Many different proteins associate with microtubules, influencing their spatial organization and function. These include proteins of a structural nature, which link microtubules to one another or to other cellular organelles and which may stimulate tubulin assembly. The second group, the so-called dynamic microtubuleassociated proteins, move subcellular components along microtubules through nucl...

Survival rate (SR) and growth rate (GR) were tested with various feed sources to identify an appropriate feed to improve the productivity in the early life stage of the rock worm Marphysa sanguinea (Montagu, 1813) (Eunicidae: Polychaeta). In addition, feed supply rates were also examined. Three experiments were performed to identify the appropriate feed for the juvenile stages of M. sanguinea. ...

The growth and development of marine fish larvae fed copepods is superior to those fed rotifers, but the underlying molecular reasons for this are unclear. In the following study we compared the effects of such diets on redox regulation pathways during development of Atlantic cod (Gadus morhua) larvae. Cod larvae were fed a control diet of copepods or the typical rotifer/Artemia diet commonly u...

Ž . Ž . Viable heterotrophic bacteria VHB -cultivated on ZoBell media and TCBS media TCBSB were enumerated from cysts that were hatched under laboratory sterile conditions as well as in a commercial hatchery without sterile conditions. Since the focus of this work was to study the TCBSB, 10 to 30 colonies growing on TCBS were isolated randomly from each sample. Results from 26 samples of differ...

The meaning of alternative biotests is described and discussed. The paper also deals with the possible application of the developmental studies of the sea Artemia franciscana nauplinus. Five-day biotests including the validation criteria are described. The possibilities of the biotests are very wide. Additionally to the standard applications in ecotoxicology, there is a possibility of modelling...

Background: Prior research on the microorganisms associated with the brine shrimp, Artemia franciscana, has mainly been limited to culture-based identification techniques or feeding studies for aquaculture. Our objective was to identify bacteria and archaea associated with Artemia adults and encysted embryos to understand the role of microbes in the Artemia life cycle and, therefore, their impo...
