| Combining culture-dependent and independent approaches, we investigated for the first time the cultivable fraction of the prokaryotic community associated with the carnivorous sponge Asbestopluma hypogea. The heterotrophic prokaryotes isolated from this tiny sponge were compared between specimens freshly collected from cave and maintained in aquarium. Overall, 67 isolates obtained in pure culture were phylogenetically affiliated to the bacterial phyla Proteobacteria, Bacteroidetes, Actinobacteria, and Firmicutes. This cultivable diversity was lower than the prokaryotic diversity obtained by previous pyrosequencing study and comparable to that of another Mediterranean demosponge, the filter-feeding Phorbas tenacior. Furthermore, using fluorescence in situ... |

| Saline soil was amended with 13.3 and 26.6 g kg-1 of Municipal Solid Waste (MSW) compost or sewage sludge, and arylsulphatase (ARY), phosphatase (PHO), dehydrogenase (DEH), (β-glucosidase ((β-GLU), urease (URE) and catalase (CAT) activities as well as physical-chemical properties were determined after 70 day of incubation under laboratory conditions. MSW compost and sewage sludge significantly improved soil physical-chemical properties, especially carbon and nitrogen contents. Accordingly, overall enzyme activities were substantially promoted in presence of both amendments and the higher increases were measured at 13.3 g kg-1 of MSW compost (increases by 107%, 43%, 20%, 11%, and 148% for, DEH, (3-GLU, PHO, URE, and CAT, respectively).... |
