Hot Spring Metagenomics
Hot springs have been investigated since the XIX century, but isolation and examination of their thermophilic microbial inhabitants did not start until the 1950s. Many thermophilic microorganisms and their viruses have since been discovered, although the real complexity of thermal communities was envisaged when research based on PCR amplification of the 16S rRNA genes arose. Thereafter, the pos...

متن کاملOccurrence of Bact. Alcaligenes Sp. in Duck Eggs
room temperature. In plain broth there was surface growth, indicated by a whitish ring in contact with the glass, and a viscid sediment, partially disintegrating on shaking. In gelatine stab, growth occurred without liquefaction. Fermentation and biochemical reactions were as follows : No change in glucose, maltose, lactose, sucrose, mannitol or salicin. M.R. and V.P. reactions negative; no red...
متن کاملArtificial incubation of Muscovy duck eggs: why some eggs hatch and others do not.
This study was designed to gain insight into the influence of spraying and cooling, during artificial incubation, on the embryo metabolic rate and hatching ability of Muscovy duck eggs. Three times a week 93 incubated eggs were sprayed and cooled for 0.5 h at room temperature. Daily embryo metabolic rate was measured in 30 eggs with a water vapor conductance ranging from 1.15 to 2.07 mg/day-kPa...
متن کاملIncidence of salmonellae in duck eggs in Thailand.
Detection of salmonellae was performed on egg shells and egg contents of duck eggs. Five hundred and sixty-four tested samples were came from 1,128 eggs, 2 eggs in each sample. Eggs were collected from retail markets in Bangkok, Chon Buri, Chachoengsao, Lop Buri, Ang Thong and Nakhon Ratchasima provinces during January through June 1992. The percentage of salmonellae contamination on the egg sh...
