Eighteen strains of obligately oligotrophic bacteria that grow in a medium containing 1 mg of organic carbon per liter and do not grow in a rich medium (5 g/liter of nutrient) were isolated as dominant organisms from the oligotrophic water ...
Problems in estimating growth rates of marine phytoplankton from short-term(14)C assays [0.03%]

Growth rate estimates (μ') of phytoplankton populations that were sampled from nitrogen-limited continuous cultures and then incubated for short durations in batch culture with added(14)C-HCO3 (-) were significantly different than steady-s...
Inhibition of the predatory activity ofBdellovibrio by various environmental pollutants [0.03%]
环境污染物对 Bdellovibrio 系列菌捕食活性的抑制作用

The predatory activity of bdellovibrios is affected by various environmental pollutants such as detergents, heavy metals, and pesticides. This was shown in a two-membered system ofBdellovibrio andPhotobacterium, in which the effect of the p...
Interaction ofBdellovibrio with Its prey in mixed microbial populations [0.03%]
Bdellovibrio与其猎物在混合微生物种群中的相互作用

The interaction ofBdellovibrio with its prey can be affected by the presence of other microorganisms regardless of whether they serve as a prey for the bdellovibrios. This was shown in a system in which the fate of one prey could be followe...
Barophilic growth of bacteria from intestinal tracts of deep-sea invertebrates [0.03%]
深海无脊椎动物肠道菌群的高压生长特性研究
