Assessing Heavy Metals Pollution of the Mangrove Sediments along Tidal Flat of the Mehran River Delta, Persian Gulf
The relationship between the concentration of heavy metals and physicochemical factors was studied in the fine-grained sediments of the tidal section of the Mehran delta where mangrove trees have grown. Surface sediments of the tidal zone of the Mehran delta were sampled. The grain size distribution, calcium carbonate, organic matter contents, pH/Eh, and heavy metals concentration were determin...
متن کاملMorphological Association of Microbially Induced Sedimentary Structures (miss) as a Paleoenvironmental Indicator: an Example from the Proterozoic Succession of the Southern North China Platform
The Ruyang (Mesoproterozoic; Pt2) and Luoyu (Neoproterozoic; Pt3) groups in the southern North China Platform are dominated by peritidal siliciclastic rocks and contain abundant microbially induced sedimentary structures (MISS), including multidirected and mat-protected ripple marks, mat chips, mat-smoothed ripple marks, various sand cracks, and irregular growth ridges. These MISS can be groupe...
متن کاملDiatom Ecology and Microbial Mat Structure and Function in Antarctic Dry Valleys
Streams in the McMurdo Dry Valleys of Antarctica (MDV) are harsh habitats for life. Months of perpetual darkness and subzero temperatures are punctuated by months of perpetual sunlight, intense UV radiation, and temperatures that hover around freezing. The availability of liquid water regulates biological activity and limits the growing season to 6–10 weeks each year. These harsh conditions lik...
متن کاملA novel psychrophilic alkaline phosphatase from the metagenome of tidal flat sediments
BACKGROUND Alkaline phosphatase (AP) catalyzes the hydrolytic cleavage of phosphate monoesters under alkaline conditions and plays important roles in microbial ecology and molecular biology applications. Here, we report on the first isolation and biochemical characterization of a thermolabile AP from a metagenome. RESULTS The gene encoding a novel AP was isolated from a metagenomic library co...
