Taxonomic Groups of Airborne Bacteria (a Summary)

A monitor for airborne bacteria.

A unique agar drum sampler is described which indicates, continuously, the number of viable, bacterial particles per unit volume of air at the time and point of sampling. By selection of the timer and the sampling rate the sampler is suitable for quite a wide range of concentration and time. An impaction line of 484 in. greatly increases the capacity of this device over slit samplers and other ...

Responses of Aquatic Bacteria to Terrestrial Runoff: Effects on Community Structure and Key Taxonomic Groups

Organic fertilizer application is often touted as an economical and effective method to increase soil fertility. However, this amendment may increase dissolved organic carbon (DOC) runoff into downstream aquatic ecosystems and may consequently alter aquatic microbial community. We focused on understanding the effects of DOC runoff from soils amended with compost, vermicompost, or biochar on the...

Correlation of taxonomic criteria for a collection of marine bacteria.

Numerical taxonomy was done on 208 strains of marine bacteria. The collection was segregated into eight groups, seven of which contained Vibrio sp. Nucleic acid base ratio studies on a typical Vibrio sp. from each group and other genera were done. The phenotypically different Vibrio sp. had a narrow range of base ratios. The other genera had base ratios more similar to the base ratios reported ...

A Numerical Taxonomic Study of Some Pseudomonas-like Marine Bacteria

The abilities of 26 marine and 12 other Pseudomonas-like strains of bacteria to grow on single carbon sources, their antibiotic sensitivities and complement of some enzymes of intermediary metabolism were numerically analysed and gave five phenons. Two phenons contained strains with more than 55 mol % GC and were regarded as Pseudomonas spp., two were similar to the genus AZteromonas, and one w...
