Short communication: Effect of light and nitrogen concentration on the growth and lipid content of marine diatom, Chaetoceros calcitrans
The effects of light intensity (µ mol m-2 s-1) and different levels of Nitrogen was made on the biomass and lipid of microalgae Chaetoceros calcitrans under laboratory conditions in the north of Iran in 2016. The pure strand of C. calcitrans with F/2 media (8 sets of 3 flasks) were placed in front of the light source at values of 80, 160, and 240 µ mol m-2 s-1. The cell count was collected in ...
متن کاملEffect of growth rate and CO, concentration on carbon isotopic fractionation by the marine diatom Phaeodactylum tricornutum
The carbon isotopic composition (813C) of the marine diatom PhaeodactylurY1 tricomutum was measured over a series of growth rates (p) in a chemostat system in which both the Si3C and the concentration of aqueous CO, [CO,(aq)] were measured. CO,(aq) ranged from 0.64 to 35 pmol kg-l and growth rates from 0.5 to 1.4 d-l. eP, the biological fractionation factor associated with carbon fixation, was ...
متن کاملNitrate Utilization by the Diatom Skeletonema costatum
Nitrate uptake has been studied in nitrogen-deficient cells of the marine diatom Skektowema costatum. When these cells are incubated in the presence of nitrate, this ion is quickly taken up from the medium, and nitrite is excreted by the cells. Nitrite is excreted following classical saturation kineffcs, its rate being independent of nitrate concentration in the incubation medium for nitrate co...
متن کاملBiodecolorization and Biodegradation of Azo Dye Reactive Orange-16 by Marine Nocardiopsis sp.
Background: Azo dyes are xenobiotic compounds that have bioaccumulated in the environment due to escalated industrial development. These are hazardous in nature, possessing carcinogenic and mutagenic effects on human beings. Objectives: The perspective of the present study was to isolate and to determine azo dye (Reactive Orange-16) degrading potential of...
متن کاملSuperductile, Wavy Silica Nanostructures Inspired by Diatom Algae
Biology implements intriguing structural design principles that allow for attractive mechanical properties—such as high strength, toughness, and extensibility despite being made of weak and brittle constituents, as observed in biomineralized structures. For example, diatom algae contain nanoporous hierarchical silicified shells, called frustules, which provide mechanical protection from predato...
