Microorganisms' population in culture media were determined with counting method.
These results may be related to microorganisms' population and their activity in different substrates.
Microorganisms' population in the soil was higher and when it was mixed with organic matter (palm waste and rice hull), activity of micro organisms for organic matter mineralization were increased and caused competition between plant roots and microorganisms for nutrient elements uptake.
A novel method for determination of trace amounts of microorganism populations in solution was developed by using a multiwalled carbon nanotube (MWNT) modified glassy carbon electrode and square wave voltammetry (SWV).
This study concludes that injection of ClO2 and Cl2(g) into surface water prior to rapid sand filtration is inadequate in reducing fecal indicator microorganism populations and ClO2 ineffectively kills infectious propagules of P. capsici.
This kind of assay is possible because both virulence and resistance tend to occur in approximately normal, or bell-shaped, frequency distributions; that is, most members of the host and microorganism populations occupy a central position with regard to these properties, exceptional individuals appearing at both extremes.
It is clear that NFC supply to the rumen alter the fermentation profile and therefore the ruminal microorganism populations.
Hybrid organic/inorganic RO membranes are promising in dealing with biofouling since deposited inorganics such as photocatalytic titanium dioxide (TiO2), SiO2, Zeolite A, and silver nanoparticles are excellent in reducing microorganism populations.
Figure 2(a) shows that a greater impulsive toxicant input can lead to the extinction of the two microorganisms, whereas the microorganism populations can be persistent in the smaller impulsive toxicant input environment (see Figure 2(b) and Figure 2(c)).
