Two strains of sulfate-reducing bacteria of the genus Desulfovibrio (A2 and TomC) isolated from metal mining waste were able to grow on agar Postgate C nutrient medium under microaerobic conditions. Since their growth in liquid nutrient medium was just slightly affected by 1% O 2 (initial ...
Whole vertebrate blood is a colloidal suspension of predominantly red blood cells (erythrocytes) in plasma. Whole blood also consists primarily of protein by dry weight, with only small amounts of lipid, carbohydrate and trace elements [19]. However, hematological parameters also vary among vertebrat...
Beneficial microorganisms are used to stimulate the germination of seeds; however, their growth-promoting mechanisms remain largely unexplored.Bacillus subtilisis commonly found in association with different plant organs, providing protection against pathogens or stimulating plant growth. We report that applica...

The numbers of inhalable bacteria were quantified after 3 and 7 days of incubation on 100 % Nutrient agar (Oxoid, Basingstoke, UK) with actidione (cycloheximide; 50 mg/l (Serva, Germany)) at 25 °C. The exposure to fungi and bacteria are expressed as TWA in colony forming units (cfu) ...
of fungal hyphae can be produced. This must mean that the diffusion distances ofthe enzymes degrading the wood are very short. We have demonstrated that the white-rot fungusS. pulverulentum grows 1 mm per hour on a malt agar plate surface and 0.5 mm an hour in eitherbirch- or spruce-...
Pieces of agar gel (a polymer containing both carboxylated and sulfated groups) that were stained using the same method as for colonies showed a strong blue colour at both pH values, indicating that the seawater medium did not affect the staining reaction. Also, Crayton (1982)found that ...
The AmrZ/FleQ hub has been identified as a central node in the regulation of environmental adaption in the plant growth-promoting rhizobacterium and model for rhizosphere colonization Pseudomonas ogarae F113. AmrZ is involved in the regulation of motilit
The numbers of fungi culti- vable on dichloran glycerol agar (DG 18 agar; Oxoid, Basingstoke, UK) at 25 and 45°C were measured. Quantifications were made of the number of bacteria cultivable at 25°C on Nutrient agar (Oxoid) with cycloheximide (50 mg lÀ1) and o...
campestris was grown in Nutrient Agar (NA) at 25 °C for 72 h. The bacterial cells were scraped from the NA plates, suspended in sterilized distilled water and the concentration adjusted to 5 × 106 colony forming units mL−1 from optical density measurements (OD600 nm absorbance ...
