Benthic primary producers in tropical reef ecosystems can alter biogeochemical cycling and microbial processes in the surrounding seawater. In order to quantify these influences, we measured rates of photosynthesis, respiration, and dissolved organic carbon (DOC) exudate release by the dominant benthic primary producers (calcifying and non-calcifying macroalgae, turf-algae and corals) on reefs ...

abtalkh formation is a part of late cretaceous sedimentary unit in the kopet- dagh basin, ne iran. this study deals with the study of this formation in the eastern parts of the basin in padeha village. it thickness is about 991m, and lithologically consists of grey, greyish to blue shale and marl. the lower contact with abderaz formation is conformable and transitional, but the upper boundary w...

the present study aims to have a comparative study of the results, from biological monitoring as well as conventional method, based on physico-chemical variables. water quality index (wqi) and planktonic diatom metrics have been used to determine water quality and ecological conditions of the dong nai river (dnr) and canonical correspondence analysis (cca) to find out the main environmental var...

conclusions bacterial resistance against quaternary ammonium compounds is increasing which can increase the bacterial biofilm formation. results the means of strains growth increase after the minimal inhibitory concentration (mic) were significant in all the bacteria (except for e. coli in 1/32 and s. agalactiae in of 1/8 mic). biofilm formation increased with decrease of antiseptics concentrat...

A latest Maastrichtian global warming event, which began approximately 450 k.y. and ended about 22 k.y. prior to the K/T boundary, is associated with the poleward migration of the warm-water planktonic foraminifer Pseudotextularia elegans. The warming event was apparently inititated by greenhouse warming due to the main outpouring of the Deccan Traps in India and is now well documented in the N...

Methicillin-resistant Staphylococcus aureus (MRSA) is one of the most threatening pathogens due to its multi-drug resistance (MDR) and strong biofilm-forming capacity. Here, we described the screening of a novel chimeolysin (ClyF) that was active against planktonic and biofilm MRSA. Biochemical tests showed that ClyF was active against all S. aureus clinical isolates tested under planktonic and...

Cryptococcus neoformans and C. gattii are fungal pathogens that are most commonly found in infections of the central nervous system, which cause life-threatening meningoencephalitis and can grow as a biofilm. Biofilms are structures conferring protection and resistance of microorganism to the antifungal drugs. This study compared the virulence of planktonic and biofilm cells of C. neoformans an...
