Physiological responses to light regime of a Mediterranean lagoon strain of Chaetoceros tenuissimus and a collection strain of Chaetoceros calcitrans [PDF]

Journal of Applied Phycology
Abstract Diatoms play a fundamental ecological role as primary producers in aquatic food webs. Among these, a little number of solitary species of the genus Chaetoceros are of great interest as live food for aquaculture, including major taxa like Chaetoceros calcitrans which have been well studied in terms of growth and essential lipid ...

Semicontinuous cultures of Four microalgae with a nonconventional medium

Ciencias Marinas, 1993
Four microalgae, Chaetoceros sp., Phaeodactylum tricomutum Bohlin, Tetraselmis sp. and Pavlova lutheri (Droop) Hibberd, were kept in semicontinuous cultures at dilution rates between 75 and 15%, depending on species and medium.

Developing and Evaluating Aquatic Passive Sampling of Environmental DNA for Microbial Community Profiling

Molecular Ecology Resources, Volume 26, Issue 3, April 2026.
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.

Antibacterial activity in three Chaetoceros microalgae species cultures by using antibiotics

, 2021
- Diatoms, such as Chaetoceros, grow in a mutualistic relationship with bacteria. However, in some cases, it is necessary to grow them in bacteria-free cultures. To reduce bacterial load, antibiotics are used, and on certain occasions it is necessary to
