Fertility Element Storage in Chaparral Vegetation, Leaf Litter, and Soil1
2 Assoc. Prof. of Forestry, University of California, Berkeley. Abstract: This study was conducted on various chaparral sites sampled throughout California in the range of the following species: chamise, Adenostoma fasiculatum; scruboak, Quercus dumosa; and Ceanothus cuneatus, & C. crassifolius. Data for elemental composition, total vegetation and leaf litter weights, and elemental storage weig...
متن کاملMicroorganism Tracking Microscope System
Continuous observation of individual motile microorganisms is difficult, since their swimming speed is fast compared with their diameters. In fact, some bacteria can swim as fast as 50 diameters/s [1]. At this speed, microorganisms can quickly go out of the range of static measurement instruments, such as the field of view of optical microscopes. This problem can be solved by tracking the micro...
متن کاملUltraviolet Radiation for Microorganism Inactivation in Wastewater
The purpose of this research stream is to evaluate the kinetics of bacterial strains of Pseudomonas aeruginosa, to establish the influence of UV doses on the kinetics of disinfection, to study UV-resistant strains of Pseudomonas aeruginosa, and to underline the influence of suspended solids on the inactivation kinetics of these strains. Furthermore, and due to the lack of readily available info...
متن کامل[Metagenomics in studying gastrointestinal tract microorganism].
Animal gastrointestinal tract contains a complex community of microbes, whose composition ultimately reflects the co-evolution of microorganisms with their animal host. The gut microbial community of humans and animals has received significant attention from researchers because of its association with health and disease. The application of metagenomics technology enables researchers to study no...
متن کاملStreptomycin resistance in a streptomycin-producing microorganism.
Cell-free extracts of Streptomyces bikiniensis contain an adenosine 5'-triphosphate-dependent kinase which inactivates streptomycin (Sm) and dihydrostreptomycin by phosphorylation. The products have been identified as streptomycin 6-phosphate and dihydrostreptomycin 6-phosphate. Activity was not present in logarithmic-phase cells, which were susceptible to 25 mug of Sm per ml. In stationary-pha...
