Mercury-induced genotoxicity in marine diatom (Chaetoceros tenuissimus)

Environmental Science and Pollution Research, 2015
In this paper, we present an evaluation of genotoxic responses in marine diatom, Chaetoceros tenuissimus, isolated from Kandla Creek (lat 23.03° N, long 70.22° E), Gujarat, India, in terms of impairment of DNA integrity as a function of their exposure to elevated levels of mercury (Hg) under laboratory conditions. DNA integrity in C.

Enhanced productivity of Chaetoceros calcitrans in airlift photobioreactors

Bioresource Technology, 2007
The various modes of cultivation of Chaetoceros calcitrans in airlift photobioreactors (ALPBRs) were examined. The batch system illustrated that the airlift configuration was superior to the bubble column as the airlift supported the circulation of the cell within the system, leading to a better light utilization.

Automatic setae segmentation from Chaetoceros microscopic images

Microscopy Research and Technique, 2014
ABSTRACTA novel image processing model Grayscale Surface Direction Angle Model (GSDAM) is presented and the algorithm based on GSDAM is developed to segment setae from Chaetoceros microscopic images. The proposed model combines the setae characteristics of the microscopic images with the spatial analysis of image grayscale surface to detect and segment

Unsupervised pixel-wise classification for Chaetoceros image segmentation

Neurocomputing, 2018
Abstract Chaetoceros is a dominant genus of marine planktonic diatoms with worldwide distribution. Due to the difficulty of extracting setae from Chaetoceros images, automatic segmentation of Chaetoceros is still a challenging task. In this paper, we address this difficult task by regarding the whole segmentation process as unsupervised pixel-wise ...

Comparative analysis of mitochondrial genomes of Chaetoceros species

Journal of Phycology
AbstractChaetoceros is one of the most diverse genera of marine planktonic diatoms. Chaetoceros species are common and may become dominant in coastal ecosystems. Many Chaetoceros species can develop harmful algal blooms with negative effects on the aquaculture industry.
