The purpose of this study was to investigate the reproductive phenology and sharing of floral resource (nectar) of Dahlstedtia pinnata (Benth.) Malme. (Fabaceae), endemic of Atlantic forest, among hummingbirds. For the phenology, we looked at the presence of reproductive structures in the plants, and for floral resource sharing, the frequency of potential pollinators and foraging behaviors were...
[1] A down-core comparison of two commonly applied foraminiferal cleaning procedures for Mg/Ca paleothermometry has been conducted using well-preserved Globigerinoides ruber white (250–300 mm) from core material deposited under varying terrigenous-input and bottom water conditions. This study demonstrates that in the majority of investigated core materials, both cleaning methods yield fairly co...
A Gram-stain-negative, cream-pigmented, motile, extremely halophilic archaeon, designated strain IC38(T), was isolated from a saline mud sample taken from a hypersaline lake, Aran-Bidgol, in Iran. The strain required at least 2.5 M NaCl for growth. However, MgCl2 was not required. Optimal growth occurred with 4.3 M NaCl and 0.2 M MgCl2. The optimum pH and temperature for growth were pH 7.0 and ...
A novel, extremely thermophilic bacterium, designated strain 17S(T), was isolated from a deep-sea hydrothermal vent chimney at the Suiyo Seamount in the Izu-Bonin Arc, Japan. The cells were rods with no apparent motility, most of which were narrow in the middle in the exponential-growth phase and had several polar flagella at both ends. Growth was observed between 45 and 80 degrees C (optimum t...
Previous studies analyzing 2,200 plant extracts indicated anti-enterococcal activity in 25 extracts obtained from Brazilian forests' plants. In the present study, these extracts were subjected to microdilution broth assay (MDBA) and disk diffusion assay (DDA) using planktonic Enterococcus faecalis ATCC(®) 29212™ and were submitted to phytochemical analysis in TLC and HPLC. Three extracts obtain...
The waste chicken feathers were treated with the enzymes (dissociating disulfide bonds) produced by thermophilic Meiothermus ruber H328, and then milled subjected to hot-press compression molding. It was found that recrystallization of feather keratin interfered some extent due lack S-S bonds. On other hand, slight reinforcement resin wood fibers effective enhance tensile behavior thermal stabi...
