ABSTRACTBiodegradation of methyltert-butyl ether (MTBE) by the hydrogen-oxidizing bacteriumHydrogenophaga flavaENV735 was evaluated. ENV735 grew slowly on MTBE ortert-butyl alcohol (TBA) as sole sources of carbon and energy, but growth on these substrates was greatly enhanced by the ad...... hiện toàn bộ
Diversity, Dynamics, and Activity of Bacterial Communities during Production of an Artisanal Sicilian Cheese as Evaluated by 16S rRNA AnalysisApplied and Environmental Microbiology - Tập 68 Số 4 - Trang 1882-1892 - 2002
Cinzia Lucia Randazzo, Sandra Torriani, A.D.L. Akkermans, Willem M. de Vos, Elaine Vaughan
ABSTRACT
The diversity and dynamics of the microbial communities during the manufacturing of Ragusano cheese, an artisanal cheese produced in Sicily (Italy), were investigated by a combination of classical and culture-independent approaches. The latter included PCR, reverse transcriptase-PCR (RT-PCR), and denaturing gradient gel electrophores...... hiện toàn bộ
Dead-End Hollow-Fiber Ultrafiltration for Recovery of Diverse Microbes from WaterApplied and Environmental Microbiology - Tập 75 Số 16 - Trang 5284-5289 - 2009
Carmela M. Smith, Vincent R. Hill
ABSTRACT
Dead-end ultrafiltration (DEUF) is an alternative approach to tangential-flow hollow-fiber ultrafiltration that can be readily employed under field conditions to recover microbes from water. The hydraulics of DEUF and microbe recovery for a new DEUF method were investigated using 100-liter tap water samples. Pressure, flow rate, and ...... hiện toàn bộ
Autotransporter-Based Antigen Display in Bacterial GhostsApplied and Environmental Microbiology - Tập 81 Số 2 - Trang 726-735 - 2015

ABSTRACT
Bacterial ghosts are empty cell envelopes of Gram-negative bacteria that can be used as vehicles for antigen delivery. Ghosts are generated by releasing the bacterial cytoplasmic contents through a channel in the cell envelope that is created by the controlled production of the bacteriophage ϕX174 lysis protein E. While ghosts posses...... hiện toàn bộ

Fatty Acid methyl ester profiles for characterization of glomalean fungi and their endomycorrhizaeApplied and Environmental Microbiology - Tập 61 Số 1 - Trang 58-64 - 1995
J. H. Graham, N. C. Hodge, Joseph B. Morton
Arbuscule-forming fungi in the order Glomales form obligate endomycorrhizal associations with plants that make them difficult to quantify, and taxonomy of the group is only beginning to be objectively understood. Fatty acid methyl ester (FAME) profiles were analyzed to assess the diversity and quantity of fatty acids in 53 isolates of 24 glomalean species. Spores and endomycorrhizal roots ...... hiện toàn bộ
Production and pH-Dependent Bactericidal Activity of Lactocin S, a Lantibiotic from Lactobacillus sake L45Applied and Environmental Microbiology - Tập 61 Số 1 - Trang 175-179 - 1995
C I Mortvedt-Abildgaa, Jon Nissen‐Meyer, Birthe Jelle, Benedikte Grenov, Morten Skaugen, Ingolf F. Nes
The amount of lactocin S activity in a growing culture depends on the growth stage of the bacteria, the pH of the medium, the presence of ethanol, and the aeration of the culture. We observed the highest levels of bacteriocin activity in the early stationary growth phase of cultures at 30 deg C. When Lactobacillus sake L45 was grown in a fermentor at pH 5, it produced 2,000 to 3,000 bacter...... hiện toàn bộ
