The northernmost Harbin strain (N strain) of the Asian corn borer, Ostrinia furnacalis enters facultative diapause as fully grown larvae in response to short daylengths; whereas the southernmost Ledong strain (S strain) exhibits almost no diapause under the same light conditions. In the present study, we examined the inheritance of diapause induction and termination by crossing the two strains ...

A facultative anaerobic bacterium, strain FaiI3(T), was isolated from samples collected from the free-flowing waters of a bore well (Fairlea Bore, registration number 3768) which taps into the Australian Great Artesian Basin subsurface thermal aquifer. Strain FaiI3(T) developed yellow to pale-yellow colonies (0.5-1.5 mm) after 48 h. The non-spore forming rods (0.5x1-3 microm) were slightly curv...

OBJECTIVES To evaluate the relationship between facultative skin pigmentation, which predicts circulating levels of plasma 25-hydroxymitamin D, and several measures of bone mass and structure in a cross sectional sample of adolescent females living in Hawaii. METHODS Our sample was composed of adolescent females (n = 94) living in Hawaii where seasonal sun exposure is minimal, and who self-id...

To characterize sulfate-producing microorganisms from the deteriorated sandstones of Angkor monuments in Cambodia, strains of Mycobacterium spp. were isolated from most probable number-positive cultures. All five strains isolated were able to use both elemental sulfur (S(0)) for chemolithoautotrophic growth and organic substances for chemoorganoheterotrophic growth. Results of phylogenetic and ...

Background: Yazd waste stabilization pond facilities consist of three stabilization pond systems, module 1, module 2 and module 3 that AWSP module 1 has started its operation. The existing facilities have had several problems in their operation. The objectives of this research were to evaluate the performance of stabilization ponds in wastewater treatment of the city of Yazd, due to several pro...

Aspirates of 15 acutely and 13 chronically infected frontal sinuses were processed for aerobic and anaerobic bacteria. A total of 20 isolates (1.3 per specimen) were recovered from the 15 cases of acute frontal sinusitis, 16 aerobic and facultative isolates (1.1 per specimen) and 4 anaerobic isolates (0.3 per specimen). Aerobic and facultative organisms alone were recovered in 13 specimens (87%...

Eleven strains of halophilic, facultative anaerobes isolated from healthy and diseased Dentex dentex and Sparus aurata (bony fishes) cultured in Spanish Mediterranean fisheries have been studied by a polyphasic approach that included a wide phenotypic characterization, DNA-DNA hybridization and phylogenetic analysis using 16S rRNA, recA and rpoD gene sequences. All strains were phylogenetically...

The purpose of this study was a detailed characterization of Shewanella sp. O23S, a strain involved in arsenic transformation in ancient gold mine waters contaminated with arsenic and other heavy metals. Physiological analysis of Shewanella sp. O23S showed that it is a facultative anaerobe, capable of growth using arsenate, thiosulfate, nitrate, iron or manganite as a terminal electron acceptor...

The bacterial genus Listeria contains both saprotrophic and facultative pathogenic species. A small genome size has been suggested to be associated with the loss of pathogenic potential of L. welshimeri and L. seeligeri. In this paper we present data on the genome of L. monocytogenes strain FSL J1-208, a representative of phylogenetic lineage IV. Although this strain was isolated from a clinica...

Akinetes are spore-like resting cells formed by certain filamentous cyanobacteria that have increased resistance to environmental stress. They can be found at low frequencies in dense cultures experiencing low light or phosphate limitation, but also form at high frequencies in a zwf mutant strain of Nostoc punctiforme following dark incubation in the presence of fructose. The wild-type strain i...
