The response of natural populations of bacteria (prepared by passing Lake Kinneret water through 1 μm filters) to additions of Fe(2+) and/or the chelator ethylenediaminetetraacetic acid (EDTA) was followed by measuring the incorporation of...
Biogeochemistry of oxalate in the antarctic cryptoendolithic lichen-dominated community [0.03%]
南极隐藻类地衣群落中草酸的生物地球化学特性

Cryptoendolithic (hidden in rock) lichen-dominated microbial communities from the Ross Desert of Antarctica were shown to produce oxalate (oxalic acid). Oxalate increased mineral dissolution, which provides nutrients, creates characteristic...
Decomposition of (14)C-labeled cellulose substrates in litter and soil from a beechwood on limestone [0.03%]

The decomposition of three different (14)C-labeled cellulose substrates (plant holocellulose, plant cellulose prepared from (14)C-labeled beech wood (Fagus sylvatica) and bacterial cellulose produced by Acetobacter xylinum) in samples from ...
Selecting inocula for the biodegradation of organic compounds at low concentrations [0.03%]
低浓度下促进有机物降解菌种的选择

M A Pahm
The inability of many organisms to degrade pollutants at low concentrations is a problem when selecting inocula for bioremediation of sites with these low concentrations. Thus, a study was conducted to determine the effect of low concentrat...
Effect of dispersed oil on heterotrophic bacterial communities in cold marine waters [0.03%]
分散的石油对冷海水异养细菌群落的影响

Mesocosm studies were conducted to evaluate the effect of dispersed oil on total and heterotrophic bacterial communities of under-ice seawater from the St. Lawrence Estuary. A regular survey of bacterial changes in the oil-contaminated seaw...
Benthic flagellates and ciliates in fine freshwater sediments: Calibration of a live counting procedure and estimation of their abundances [0.03%]
淡水细质沉積物中底栖鞭毛虫和纤毛虫的种类鉴定及丰度估算——一种活体计数方法的建立及应用校正

Despite the recognized importance of protozoans (flagellates and ciliates) as predators of bacteria, there are very few estimates of their abundance in fine sediments of freshwater lakes. This is due, in part, to the lack of a standard meth...
Immunofluorescence detection of the denitrifying strain Pseudomonas stutzeri (ATCC 14405) in seawater and intertidal sediment environments [0.03%]
海水及潮间带底质中反硝化菌恶臭假单胞菌（ATCC14405）的免疫荧光检测技术研究

B B Ward
A strain-specific immunofluorescence assay for enumeration of a marine denitrifying bacterium was developed and applied in the marine environment. The polyclonal antiserum for Pseudomonas stutzeri (ATCC 14405) did not react with other pseud...
The presence, nature, and role of gut microflora in aquatic invertebrates: A synthesis [0.03%]
