We evaluated the ability of heavy metals (copper, lead) to alter lipid metabolism in four algal
lichen photobionts following short term exposure. Metal concentrations (10μM) were …

Copper-sensitive (Cu s) and copper-resistant (Cu r) strains of Pseudomonas aeruginosa
were characterized in terms of Cu 2+ sensitivity, uptake and its compartmentalization in the …

The ability of microorganisms to selectively adsorb various heavy metal ions has been
recognized for over a decade. We have investigated the biosorption of lead by an active …

Anacystis nidulans, an isolate from the polluted waters, was able to grow in Chu-10 medium
with Cr up to 100 μM concentration. Free and agar immobilized cells of the organism having …

Exudates by marine phytoplankton and metals coexist in the seawater, but little is known
about their interaction. In this study, cultures of Prorocentrum donghaiense Lu were grown in …

We investigated the influences of different nutrient regimes on the accumulation of Cd, Zn,
and Se (IV) in the freshwater green alga Chlamydomonas reinhardtii over a 4 h exposure …

The effects of Ni, Cu and Hg on thiol and exopolysaccharide synthesis in Nostoc
spongiaeforme has been investigated. LD50s for Ni, Cu and Hg based on the specific …

Trace metals are required for many cellular processes. The acquisition of trace elements
from the environment includes a rapid adsorption of metals to the cell surface, followed by a …

Pseudomonas aeruginosa cells growing in minimal medium were 40-fold more sensitive to
Ni 2+ than cells growing in enriched medium, suggesting a possible protective role of …

The sorption of Ni from aqueous solution using fly ash, CaCO3 and sawdust preparations
from pine (Pinus roxburghii) and cedar (Cedrus deodara) was investigated. Fly ash with a …
