Carbohydrate metabolism in the marine diatom Skeletonema costatum
Marine Biology, 1969This is a study on the metabolism of the algal biochemical constituents of a marine diatom, Skeletonema costatum. The carbohydrates, protein, and lipid, of the diatom grown under light and dark conditions were analyzed. The composition of the organic compounds did not vary in the alga grown under continuous light conditions throughout the experiment ...

Roles of carbonic anhydrase in photosynthesis of Skeletonema costatum.
Zhi wu sheng li yu fen zi sheng wu xue xue bao = Journal of plant physiology and molecular biology, 2005The role of carbonic anhydrase (CA) in photosynthesis of the marine diatom Skeletonema costatum grown at ambient level of CO(2) was investigated. Extracellular CA activity was very low. In comparison, intracellular CA activity was great part of total CA activity.

Nutrient-controlled growth of Skeletonema costatum: an applied model
Chinese Journal of Oceanology and Limnology, 2014To model Skeletonema costatum blooms and their relationship with environmental parameters in situ, a S. costatum-specific zero-dimensional box model based on the mechanistic model Eco3M was established using physiological features. The parameters were calibrated using experimental counterparts, and simulations were compared with published laboratory ...

Inhibitory effects of Skeletonema costatum on mercury methylation by Geobacter sulfurreducens PCA
Chemosphere, 2019Algae and mercury (Hg) are ubiquitous in marine environments. In this study, we investigated the effects of a typical marine algae of diatom Skeletonema costatum on Hg methylation by an iron-reducing bacterium of Geobacter sulfurreducens (G. sulfurreducens) PCA. In the absence of Skeletonema costatum, the bacterial MeHg production rate maximized at 104.

Effects of lead on growth of the marine diatom Skeletonema costatum
Marine Biology, 1979The growth rate and maximum yield of Skeletonema costatum (Grev.) Cleve in batch culture were inhibited by dissolved lead at concentrations of 0.05 to 10.0 μg Pb l-1. Growth rate, maximum yield, and respiration cell-1 decreased and photosynthesis cell-1 and cell volume increased in response to increased lead concentration in the medium.

Aquatic Toxicology, 2002
Physiological and cytological responses of the marine diatom, Skeletonema costatum, to 2,4-dichlorophenol (2,4-DCP) were investigated after exposing algal cultures to 1-6 mg x l(-1) of 2,4-DCP for 96 h. Growth rate of the diatom was significantly reduced by 2,4-DCP at and above 3.0 mg x l(-1) while other biological parameters such as photosynthetic and

The Influence of Fluctuating Light on the Growth and Photosynthesis of Skeletonema Costatum
1992The marine diatom Skeletonema costatum was grown in two light-limited continuous cultures with a 8h light:16h dark period. Although the total amount of light energy received by both cultures was the same, the way in which they received it was different. Culture 1 received one sinusoidal cycle (with the maximum 4h after the onset of light).

Effect of Skeletonema costatum (Grev.) Cleve on the growth of marine bacteria
Journal of Experimental Marine Biology and Ecology, 1979Abstract The effect of Skeletonema costatum (Grev.) Cleve on bacterial growth was investigated in mixed culture. Twenty marine bacterial strains of four genera were tested. Generally, the growth of Pseudomonas and Vibrio was inhibited by the alga. Conversely, the growth of Flavobacterium was apparently stimulated.

Cultivation of diatom skeletonema costatum in airlift photobioreactor
This work aimed to examine the performance of 3 L airlift photobioreactor system on the cultivation of Skeletonema costatum compared to that in bubble column. Firstly, the experiment was set out to determine appropriate medium for Skeletonema costatum where it became apparent that the standard F/2 medium (Guillard's medium) could only yield the best ...openaire +1 more source
Competitive interaction between Ditylum Brightwellii and Skeletonema Costatum by toxic metabolites
Netherlands Journal of Sea Research, 1989Abstract Comparative growth experiments were carried out in order to examine the role of toxic metabolites in the competition between two marine diatom species. Ditylum brightwellii and Skeletonema costatum exhibited mutual inhibition and auto-inhibition. Charcoal filtration did not entirely remove the toxicity.
