Monitoring precursor 16S rRNAs of Acinetobacter spp. in activated sludge waste-water treatment systems

Article Abstract:

Precursor 16S rRNAs of Acinetobacter spp. in activated sludge waste-water treatment systems have been monitored and it appears they undergo a change in growth activity in wastewater treatment systems. Acinetobacter calcoaceticus grown in LB medium had a more substantial and faster increase in precursor 16S rRNA levels vs the increase in total 16S rRNA levels in exponential growth. Precursor 16S rRNa levels of Acinetobacter spp. increased transiently when activated sludge was mixed with influent wastewater in full- and lab-scale wastewater treatment systems.

Monitoring precursor 16S rRNAs of Acinetobacter spp. in activated sludge wastewater treatment systems

Article Abstract:

Research has been conducted on the Escherichia coli precursor 16S rRNA. The oligonucleotide probes that target the 3' region of the Acinetobacter precursor 16S rRNA have been designed.

Are readily culturable bacteria in coastal North Sea waters suppressed by selective grazing mortality?

Article Abstract:

Research has been conducted on culturable bacterial lineages from the coastal North Sea picoplankton. The growth of these leneages has been studied under various incubation conditions, and the results suggest that bacteria affiliated with frequently isolated genera such as Vibrio and Alteromonas are rare in this picoplankton due to the counterballance between their rapid growth response to changing environmental conditions and higher grazing mortality.
