According to International Standard Organization (ISO 14698 1) [ 23] microbial standard procedures, air contamination was evaluated by active sampling (SAS, Aquaria Microflow, Milan, Italy) with a flow rate of 180 L/min.
Microbial activities were not correlated with the exchangeable fraction of heavy metals, indicating that microbial function is not strongly affected by these metals, likely due to the efficiency of the reclamation procedure to reduce metals toxicity.
The costs of chemical confirmation can be considerably reduced by introducing a preliminary microbial identification procedure.
This method consists of seven test plates and is used by the USDA-FSIS as a microbial confirmatory procedure for samples which tested positive in initial screening tests such as STOP [ 27], CAST [ 28], and FAST [ 29].
However, due to the relatively low concentration of P compounds present in environmental compartments (soils and sediments), natural organic matter (NOM), and microbial biomass, the procedures for sample preparation for the detection of P content by NMR require a careful setup of experimental conditions, including the removal of paramagnetic species [25,27,11].
Yet, microbial groundwater sampling procedures have rarely been evaluated in IFREs.
DNA yield is affected by extraction procedure, microbial diversity merely.
After this procedure, microbial cells (1.0 × 10 cells/mL for yeasts and 1.0 × 10 cells/mL for bacteria) were added to the wells and the plates were incubated at 36°C for 72 h [ 22].
Several studies have assessed the efficiency of various antigen loading procedures, including microbial vectors.
Additional microbial invasion and dental procedures are subsequent events that lead to the progression of osteonecrosis [31].
