Background. The growing resistance of microorganisms to antimicrobial agents is a pressing public health issue. Bioprospecting efforts have mainly focused on well-known environments such as soil and animal gut in search for with antibiotic production or activity, terrestrial ecosystems endemic plants bioactive compounds. However, microbial communities thriving stressed hot springs, are potentia...

Colletogloeopsis zuluensis, previously known as Coniothyrium zuluense, causes a serious stem canker disease on Eucalyptus spp. grown as non-natives in many tropical and sub-tropical countries. This stem canker disease was first reported from South Africa and it has subsequently been found on various species and hybrids of Eucalyptus in other African countries as well as in countries of South Am...

New diorganotin(IV) complexes of the type Ph2SnL2, Bu2SnL2 and Me2SnL2 of the ligands 2-thioacetic-5-phenyl-1,3,4-oxadiazole (HL) and benzamidophenylalanine (HL). Have been synthesized and characterized by physico-chemical techniques such as (elemental analysis, and electrolytic conductance) and spectral UV-Visible, IR and H, C and Sn NMR). Monomer structures for the complexes, bidentate and oc...

A detailed study of ascomal morphology and development in Cercophora palmicola showed that ontogeny is ascohymeniaceous, giving rise to an ostiolate perithecium. Ascomal initials consist of a coiled ascogonium surrounded by several layers of hyphae whose cells become pseudoparenchymatous. The centrum of the young ascoma is composed of a few rows of large, thin-walled pseudoparenchymatous cells ...
