“…Sequences were analyzed (% of similarity), referring to genomic databases (EMBL-Germany, NIH-USA), with the BLAST platform [48]. The conservation and sustainable fruition of cultural assets must be based on evaluating physical, chemical, and biological factors that accelerate the deterioration process [4][5][6][7]. Concerning biological wood, decay, bacteria, fungi, and insects represent a threat to the conservation, acting by bioactive agents (such as enzymes), and hydrolysing the chemical constituents of wood (cellulose, hemicelluloses, and lignin).…”

Aromatic plants represent a source of natural products with medicinal properties, and are also utilized in the food and pharmaceutical industries. Recently, the need for eco-compatible and non-toxic products, safe for both the environment and human health, have been proposed for the sustainable conservation of historic–artistic artifacts. In this study, in order to counteract microbial colonization (Aspergillus sp., Streptomyces sp., Micrococcus sp.) on wooden artwork surfaces, Thymus vulgaris L. (Lamiaceae) essential oil (EO) and hydro-alcoholic (HA) solutions were applied in a polyphasic approach. The antimicrobial activities of EO and HA solutions were preliminarily assessed by agar disc diffusion (ADD) and well plate diffusion (WPD) in vitro methods, defining the specific concentration useful for bacterial and fungal genera, identified by optical microscopies, in vitro cultures (nutrient or Sabouraud agar), and DNA base molecular biology investigations. Specifically, the microbial patina was directly removed by a hydro-alcoholic solution (while evaluating the potential colorimetric change of the artwork’s surface) combined with exposure to EO volatile compounds, performed in a dedicated “clean chamber”. This study proposes, for the first time, the combined use of two plant extracts to counteract microbial development on wooden artworks, providing supplementary information on these products as bio-agents.

“…Protozoa and Chromista have a cosmopolitan distribution and play an integral role in the decomposition of organic matter, nutrient cycling, and maintenance of energy flow within terrestrial and aquatic ecosystems (Pournou & Pournou, 2020). They can be of low abundance, but they widespread in environments that only marginally suit their survival or can rapidly colonize and exploit microenvironments that more optimally satisfy their needs (Anderson, 1988).…”

The Mediterranean Sea receives several kinds of untreated pollution resulting from intensive human activities which affect zooplankton distribution along the sea. For this reason, the present work aimed to study the spatial and temporal distribution of zooplankton communities along the Egyptian coast of the Mediterranean Sea, with some lights shed on their diversity and abundance. To achieve this target, four seasonal cruises were carried out at three stations along the study site. The area's environmental parameters and protozoan community were seasonally addressed in 2020. A total of 94 protozoan species were identified, belonging to Foraminifera (57 species), tintinnids (33 species) and Amoebozoa (4 species). The numerical density of protozoans was high over the whole area, with annual averages of 11458 Individuals/m 3 . Summer and autumn were the most productive seasons for protozoans, while spring was the lowest. The recorded values of physicochemical parameters including transparency (0.9-2 m), temperature (19.2-33.9 o C), depth (4-6 m), salinity (30-45 ‰), water pH (6.8-8.6) and dissolved oxygen (2.15-7 mg/l) fluctuated throughout studied seasons.
