Kepadatan Skeletonema costatum Pada pH yang Berbeda

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.

Shifts in Diatom Dominance Associated with Seasonal Changes in an Estuarine-Mangrove Phytoplankton Community

Journal of Marine Science and Engineering, 2020
A study on seasonal phytoplankton abundance and composition in a mangrove estuary, Matang Mangrove Forest Reserve (MMFR), Malaysia, was carried out to determine the phytoplankton structure in this ecosystem, and to identify potential indicators of ...

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.

Developing and Evaluating Aquatic Passive Sampling of Environmental DNA for Microbial Community Profiling. [PDF]

Mol Ecol Resour
ABSTRACT Environmental DNA (eDNA) metabarcoding has transformed biodiversity monitoring across taxa from bacteria to mammals, yet sample collection remains a major bottleneck. Passive sampling via adsorption and entrapment has emerged as a promising alternative to overcome the limitations of conventional active filtration.

Studies on the Autoinhibitor Produced by Skeletonema costatum-II. Isolation and Identification of an Autoinhibitor Produced by Skeletonema costatum.

NIPPON SUISAN GAKKAISHI, 1992
An autoinhibitor produced by Skeletonema costatum was extracted with ethyl acetate from the cultured medium. The extract dissolved in diluted aqueous NaOH was gel-filtered on Sephadex G-15 with water. The fractions which inhibited the growth of S. costatum were extracted with ethyl acetate, and the extracts were separated by preparative thin-layer ...

Effect of the Extracts of Sargassum fusiforme on Red Tide Microalgae in East China Sea

Frontiers in Marine Science, 2021
This study examined the effects of extracts of hijiki (Sargassum fusiforme) on the growth and physiology of three species of red tide microalgae (Prorocentrum donghaiensis, Skeletonema costatum, and Heterosigma akashiwo) that commonly grow in the East ...

Chlorophyll Turnover in Skeletonema costatum, a Marine Plankton Diatom [PDF]

Plant Physiology, 1979
[(3)H]- and delta-[(14)C]Aminolevulinic acids were incorporated into the chlorophylls of Skeletonema costatum, a marine plankton diatom. In the stationary phase of growth, the tetrapyrrole-based pigments reached steady-state labeling after 10 hours. Under conditions of exponential cell division and chlorophyll accumulation, (3)H was rapidly lost from ...
