Biological control of soil-borne phytopathogenic fungi through onion waste composting: implications for circular economy perspective

Consumers’ Perspective on Circular Economy Strategy for Reducing Food Waste

The current linear system of production and consumption is unsustainable. In the food sector, despite the fact that valuable natural resources are intensively used to produce and distribute food products, little is done to upcycle residues generated along the supply chain. Circular economy strategies are crucial for restructuring the take-make-dispose model through the active participation of a...

Waste and circular economy

Rhizobia as a biological control agent against soil borne plant pathogenic fungi.

Rhizobia promote the growth of plants either directly through N2 fixation, supply of nutrients, synthesis of phytohormones and solubilization of minerals, or indirectly as a biocontrol agent by inhibiting the growth of pathogens. The biocontrol effect of rhizobia is due to the secretion of secondary metabolites such as antibiotics and HCN. Siderophore production in iron stress conditions provid...

Municipal Solid Waste Composting: Biological Processing

composting process, as one or the other is normally a limiting factor. Carbon serves primarily as an energy source for the microorganisms, while a small fraction of the carbon is incorporated in their cells. Nitrogen is critical for microbial population growth, as it is a constituent of protein which forms over 50 percent of dry bacterial cell mass. If nitrogen is limiting, microbial population...

Proteins and peptides for the control of phytopathogenic fungi

Plants are exposed to a large number of pathogenic fungi. Although they do not have an immune system, plant have evolved a variety of potent defense mechanisms, including the synthesis of low molecular weight compounds, proteins, and peptides that have antifungal activity. These proteins appear to be involved in either constitutive or induced resistance to fungal attack. Generally, these protei...
