In order to check the possible effects of physico-chemical parameters on increase in biomass of metals mixture stressed fish in the natural water bodies, the research work was conducted to evaluate relationships among increase in biomass, planktonic productivity and physico-chemistry of ponds, stocked with Zn+Pb+Mn mixture stressed fish.
Oneway ANOVA and Tukey's post-hoc test were used to compare groups in softening in solvent- DC, UTS, contact angle, SFE, antibacterial activity against biofilm and against planktonic bacteria among groups at a level of 0.05 of significance.
The mixture of EIP and [H.sub.2][O.sub.2] is an effective antimicrobial agent against both planktonic bacteria and biofilms, and, as described in this subsection, some of its mechanisms of action are known.
Planktonic organisms are an interesting tool in ecotoxicology studies since they (1) are the main responsible for the transference of the pollutants from abiotic environment to biota; (2) can indicate site disturbance because they generally are the first organisms affected by pollutants; (3) have different trophic levels; and (4) recycle organic matter and pollutants concomitantly.
Other than that, the turbidity of culture was measured using UV spectrometer to evaluate the growth of the planktonic SRB.
At present, only in vitro experiments were applied against planktonic bacteria.
The disks were removed from the culture tubes, rinsed with 1x phosphate buffered saline (PBS) to remove any planktonic cells, and transferred to 1.5 mL microcentrifuge tubes containing 1 mL of PBS.
After 48 h of incubation, the planktonic growth was determined by [OD.sub.630] readings as described above.
DNA was isolated from swine wastewater, inoculum sludges, anodic biofilms (carbon felt and carbon granules), and planktonic samples of each MFC using PowerMax soil DNA isolation kit (MO BIO laboratories, Inc.).
coli O157:H7 in planktonic and biofilm state under stressed conditions of NaCl, pH, temperature and ORS (Oral Rehydration Salt) powder and then make comparisons.
Among the topics are Otto Renz (1906-92): pioneer of the Cretaceous and Paleogene stratigraphy of the Central Apennines, a history of the paleomagnetic investigations in the Umbria-Marche Apennines, whether the Rotalipora cushmani extinction at Gubbio is a planktonic foraminiferal testimonial of the onset of the Caribbean large igneous province emplacement, environmental fluctuations during the latest Cenomanian level in the Gubbio area based on an ichnofabric approach, and the Eocene Thermal Maximum 3: reading the environmental perturbations at Gubbio.
