Abstract Background and objectives: Germ tube-producing ability of C.albicans in human serum is one of the most important virulent factors inducing transformation yeast to mycelia form. This phenomenon can be altered by some environmental and nutritional factors. The purpose of this study was to investigate the effect of temperature, pH and glucose concentrations in germ tube formation of C. al...
both climate change and anthropogenic impact are creating a dynamic of continuous changes in ecosystems. while the expected consequences of these changes are global, the occurrence of extreme events and specific environmental problems are usually local or regional phenomenon. in particular, the coastal ecosystems are among the first vulnerable areas to show those changes; in spite of this, are...
abstract amino acids are building blocks of proteins, and play a vital role in living beings existence and their functionality. the interaction of these compounds with metal ions is of great importance to biochemists, and chemists, because their functions can be utilized as a model in understanding enzymes mechanism for transport of metal ions to tissues. among twenty essential amino acids w...
fruit waste extract was selected as the sole substrate for carotenoid production and the effect of parameters like ph, temperature and agitation have been studied. a two-step simple sequential strategy was employed for the optimization of carotenoid production by rhodotorula rubra. in the first step, one factor at a time was employed to evaluate the impact of ph on carotenoid production. the ou...
Carbon nanotubes (CNTs) have very promising applications for inhibition of microbial growth. The aim of this study is investigation and comparison of the effect of temperature and acidity on antimicrobial activities of pristine Multiwalled Carbon nanotubes (MWCNTs) and Multiwalled Carbon nanotubes-Arginine (MWCNTs-Arg). Minimum Inhibitory Concentration (MIC) and Minimum Bactericidal Conc...

Oceanic uptake of anthropogenic carbon dioxide results in decrease in seawater pH and increase in temperature. In this study, we demonstrated the synergistic effects of elevated seawater temperature and declined seawater pH on gene expression patterns of aspein, calmodulin, nacrein, she-7-F10 and hsp70 in the pearl oyster Pinctada fucata. Under 'business-as-usual' scenarios, four treatments wer...
