Temporal variability of attached and free-living bacteria in coastal waters [0.03%]
附生和自由生活的细菌在近海海域的时空变化性
M Unanue,B Ayo,I Azúa et al.
M Unanue et al.
The temporal variability of the abundance and the incorporation of (3)H-thymidine and (14)C-glucose by attached and free-living bacteria, as well as their relation with environmental factors, were analyzed in a coastal marine ecosystem duri...
The occurrence of chemolitho-autotrophic nitrifiers in water-saturated grassland soils [0.03%]
水饱和草甸土壤中化能自养型硝化细菌的出现
G J Both,S Gerards,H J Laanbroek
G J Both
Relatively high most probable number (MPN) counts of chemolithotrophic nitrite oxidizers were present in water-saturated soils compared with MPNs and activity of ammonia oxidizers. These high numbers of nitrite oxidizers were confirmed by f...
Assimilation of CO2 and introduced organic compounds by bacterial communities in groundwater from southeastern Sweden deep crystalline bedrock [0.03%]
瑞典东南部深部结晶岩地下水细菌群落对二氧化碳和外来有机物的同化作用

S J Michereff et al.
Curvularia eragrostidis yam leaf spot is a serious concern among the northeast Brazilian yam growing areas. In order to study its biocontrol, bacterial isolates from the yam phylloplane were tested against the pathogen. They were evaluated ...
Density, activity, and diversity of bacteria indigenous to a karstic aquifer [0.03%]
喀斯特含水层土著细菌的密度、活性和多样性
K J Rusterholtz,L M Mallory
K J Rusterholtz
The microbial ecology of karstic ground water is largely unknown. The density, activity, and diversity of bacteria indigenous to subsurface karstic material in Mammoth Cave National Park, Mammoth Cave, Kentucky were studied using minimally ...
Biodegradation of phenolic compounds by sulfate-reducing bacteria from contaminated sediments [0.03%]
受污染沉积物中硫酸盐还原菌对苯酚类化合物的生物降解作用研究
S L Mort,D Dean-Ross
S L Mort
The biodegradation of phenolic compounds under sulfate-reducing conditions was studied in sediments from northern Indiana. Phenol, p-cresol and 4-chlorophenol were selected as test substrates and added to sediment suspensions from four site...
Degradation by and toxicity to bacteria of chlorinated phenols and benzenes, and hexachlorocyclohexane isomers [0.03%]
氯化酚和苯以及六氯环己烷异构体的降解性和毒性研究细菌
E Lang,H Viedt
E Lang
Mixed cultures degrading chlorinated benzenes, chlorinated phenols, or hexachlorocyclohexane (HCH) as the sole source of carbon and energy were obtained by enrichment from contaminated soil samples. Cultures which metabolized 3-chlorophenol...
Phagotrophy of fluorescently labeled bacteria by an oceanic phytoplankter [0.03%]

M D Keller et al.
Using fluorescently-labeled bacteria and detection by flow cytometry and epifluorescence microscopy, we demonstrate inducible mixotrophy in a marine photosynthetic flagellate, Ochromonas sp. (class Chrysophyceae). Phagotrophic uptake of bac...
Heterotrophic microbial activity in shallow aquifer sediments of Long Island, New York [0.03%]
纽约长岛浅层含水层沉积物中异养微生物活性
J Kazumi,D G Capone
