For two strains, the green alga Pleurococcus CVB4 and the cyanobacterium Lyngbya CCB2, isolated from the pioneering algal biocoenosis present on a marble statue, we determined the optimum range of growth in selective cultural media in relat...
Effect of sampling scale on the assessment of epiphytic bacterial populations [0.03%]

Bacterial populations on above-ground plant surfaces were estimated at three different biological scales, including leaflet disks, entire leaflets, and whole plants. The influence of sample scale on the estimation of mean bacterial populati...
Inter-root movement of Azospirillum brasilense and subsequent root colonization of crop and weed seedlings growing in soil [0.03%]
巴西固氮螺菌的根际转移及其对土壤中农作物和杂草幼苗根系的定殖

Inter-root movement and dispersion of the beneficial bacterium Azospirillum brasilense were monitored in root systems of wheat seedlings growing in the field and in growth chamber soil trays. Two strains were used, a motile wild-type strain...
Maximum growth temperature ranges of Aeromonas Spp. isolated from clinical or environmental sources [0.03%]

Only a limited number of phenotypic tests are available for the differentiation of all 13 known hybridization groups (HG) of Aeromonas spp. These organisms have a wide spectrum of warm-blooded and cold-blooded hosts. In the present study, t...
The relative abundance and seawater requirements of gram-positive bacteria in near-shore tropical marine samples [0.03%]
近岸热带海洋样品中革兰氏阳性菌的相对丰度及其海水需求量

The relative abundance of gram-positive bacteria in a variety of near-shore marine samples was determined using the KOH method. Gram-positive bacteria accounted for 14%, 25%, 31 %, and 12%, respectively, of the colony-forming bacteria obtai...
Attached and free-living bacteria: Production and polymer hydrolysis during a diatom bloom [0.03%]
附生和自由生活的细菌在硅藻群落动态中的作用：聚合物水解与胞外聚合物产生的关系研究

M Middelboe et al.
Abundance, production and extracellular enzymatic activity of free-living and attached bacteria were measured during the development and collapse of a spring bloom in a eutrophic lake. Free-living bacteria accounted for most of the total ba...
Nutrient enrichment and nutrient regeneration stimulate bacterioplankton growth [0.03%]
营养增丰和营养再生可刺激细菌浮游生物的生长

T H Chrzanowski
Bacterial abundance results from predatory losses of individuals and replacement of losses through growth. Growth depends on sustained input of organic substrates and mineral nutrients. In this work we tested the hypothesis that bacterial g...
