Rotolo, V., De Caro, M. L., Giordano, A. & Palla, F.: Solunto archaeological park in Sicily: life under mosaic tesserae. -Fl. Medit. 28: 233-245. 2018. -ISSN: 1120-4052 printed, 2240-4538 online.Biodeterioration is a complex process induced by the growing and metabolic activity of a wide range of macro and microorganisms, becoming a revelling problem also for the mosaic tesserae of "Casa di Leda" in the Greco -Roman site of Solunto in Sicily. In this case-study, a thick biofilm inducing a deep alteration of mortar and consequently the mosaic tesserae detachment has been highlighted during the restoration plan. The biofilm microbial consortium has been investigated by an integrate approach based on Microscopy analysis (O.M., C.L.S.M.), in vitro culture (Nutrien and Saboraud media) and molecular biology investigation (DNA target sequence amplification, sequencing, sequence analysis). A microbial diversity has been revealed belonging to bacteria (Bacillus) and fungi (Alternaria, Aspergillus), besides cyanobacteria (Chroococcus) and green algae (Chlorella). In order to control the biofilm colonization two essential oils (EO), Thymus vulgaris and Origanum vulgare, have been utilized and their antimicrobial activity, preliminarily in vitro (agar disc diffusion methods) and after ex situ and in situ evaluated. This experimentation is aimed at identifying and implementing green biocides for the control of microbial colonization, a promising technology with a reduced impact on human health and environment, able to replace traditional biocide action.

“…The antifungal activity assay against the growth of Trametes versicolor, and Coniophera puteana, was performed following Salem et al (2014). About 15 mL potato dextrose agar (PDA) medium containing the concentrated extract (1000, 2000 μL) was poured into each petri dish and allowed to solidify.…”

“…Significant antifungal effects were observed on the growth media treated with bark extracts of Carya ovata, Quercusrubra and Pinus strobus (Harun and Labosky, 1984). The bark extract of Delonix regia was found the maximum percentage inhibition of fungal mycelial growth against Penicillium selerotigenum (70.37%) and Paecilomyces variotii (77.78%) by Salem et al (Salem et al, 2014).…”

Aim of study: The need for eco-friendly and bio-soluble wood preservatives has increased recently. In this study, antifungal effects of tree barks were researched. Area of study: The maritime (Pinus pinaster L.), iron (Casuarina equisetifolia L.), mimosa (Acacia mollissima L.), calabrian pine (Pinus brutia Ten.), and fir (Abies nordmanniana) tree barks were used. Material and Methods: The the solution at two concentrations was prepared to the substance obtained with alcohol benzene extraction method from the tree bark according to TAPPI standard. The effectiveness of bark extracts was evaluated against brown-rot fungus; Coniophera puteana, and white-rot fungus; Trametes versicolor. Main results: This study indicates that tree bark extracts have potential to use as wood preservatives. Maritime pine and fir tree barks showed good resistance against T. versicolor more than C. puteana. On the contrary, iron and mimosa tree barks were more resistance against brown-rot fungus, C. puteana. Concentration is the most important factor for inhibition of fungal activity. Inhibition of fungal growth increased parallel with concentration. Research highlights: It is thought that the rich structure of the bark extract in terms of natural phenolic compounds could inhibit fungal activity. This study indicates that tree bark extracts have potential to use as wood preservatives.

The natural durability of wood to mold fungi was tested under laboratory conditions with locally sourced Citharexylum spinosum and Morus alba woods. The mold fungi were Penicillium selerotigenum, Paecilomyces variotii, and Aspergillus niger. Changes in surface elemental composition were evaluated with energy dispersive X-ray spectroscopy (EDX) and the biodeterioration of wood surfaces by scanning electron microscope (SEM). The C peak element of C. spinosum wood was affected significantly (P = 0.0004) and decreased from 49.91% in the control specimens to 47%, 40.1%, and 40% with P. selerotigenum, A. niger, and P. variotii, respectively. Also, the C peak element of M. alba heartwood significantly decreased (P < 0.0001) from 51.33% in the control specimens to 41.49%, 45.66%, and 43.66% in wood inoculated with A. niger, P. variotii, and P. selerotigenum, respectively. The elements Al and Cu were observed in high percentages with M. alba heartwood inoculated by P. variotii. The methanol extract from M. alba heartwood showed good inhibition against the growth of A. niger at a concentration of 32 μg/mL, and the methanol extract from C. spinosum wood showed remarkable inhibition against the growth of P. variotii at a concentration of 8 μg/mL. The results of this study clearly showed the changes that occur in wood samples as a result of fungal infestation.
