A Rhamnolipid Biosurfactant Reduces Cadmium Toxicity during Naphthalene Biodegradation
Applied and Environmental Microbiology - Tập 66 Số 10 - Trang 4585-4588 - 2000
Todd R. Sandrin, Andrea M. Chech, Raina M. Maier
ABSTRACT A model cocontaminated system was developed to determine whether a metal-complexing biosurfactant, rhamnolipid, could reduce metal toxicity to allow enhanced organic biodegradation by a Burkholderia sp. isolated from soil. Rhamnolipid eliminated cadmium toxicity when added at a 10-fo...... hiện toàn bộ
Biodegradation of Methyltert-Butyl Ether by a Pure Bacterial Culture
Applied and Environmental Microbiology - Tập 67 Số 12 - Trang 5601-5607 - 2001
Paul B. Hatzinger, Kevin McClay, Simon Vainberg, Marina Tugusheva, Charles W. Condee, Robert J. Steffan
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
Improved Template Preparation for PCR-Based Assays for Detection of Food-Borne Bacterial Pathogens
Applied and Environmental Microbiology - Tập 66 Số 10 - Trang 4539-4542 - 2000
Keith A. Lampel, Palmer A. Orlandi, Leroy Kornegay
ABSTRACT Shigella flexneri , Salmonella enterica serotype Typhimurium, and Listeria monocytogenes were applied to FTA filters, and the filters were used directly as templates to demonstrate their sensiti...... hiện toàn bộ
Direct polymerase chain reaction detection of Campylobacter jejuni and Campylobacter coli in raw milk and dairy products
Applied and Environmental Microbiology - Tập 59 Số 7 - Trang 2161-2165 - 1993
B Wegmüller, Jürg Lüthy, Urs Candrian
A polymerase chain reaction (PCR) method designed to sensitively detect and identify Campylobacter jejuni and Campylobacter coli without the need for isolating and culturing strains is described. The intergenic sequence between the flagellin genes flaA and flaB was amplified and characterized with a triple primer or seminested primer approach. A total of 50 bacterial strains, 27 of C. jeju...... hiện toàn bộ
Diversity, Dynamics, and Activity of Bacterial Communities during Production of an Artisanal Sicilian Cheese as Evaluated by 16S rRNA Analysis
Applied 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
Genetic Diversity Analysis Reveals that Geographical Environment Plays a More Important Role than Rice Cultivar in Villosiclava virens Population Selection
Applied and Environmental Microbiology - Tập 80 Số 9 - Trang 2811-2820 - 2014
Fei Wang, Shu Zhang, Mei-Gang Liu, Xian-Song Lin, Hui-Jiang Liu, You‐Liang Peng, Lin Yang, Junbin Huang, Chaoxi Luo
ABSTRACT Rice false smut caused by Villosiclava virens is an economically important disease of grains worldwide. The genetic diversity of 153 isolates from six fields located in Wuhan (WH), Yichang Wangjia (YCW), Yichang Yaohe (YCY), Huanggang (HG), ...... hiện toàn bộ
Changes in the Structure and Function of Microbial Communities in Drinking Water Treatment Bioreactors upon Addition of Phosphorus
Applied and Environmental Microbiology - Tập 76 Số 22 - Trang 7473-7481 - 2010
Xu Li, Giridhar Upadhyaya, Wangki Yuen, Jess Brown, Eberhard Morgenroth, Lutgarde Raskin
ABSTRACT Phosphorus was added as a nutrient to bench-scale and pilot-scale biologically active carbon (BAC) reactors operated for perchlorate and nitrate removal from contaminated groundwater. The two bioreactors responded similarly to phosphorus addition in terms of microbial community function (i.e., reactor performance), while drastically ...... hiện toàn bộ
Distribution of polyunsaturated Fatty acids in bacteria present in intestines of deep-sea fish and shallow-sea poikilothermic animals
Applied and Environmental Microbiology - Tập 63 Số 7 - Trang 2572-2577 - 1997
Yutaka Yano, Akihiko Nakayama, Katsuhiko Yoshida
The lipid and fatty acid compositions in nine obligate and facultative barophilic bacteria isolated from the intestinal contents of seven deep-sea fish were determined. Phospholipid compositions were simple, with phosphatidylethanolamine and phosphatidylglycerol predominating in all strains. Docosahexaenoic acid (DHA; 22:6n-3), which has not been reported in procaryotes except for deep-sea...... hiện toàn bộ
Diversity of Free-Living and Attached Bacteria in Offshore Western Mediterranean Waters as Depicted by Analysis of Genes Encoding 16S rRNA
Applied and Environmental Microbiology - Tập 65 Số 2 - Trang 514-522 - 1999
Silvia G. Acinas, Josefa Antón, Francisco Rodríguez‐Valera
ABSTRACT In a previous study (S. G. Acinas, F. Rodrı́guez-Valera, and C. Pedrós-Alió, FEMS Microbiol. Ecol. 24:27–40, 1997), community fingerprinting by 16S rDNA restriction analysis applied to Mediterranean offshore waters showed that the free-living pelagic bacterial community was very different from the bacterial cells aggregated or atta...... hiện toàn bộ
Within- and between-Lake Variability in the Composition of Bacterioplankton Communities: Investigations Using Multiple Spatial Scales
Applied and Environmental Microbiology - Tập 70 Số 1 - Trang 214-223 - 2004
Anthony C. Yannarell, Eric W. Triplett
ABSTRACT This study examined the similarity of epilimnetic bacterial community composition (BCC) across several within- and among-lake spatial scales, and the environmental factors giving rise to similar bacterial communities in different lakes were also explored. Samples were collected from 13 northern and southern Wisconsin lakes representing gradients ...... hiện toàn bộ
