Screening for microbiological contaminants is performed via a cultured enrichment, followed by enumeration using optical laser readings to measure biological load. ProVerde microbiological package 1 (MB1) screens for three categories of bacteria including total aerobic count (AC), total coliform (CC), total enterobacteriacea (EB), and a total yeast and mold (YM) test using BioMerieux TEMPO as the current process of record.Â
