The ability of a recent isolate, Tetraselmis sp. CTP4, for nutrient removal from sewage effluents before and after the nitrification process under batch and continuous cultivation was studied. Biomass productivities in both wastewaters were similar under continuous conditions (0.343±0.053gL-1d-1) and nutrient uptake rates were maximal 31.4±0.4mgNL-1d-1 and 6.66±1.57mgP-PO43-L-1d-1 in WW before ...

in order to compare two hydroponic culture systems (countinuous and pumic) for producing two cultivars of greenhouse cucumber (2259 and delta star) an experiment was conducted in randomized complete block design with five replications. for mineral nutrition of plants murashige and skoog solution (m.s.) was used by concentration of leaves. the height of the stem, diameter of the first internode,...

The tendency of microbiota changes in the soil Ganoderma leucocontextum continuous cultivation is investigated by high-throughput sequencing technology. Medium bag G. with uncultivated significantly increased organic matter (OM), hydrolyzable nitrogen, available phosphorus, and potassium content soil. relative abundance dominant beneficial bacteria (Sphingomonas spp., Mucilaginibacter Bryobacte...

Cultivation of amebae of the axenic strain of Naegleria gruberi, NEG-M, was achieved in media consisting entirely of chemically defined components. A complete medium that contains 31 components allows growth with yields up to 5 x 10(6) amebae per ml. A minimal medium gives lower yields but defines 22 components that are essential for continuous cultivation: 11 amino acids, 6 vitamins, hematin, ...

SUMMARY A human hormone-synthesizing trophoblastic cell system has been established in vitro and may prove to be the first func tional human embryonic cell line in continuous culture. Cho-rionic gonadotropin hormone produced by these cultures serve as a marker for identification of the trophoblastic cell. No interruption in this property nor change in cytologie display has occurred during 1.5 y...

Due to its abundance and also flexibility of cultivation conditions, Chlorella vulgaris microalgae is one of the most ideal options available in order to production of microalgae based biodiesel. Since vulgaris cultivation for fuel production needs economic considerations to be taken, and in first place providing biomass and lipid production costs is important, wide researches have bee...
