Antimicrobial Activity of the Desert Truffles "Tirmania pinoyi" and "Terfezia claveryi" Against Human Pathogens

2015

The development of novel antimicrobials in the struggle against pathogens and antibiotic resistance is one of the most important global challenges of our time. Medicinal mushrooms represent an unlimited source of polysaccharides with nutritional, antitumoral, antibacterial and immune stimulating properties1. In recent years the traditional studies on epigeous higher Basidiomycetes have been joined by those on hypogeous fungi and in particular on the so-named “desert truffles”. Ali2 demonstrated that organic extraction of truffles of genus Tirmania and Terfezia possess antimicrobial activity with broad-spectrum effects against Gram positive, Gram negative, aerobic and anaerobic bacteria …

New antimicrobial peptides from Tirmania pinoyi and Terfezia boudieri in the struggle against antibiotic resistance

2017

Antibiotic resistance of common pathogenic microorganisms is a topic of great concern that has finally received media attention and entered into the political agenda of world leaders. Drug-resistant bacteria are cause of thousands of deaths worldwide, then there is an urgent need for new antimicrobials, otherwise we risk losing the ability to control effectively the infectious diseases. Such emergence can be faced looking also at not usual source of antimicrobial agents, for example medicinal mushrooms. With the objective to tackle Gram-positive and Gram-negative pathogens, we focused on two edible desert truffles mushrooms Tirmania pinoyi and Terfezia boudieri as origin of new antimicrobia…

Sustainable management systems to prevent and adaptat to desertification: Case Studies from the LIFE Desert Adapt project

2021

Around 40% of the ice-free terrestrial surface is under desertification risk, and the Mediterranean is one of the most sensible regions. Concomitantly, most areas occupied by agriculture suffer from lack of organic matter in the soil, as well as very low tree cover, making them more vulnerable to climate change. The LIFE (Desert Adapt) project aims to develop a desert adaptation model to enhance resistence and resilience of farms, both public and private, to desertification by appliyng an integrative sustainable land management in Italy, Spain and Portugal. In Italy three sites in Sicily are involved, two private areas in Caltanissetta and Catagirone and the municiaplity of Lampedusa.The mo…

Bird abundance and richness in ten Mediterranean agroforestry systems

2019

Since the last century agriculture is strongly promoting the simplification of the landscape. The LIFE Desert Adapt project is been developed across 1000 hectares in Italy, Spain, Portu-gal and has the objective of implementing integrative agroforestry-based land use planning and management, and one of the indicators to evaluate the project effectiveness is birds richness and abundance. Here we present the results of the first assessment and explore the relationships with the main vegetation cover types. We established 68 sampling points where we recorded bird abundance and richness. In total we registered 57 bird species, sampling points surrounded by woodlands presented 50 species, while …

The transformation of agricultural systems into agro-forestry systems as a system of adaptation to climate and economic changes: some Sicilian case s…

2021

Many traditional agricultural systems show different limits both in ecological and economic terms. These limits are exacerbated by the increasingly extreme climatic conditions which in the southern regions are manifested essentially in a concentration of rainfall and in increasingly intense dry periods. As part of the LIFE (Desert Adapt) project, some companies involved in the project are modifying their cultivation systems without changing the land use destination. This appears possible by introducing elements of diversification which make the system more resilient as a whole but which guarantees safer economic resources. In particular, in the case of a "classic" agricultural company Calta…
