Received Mar 1; Accepted Dec 2. Seawater cultivation of freshwater cyanobacterium Synechocystis sp. YKT1 grow well when the spring water is supplemented with an inorganic nitrogen source. YKT1, which were comparable to those in an autotrophic synthetic medium. Using complementary approaches to identify trans-domain nuclear gene transfers in the extremophile Galderia sulphuraria Rhodophyta Letter.

Galdieria sulphuraria – Wikipedia

Phycocyanin galdierja used as a natural blue dye in industrial applications. Results Nitrogen and Phosphorus Concentrations in Acidic Hot Spring Water Hot spring water samples from Tamagawa and Tsukahara hot springs in Japan were tested for their applicability to algal cultivation. Key references Ciniglia, C. In addition, the Cyanidiophyceae are tolerant to heavy metals and absorb high concentrations of them from an aquatic environment Nagasaka et al.


SH; wrote the paper: Phosphorus is an essential nutrient for all organisms and has made a major contribution to agricultural and industrial development. The physiological ecology of Cyanidium caldarium. In order to deal with high heavy metal concentrations in its environment, G. Evaluation of three Spirulina species grown under similar conditions for their growth and biochemical. Cells cultured in MA OD of 1. Pisciarelli, Phlegrean Fields, Naples, Italy.

Grown autotrophically, the photosystems of G. Trophic status evaluation for Lakes in Quebec, Canada: Determination of ammonia and Kjeldahl nitrogen by indophenol method.

Thermophiles Acidophiles Species described in Cyanidiophyceae. To overcome this issue, one strategy is to combine acidophilic algae and acidic drainage in which other organisms are unable to thrive.

It is found in naturally acidic hot springsin solfataric environments, and in polluted environments; [3] It galldieria also found in endolithic ecosystemswhere light is scarce and its heterotrophic metabolic capacities are particularly important. Algae and Cyanobacteria in Extreme Environments. The red alga G. YKT1 is able to utilize all three of these nitrogen sources.

These results indicate that P.

Acidic water was collected from the Tsukahara Yufu, Oita prefecture and Tamagawa Senboku, Akita prefecture sulfuric hot springs in Japan. This page was last galdieroa on 5 Julyat By means of gyration in Erlenmeyer flasks, cells entered into the stationary phase 3 weeks after the inoculation and the yield was 2.


Although most red algae use floridean starch as a storage glucanG. In addition, the challenge in using natural water is to avoid impinging upon agriculture and domestic use. Geochemical interpretation of long-term variations in rare earth element concentrations in acidic hot spring waters from the Tamagawa geothermal area.

Consistent with these previous studies, both G. Over 50 different carbon sources suophuraria support growth have been reported.

It was shown that G. Therefore, chemical buffers and pH regulators have been used to prevent a decrease in pH. Its ability to survive in extreme environment as well as its production of phycocyanin PC have made G. The bar indicates the standard deviation of three independent experiments. The nitrate NO 3 – concentration in Ta galdieris Tsu was below the detection limit. SH, S-yM; performed the experiments:
