Kepadatan Skeletonema costatum Pada pH yang Berbeda [PDF]

SIGANUS: Journal of Fisheries and Marine Science, 2021
ABSTRACT: The present study aimed to determine the effect of different pH level on the density of Skeletonema costatum. A completely randomized design (CRD) consisting of four treatments with 4 replications, including pH 5, pH 6, pH 7 (Control), and pH 8 was applied. Skeletonema costatum density rate and water quality were measured for data collection.

Portable Photobioreactor‐Based Stock Culture of Skeletonema costatum for Sustainable Live Feed Production in Shrimp Hatcheries of Bangladesh

Aquaculture, Fish and Fisheries
In Bangladesh's shrimp (Penaeus monodon) hatcheries, the live cells of Skeletonema costatum are used as post larvae (PL) diet for rearing. In hatcheries’ microalgae culture systems, the contamination of initial algae stock was found to be a common ...

Seasonal succession and niche differentiation in Skeletonema species driven by temperature and salinity in inner Tokyo Bay. [PDF]

J Phycol
Abstract The genus Skeletonema is a dominant diatom in coastal waters worldwide, frequently causing blooms, and it includes several cryptic species. To elucidate the occurrence patterns and niche differentiation among Skeletonema species in Tokyo Bay, Japan, sampling was conducted between June 2021 and February 2023.

High light stress under phosphorus limitation in summer may accelerate diatom shift from Skeletonema to Chaetoceros in an oligotrophic coastal area of Japan

Frontiers in Marine Science, 2023
In the Seto Inland Sea, the largest semi-enclosed sea in Japan, the most dominant diatom in the past, Skeletonema spp., has been replaced by another diatom Chaetoceros spp.

Nitrate Utilization by the Diatom Skeletonema costatum [PDF]

Plant Physiology, 1978
Nitrate uptake has been studied in nitrogen-deficient cells of the marine diatom Skeletonema 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.

Chloroplast Genomes for Five Skeletonema Species: Comparative and Phylogenetic Analysis

Frontiers in Plant Science, 2021
Skeletonema species are cosmopolitan coastal diatoms that exhibit important roles in ecological system. The chloroplast genomes (cpDNAs) have been proven to be important in the study of molecular evolution and genetic diversity.

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

, 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.
