Prospecting of local grapevine (Vitis vinifera L.) germplasm revealed that Tunisia possesses a rich patrimony which presents diversified organoleptic characteristics. However, viral diseases seriously affect all local grapevine cultivars which risk a complete extinction. Sanitation programs need to be established to preserve and exploit, as a gene pool, the Tunisian vineyards areas. The presence of the Grapevine leafroll associated virus-3 (GLRaV-3), Grapevine stem pitting associated virus (GRSPaV) and Grapevine virus A (GVA), were confirmed in a Tunisian grapevine cultivar using serological and molecular analyses. The association between GRSPaV and GVA viruses induces more rugose wood symptoms and damages. For this reason the cleansing of the infected cultivar is highly advisable. Direct and recurrent somatic embryos of cv. 'Hencha' were successfully induced from filament, when cultured on $Ch{\acute{e}}e$and Pool (1987). based-medium, enriched with $2mg1^{-1}$ of 2,4-dichlorophenoxyacetic acid and $2.5mg1^{-1}$ of Thidiazuron, after 36 weeks of culture. After six months of acclimatization, RT-PCR carried on 50 somaplants confirmed the absence of GVA, GRSPaV as well as GLRaV-3 viruses in all somaplants. Ampelographic analysis, based on eight OIV descriptors, was carried out on two years acclimated somaplants, compared to the mother plant. Results demonstrated that the shape and contours of 46 somaclones leaves are identical to mother plant leaves and four phenotypically off-type plants were observed. The healthy state of 100% 'Hencha' somaclones and the high percentage of phenotypically true-to-type plants demonstrate that somatic embryogenesis is a promising technique to adopt for grapevine viruses elimination.

Anti-bacterial nanocomposites (NC1–NC4) based on cellulose acetate were prepared by dispersing ZnO nanofillers in the cellulose acetate matrix. Anti-bacterial nanocomposites were structurally and morphological examined by XRD (X-ray powder diffraction), FESEM (field emission scanning electron microscopy), and FT-IR (Fourier transform infrared) spectroscopy. All the spectroscopic techniques suggested that nanocomposites are successfully synthesized. All the nanocomposites showed antibacterial activity which increased as a function of zinc oxide. Further the selectivity of anti-bacterial nanocomposites was investigated toward different metal ions, including Zn2+, Cd2+, Pb2+, Mn2+, Ni2+, Fe2+, Al3+, Sb3+, and Sr3+. The selectivity data suggests that nanocomposites are more selective toward Fe2+. NC1 displayed highest uptake aptitude for Fe2+ with highest distribution coefficient of 7549.123 mL g1. Therefore, NC1 was subjected to water permeability to explore the role of antibacterial nanocomposite as membrane for water purification. The results suggest that these materials are possibly appropriate for water treatments.
