A large-scale multiple genome comparison of acidophilic archaea (pH ≤ 5.0) extends our understanding of oxidative stress responses in polyextreme environments
(2022-01)
Acidophilic archaea thrive in anaerobic and aerobic low pH environments (pH < 5) rich in dissolved heavy metals that exacerbate stress caused by the production of reactive oxygen species (ROS) such as hydrogen peroxide (H2 ...
EVALUATION OF HVOF SPRAYED WC-13Co-4Cr AND HARD CHROMIUM ELECTROPLATED ON STAINLESS STEEL 15-5PH FATIGUE STRENGTH
(Inegi-feup, 2017-01-01)
Fatigue failure is the result of a crack initiation and propagation as a consequence of cyclic loading. In the aeronautical industry, for components like landing gear, fatigue strength is an important parameter to be ...
Caracterização do mecanismo de controle do pH no tubo digestivo de Lutzomyia longipalpis (Lutz e Neiva, 1912) (Diptera: Psychodidae) e sua importância no desenvolvimento de Leishmania Ross, 1903
(Universidade Federal de Minas GeraisUFMG, 2010-09-10)
The midgut pH control is a key step during Lutzomyia longipalpis digestion process. Phlebotomines have to change from a favorable carbohydrate digestion (luminal pH = 6) to blood digestion (luminal pH~8). Until blood ...
Effect of pH on the ultrastructure of the conidial wall of Aspergillus Niger aggregate conidia and its relationship to zearalenone adsorption
(Wageningen Academic Publishers, 2016-12)
The purpose of the present study was to evaluate the effect of pH on the ultrastructure of the conidial wall of dead conidia harvested from the non-toxicogenic Aspergillus Niger aggregate strain RC084 and its relationship ...

L(+) Lactic acid production by new Lactobacillus rhamnosus B 103
(2010-05-01)
L(+) Lactic acid fermentation was studied by Lactobacillus rhamnosus sp. under the effects of pH control and a lowcost nutritional medium (sugarcane juice and corn steep liquor-CSL). Central composite design (CCD) was ...
