment of red algae and cyanobacteria that is widely used as a fluorescent probe and analytical reagent. In this paper, B-phycoerythrin and R-phycocyanin in native state, from the red alga Porphyridium cruentum were obtained by an inexpensive and simple process. The best results of this purification procedure were scaled up by a factor of 13 to a large...
متن کاملStable chloroplast transformation of the unicellular red alga Porphyridium species.
Red algae are extremely attractive for biotechnology because they synthesize accessory photosynthetic pigments (phycobilins and carotenoids), unsaturated fatty acids, and unique cell wall sulfated polysaccharides. We report a high-efficiency chloroplast transformation system for the unicellular red microalga Porphyridium sp. This is the first genetic transformation system for Rhodophytes and is...
متن کاملMicrowave-assisted extraction of phycobiliproteins from Porphyridium purpureum.
In the present study, microwave-assisted extraction was first employed to extract the phycobiliproteins of Porphyridium purpureum (Pp). Freeze-dried Pp cells were subjected to microwave-assisted extraction (MAE) to extract phycoerythin (PE), phycocyanin (PC), and allophycocyanin (APC). MAE combined reproducibility and high extraction yields and allowed a 180- to 1,080-fold reduction of the extr...
متن کامل5-Aminolevulinic acid promotes arachidonic acid biosynthesis in the red microalga Porphyridium purpureum
BACKGROUND The microalga Porphyridium purpureum within Rhodophyta abundantly produces several valuable proteins, polysaccharides, pigments and long-chain polyunsaturated fatty acid; it is especially effective in accumulating arachidonic acid (ARA). However, this high ARA yield is always achieved in conditions unfavourable for cell growth. In this study, we present a method for obtaining desirab...
