Various pretreatments of metaphase spreads were examined to obtain optimal DNA labelling patterns while maintaining chromosome integrity during in situ hybridization procedures. Preparations of African green monkey (AGM) chromosomes fixed in methanol-acetic acid (CV-1 cell line) were treated by coating

This study sought to characterize bacterial and archaeal populations in a perchloroethene- and butyrate-fed enrichment culture containing hydrogen-consuming "Dehalococcoides ethenogenes" strain 195 and a Methanospirillum hungatei strain. Phylogenetic characterization of this microbial community was done via 16S rRNA gene clone
