“…The concentration employed in the treatment emulsions containing the essential oils, alone (T1-T3) and combined (T7), and those containing Preventol RI-80 ® (T10 and T11), was 2% (w/w) and 2% (v/v) for T10 [25][26][27][28]. As already mentioned, the essential oils used in the study have as principal active component various phenolic compounds at certain concentrations.…”

The society has become increasingly interested in using natural products over chemicals for cleaning activities. In this study, the cleaning potential of formulations embedded in a hydrogel matrix and composed respectively of essential oils (EOs) of Origanum vulgare, Thymus vulgaris, and Calamintha nepeta, and their respective main active components (EO-ACs), viz., Carvacrol, Thymol, and Pulegone, on a phototropic biofilm growing on granite was investigated. In addition, and for comparative purposes, analysis with the combination of the three EOs, the combination of the three EO-ACs, and Preventol RI-80® (one of the most effective commercial cleaning agents based on quaternary ammonium salts) in all three cases embedded in a hydrogel matrix, as well as only the hydrogel matrix, distilled water, and Preventol RI-80®, in both latter cases applied with brush, were also studied. The cleaning effect of the treatments was assessed immediately after the treatment and after one and two weeks by color spectrophotometry, a reliable tool to evaluate the presence and vitality of the phototrophs and the cleaning effectiveness in granite. C. nepeta and its active component Pulegone proved to be the most effective and yielded similar results, comparable to those of uncolonized granite, and better than those obtained with Preventol RI-80® applied with brush (most common way), especially at the end of the experiment. These promising first results support the suitable use of the phytochemical compounds used on phototrophs field where there are still few published studies and encourage further investigation toward the evaluation of their exhibited biocidal activity.

“…In these conditions, the prevention of biofouling growth can be achieved either by the selection and application of high resistance coating materials to natural thermooxidative processes (thermal stress and UV action [6,13,14,16] and the molds action [8,10,15]), or through the use of appropriate antifungal biocides [35][36][37][38][39][40][41] (obviously with the necessary precautions -taking into account that the investigated bridge is in the Natura 2000 protected area [24]).…”

The species from the increased biofouling on the paint layers applied to the metallic strength structure of a railway bridge located in a Natura 2000 protected area have been identified by specific biologic and microbiological methods. As a result of the analysis of the biological samples taken on the field, it has been found that relatively large variety of filamentous molds are present (Aspergillus fumigatus, Asprgillus flavus, Aspergillus niger, Paecilomyces variotii, Chaetomium globosum, Trichoderma viride, Stachybotris atra, Trichoderma sp., Alternaria sp and Penicillium sp.). Samples also show, lichens (Xanthoria parietina and Hypogymnia physodes) and lower plants capable of photosynthesis such as algae (Chlorophyta Xanthophyceae, Chrysophyceae) and moss (Lunularia cruciata, Marchantiophyta).

“…Although many of the more toxic biocides have been banned, safer compounds may have some drawbacks. For example, the effectiveness of quaternary ammonium salts (e.g benzalkonium chloride) to disrupt cell membranes and kill lithobionts has been well demonstrated (Wessels and Ingmer 2013; Vannini et al 2018;Sanmartín et al 2020), but their use can promote bacterial adaptation and antibiotic resistance (Kampf 2018;Kim et al 2018;Poursat et al 2019). Moreover, their degradation is suspected to contribute to nitrogen supply (Scheerer et al 2009), thus favouring, rather than preventing, recolonization by aggressive nitrophytic species.…”
