The most important plant species employed in reforestation programs depend on ectomycorrhizal fungi for their establishment and growth. The exploitation of this symbiosis to improve forest productivity requires fungal inoculants in a large scale level. To develop such a technology it is necessary to define the optimal composition of the culture medium for each fungus. With these objectives in m...

The co-substrate is a crucial component in the bio-decolorization process that helps bacteria to grow and carry out their fundamental functions. Different types of textile dyes with diverse chemical structures are frequently employed industry, most them resistant biodegradation because xenobiotic nature. Due low carbon content dyes, particularly azo co-metabolic conditions required for decolori...

It is not yet known what properties distinguish macrophages which can kill facultative intracellular bacteria, such as Listeria monocytogenes, from those which cannot. Listeria is an organism which requires iron for growth, yet macrophage listericidal mechanisms are also likely to be iron dependent. We show here that resident peritoneal macrophages and thioglycollate-elicited macrophages cannot...

Nattokinase, primarily isolated from a traditional fermented food in Japan---“ Natto” , is a novel fibrinolytic enzyme. It is considered to be a promising agent for thrombosis therapy. The composition of the medium for the production of nattokinase by Bacillus natto NLSSE was optimized with a stepwise strategy. Effects of various nitrogen and carbon sources were investigated. Among the tested n...
