Transcriptomic and physiological responses of Skeletonema costatum to ATP utilization

open access: yesEnvironmental Microbiology, 2020
Summary The capacity of phytoplankton to utilize dissolved organic phosphorus (DOP) plays an important role in their competition for resources when the availability of dissolved inorganic phosphorus (DIP) is low in the aquatic systems.

Physiological observations on a diatom Skeletonema costatum (Greville) Cleve [PDF]

open access: yes, 1998
A chain-forming diatom Skeletonema costatum (Greville) Cleve collected from Yatsushiro Sea, Japan was cultured to determine the optimum level of some physico-chemical factors for their growth under laboratory conditions. Filtered and sterilized aged sea water enriched by adding nutrient solution (Provasoli 1968) was used as the culture medium.

UBIQUITIN INSKELETONEMA COSTATUM

Diatom Research, 1995
Western blotting experiments performed with an anti-ubiquitin antibody showed that Skeletonema costatum cells contained free ubiquitin and high molecular weight ubiquitin conjugates. An estimate of free ubiquitin and ubiquitin conjugates by a solid phase immunoassay (Haas & Bright 1985) provided values of 0.31 ± 0.04 pmol/107 cells for free ubiquitin ...

Production of Octadienal in the Marine Diatom Skeletonema costatum

Organic Letters, 2003
[reaction: see text] Marine diatoms produce alpha,beta,gamma,delta-unsaturated aldehydes that have detrimental effects on the reproduction of their natural predators. The production of these defensive metabolites is suggested to involve enzymatic oxidation of polyunsaturated fatty acids. In this paper, feeding experiments with labeled precursor provide

Effects of hypoxia on growth of the diatom Skeletonema costatum

Journal of Experimental Marine Biology and Ecology, 2012
Abstract Hypoxia, defined as dissolved oxygen falls below 2.8 mg O 2 L − 1 , affects several 100,000 km 2 of marine water worldwide. Previous studies have shown that hypoxia results in aberrant behaviors of benthic fauna, collapse of fisheries, and major changes in the structure and trophodynamics of marine ecosystems. Nevertheless, it is not known

Impact of silver nanoparticles on marine diatom Skeletonema costatum

Journal of Applied Toxicology, 2016
AbstractWhen silver nanoparticles (AgNPs) are used commercially at a large scale, they infiltrate the environment at a rapid pace. However, the impact of large quantities of AgNPs on aquatic ecosystems is still largely unknown. In aquatic ecosystems, the phytoplanktons have a vital ecological function and, therefore, the potential impact of AgNPs on ...
