Monitoring Biolog patterns and &lt;i&gt;r/K&lt;/i&gt;-strategists in the intensive culture of &lt;i&gt;Artemia&lt;/i&gt; juveniles
Provedor de dados: 27
Autores: Verschuere, L.; Dhont, J.; Sorgeloos, P.; Verstraete, W.
&lt;i&gt;Artemia&lt;/i&gt; juveniles were cultured under intensive conditions in three series of six tanks at different times. Both plate counts and Biolog GN microtitre plates were used to monitor the microbial community. Repetitions of the &lt;i&gt;Artemia&lt;/i&gt; cultures in time revealed significant differences in Biolog patterns and bacterial counts, showing that normal culture practices, including chlorination of the sea water, does not allow control of the associated microbial community. However, the similarity among the Biolog fingerprints of all 18 tanks as determined by the Pearson correlation coefficient was always high. Both observations together indicate that the microbial community which colonizes the culture tanks seems to be determined by...

Selection of bacteria enhancing the growth rate of axenically hatched rotifers (&lt;i&gt;Brachionus plicatilis&lt;/i&gt;)

The effect of bacterial strains on the growth rate of rotifers, Brachionus plicatilis, was determined under monoxenic conditions. The first objective was to obtain sterile rotifer cultures starting from rotifer resting eggs using merthiolate or glutaraldehyde as disinfectant. Sterile rotifer cultures were obtained, without affecting the hatching ability of the resting eggs, when 0.05 µl/l glutaraldehyde was used. This disinfection procedure was used to examine the effect of 20 bacterial strains, isolated from well-performing live-feed production systems, on the population growth rate of rotifers cultured under monoxenic conditions. Five out of the 20 bacterial strains tested were able to improve significantly the asexual reproduction of rotifers. The...

Microbial control of the culture of &lt;i&gt;Artemia&lt;/i&gt; juveniles through preemptive colonization by selected bacterial strains
Provedor de dados: 27
Autores: Verschuere, L.; Rombaut, G.; Huys, G.; Dhont, J.; Sorgeloos, P.; Verstraete, W.
The use of juvenile &lt;i&gt;Artemia&lt;/i&gt; as feed in aquaculture and in the pet shop industry has been getting more attention during the last decade. In this study, the use of selected bacterial strains to improve the nutritional value of dry food for &lt;i&gt;Artemia&lt;/i&gt; juveniles and to obtain control of the associated microbial community was examined. Nine bacterial strains were selected based on their positive effects on survival and/or growth of &lt;i&gt;Artemia&lt;/i&gt; juveniles under monoxenic culture conditions, while other strains caused no significant effect, significantly lower rates of survival and/or growth, or even total mortality of the &lt;i&gt;Artemia&lt;/i&gt; . The nine selected strains were used to preemptively colonize the...

Selected bacterial strains protect &lt;i&gt;Artemia&lt;/i&gt; spp. from the pathogenic effects of &lt;i&gt;Vibrio proteolyticus&lt;/i&gt; CW8T2
Provedor de dados: 27
Autores: Verschuere, L.; Heang, H.; Criel, G.R.J.; Sorgeloos, P.; Verstraete, W.
In this study &lt;i&gt;Vibrio proteolyticus&lt;/i&gt; CW8T2 has been identified as a virulent pathogen for &lt;i&gt;Artemia&lt;/i&gt; spp. Its infection route has been visualized with transmission electron microscopy. The pathogen affected microvilli and gut epithelial cells, disrupted epithelial cell junctions, and reached the body cavity, where it devastated cells and tissues. In vivo antagonism tests showed that pre-emptive colonization of the culture water with nine selected bacterial strains protected &lt;i&gt;Artemia&lt;/i&gt; juveniles against the pathogenic effects. Two categories of the selected strains could be distinguished: (i) strains providing total protection, as no mortality occurred 2 days after the experimental infection with &lt;i&gt;V....
