Desert truffles are edible ascomycete fungi. These mushrooms are economically important and widely distributed in arid and semi-arid regions of Tunisia. This study aims to characterize the germination of Terfezia boudieri Chatin that would be important to isolate homokaryotic hyphae. Ascocarps of T. boudieri were collected from the southeast of Tunisia. Ascospores germination was tested on three culture media: Malt extract agar 1%, Melin Nokrans modified and the Potato dextrose agar. The germination was only observed on Malt extract agar 1% medium and germinating rate was in order of 4%. Isolation of germinating hyphae was successful. These hyphae derived from two material, i.e., from a single ascospore and from ascospore inside asci. Source

Pistacia lentiscus seed oil is a natural product widely used for culinary and medicinal purposes in Algerian and Tunisian forest areas. Until now, the quality of this oil is still not well known. This study aims to optimize its quality by determining the best period to harvest fruits. Quality criteria include fatty acid composition and antioxidant activity of this oil. Fruits were harvested during three maturity stages: unripe, ripe and over ripe. Oleic acid was the major fatty acid (more than 40%), followed by palmitic (22.28-28.6%) and linoleic (13.63-20.5%) acids. Antioxidant activity was estimated using DPPH scavenging ability and Trolox Equivalent Antioxidant Capacity (TEAC) assays. Oil extracted from the pulp at over-ripeness showed the highest percentage of inhibition of DPPH with about 37% corresponding to 80 ng of Trolox/g of oil. Source

Pistacia lentiscus L. is known in some Tunisian forest area by its fixed oil used in traditional medicine as an antiseptic product. This investigation is the first to study the antimicrobial activity of P.lentiscus edible oil and its phenolic extract. Oil was extracted from fruits harvested from six provenances located in Tunisia. The antimicrobial activity was tested using disc diffusion assay and the broth dilution method. Kbouch and Sidi Zid oils were most efficient (p < 0.003) against, respectively, Staphylococcus aureus and Aspergillus niger with an inhibition zone of 9.33 mm. The phenolic extract had the largest spectrum of sensitive microorganisms. The minimum inhibitory concentration and minimum bactericidal concentration results showed that all strains were inhibited by both oil and extract. © 2014 © 2014 Taylor & Francis. Source
