Boron proxies in the calcium carbonate shells of planktic foraminifera are sensitive to seawater acidity, but B/Ca ratios and isotopic composition (i.e., δ11B) recorded by different foraminifer species grown under identical environmental conditions differ significantly systematically. Specifically, Globigerinoides ruber displays higher δ11B than Trilobatus sacculifer Orbulina universa. It has b...

A contaminação pelo novo coronavírus tem provocado reflexões e questionamentos sobre as transformações que a cidade vem passando durante esse período. E sabendo áreas verdes são importantes para vida da população reside nos centros urbanos, o estudo teve como objetivo verificar através de uma entrevista período pandemia COVID-19 os frequentadores percebem utilizam parques além com administrador...

In order to develop a practical method for the decomposition of intact chicken feathers, a moderate thermophile strain, Meiothermus ruber H328, having strong keratinolytic activity, was used in a bio-type garbage-treatment machine working with an acidulocomposting process. The addition of strain H328 cells (15 g) combined with acidulocomposting in the garbage machine resulted in 70% degradation...

Many camphor-degrading bacteria that are able to transform 2-methylisoborneol (2-MIB) have been identified. Three of these strains have been examined in detail. Rhodococcus ruber T1 metabolizes camphor through 6-hydroxycamphor but converts 2-MIB to 3-hydroxy-2-MIB. Pseudomonas putida G1, which metabolizes camphor through 5-hydroxycamphor, converts MIB primarily to 6-hydroxy-2-MIB. Rhodococcus w...

The Oligocene rodent assemblage from Gözükızıllı (Anatolia, Turkey) is described. relatively small, but it contains the new large and hypsodont baluchimyine Daxneria fragilis nov. gen. sp. In addition, ctenodactyline Sayimys, two species of Eucricetodon: E. ruber oculatus are present. Rare glirids Bransatoglis Peridyromys/Microdyromys a dipodid that could not be classified. Asian some European ...

Seventeen pink-pigmented strains of the genus Thermus were isolated from samples collected from thermal areas of Iceland. The strains were examined by using phenotypic characterization and DNA:DNA homology and were compared with recognized strains. Visually, the strains could be divided into three groups based on their pigmentation; however, spectroscopic studies of the pigments indicated littl...
