The endolithic microbial communities of the Antarctic represent a borderline lifestyle in the most hostile ice-free areas of the continent. The extreme adaptation of microbes in these communities renders them very sensitive to environmental changes. To date, the actual distribution of these communities has never been investigated; yet, this information would define the geographic limits for life at...
Abstract. Isolation by a dilution plate method from Pb-polluted soil samples allowed us to select a Pb-resistant strain of Paecilomyces lilacinus, which was able to grow in media containing up to 1,437mg Pb l1. Tests on the actual Pb availability in amended culture media indicate that medium components bind most of the added Pb (7198.5%, depending on the amount added and on the pH reached). Sorption...
