WebJun 11, 1998 · Net specific growth rates of diatom cells were 0.76 d −1 (Fe-enriched) and 0.40 d −1 (controls). Final concentrations of the diatom-specific pigment fucoxanthin were about three times higher... WebFor both diatoms and other phytoplankton, growth rates decline with increased cell volume, consistent with observations, because the C cost of division increases with size faster than photosynthesis. However, the model predicts overall higher growth rates for diatoms due to reduced C requirements and the low energetic cost of Si deposition.

WebIron fertilization is the intentional introduction of iron to iron-poor areas of the ocean surface to stimulate phytoplankton production. This is intended to enhance biological productivity and/or accelerate carbon dioxide (CO 2) … WebJun 11, 2024 · Diatoms are photosynthetic microalgae that fix a significant fraction of the world's carbon. Because of their photosynthetic efficiency and high-lipid content, diatoms are priority candidates for biofuel production. Here, we report that sporulating Bacillus thuringiensis and other members of the Bacillus cereus group, when in co-culture with ... porsche network

WebOct 16, 2024 · Growth of diatoms during culture Full size image As the culture progressed, diatoms gradually aggregated around the carriers and grew on them (in the middle and late stage of culture), and the edges of the seaweed carriers gradually blurred and the color gradually lightened. WebMar 27, 2024 · Diatoms are photosynthetic eukaryotes that are fundamental to aquatic food chains and fix one-fifth of global carbon. They store the fixed carbon in lipid form, making them desirable organisms for biofuel production (Wang and Seibert, 2024).However, the slow growth rate of diatoms in culture presents one of the main obstacles in the path of … WebJan 14, 2024 · Based on the field investigation and mesocosm experiment where diatoms were dominant, a diatom culture experiment was conducted to investigate photosynthetic performance, growth rate, and CCM... irish booksellers maine
