To sustain and guarantee an adequate yield of tomato crops, agricultural practices have been based on the intensive use of fertilisers with negative impacts on the environment. An eco-friendly and sustainable alternative to the traditional cultivation methods is the bioaugmentation approach, using tailor-made microbial consortia. Eight indigenous strains, isolated from the soil of “Terra-Sole” farm in the coastal plain of Pula (Sardinia - Italy), were selected in the laboratory for their plant growth promoting (PGP) functions. The beneficial effects of the bacterial formula, including genera Delftia, Pseudomonas, Paenarthrobacter, Phyllobacterium, Bacillus, and Acinetobacter, were tested in three subsequent field trials carried out at the company greenhouse, with different tomato varieties (Camone, Oblungo, Cherry). The results indicate that the inoculation of the indigenous bacterial formula repeat...

Fresh rock and sandstone surfaces of buildings are quickly colonized and covered by a layer of microorganisms, including phototrophs, lithotrophs, and heterotrophs to form a biofilm that alters the local conditions of the stone surfaces, especially under the favorable tropical climate conditions for autotrophic microorganisms and plants. Biofilms had been studied with indigenous or pure cultures of isolated microorganisms, but the selective ones that contribute to deterioration of the cultural heritage cannot be confirmed easily. Currently, high-throughput sequencing and metegenomics analyses are capable of obtaining microbial community and composition in great depth, but they also suffer from similar weakness unable to identify the culprits in the community. With these as background, this article prese...

In general sediments are considered to be important for assessing anthropogenic impacts on coastal and estuarine environments; however, there is no indication about which matrices are to be sampled, or for which specific pollutants. The importance of biological indicators to assess the ecological quality of coastal and estuarine zones is also emphasised. Taking into account the requirements of the WFD, we propose a multiparametric index, the Lagoon Quality Triad, as a tool to assess the quality of shallow coastal ecosystems and to easily monitor the changes in time. It is based on three complementary parameters, which consider different time scales and ecosystem compartments, such as: water, sediment and biota. A notable effort has been made to choose, among all the parameters analysed, those which resulted to be more easy to obtain, not ...

Among the methods for its production, the most promising and environmentally friendly one seems to be the dark fermentation of organic wastes as it solves both the problem of waste disposal and allows to obtain energy and value-added chemicals. One way to improve the efficiency of H2 production is to explore the biodiversity, identify and to select bacterial strains with high H2 producing abilities from different substrates, and to characterize the microbial metabolism, in order to understand and optimize the whole process. Only after exploring the potentials offered by the biodiversity we will be really able to identify the best candidates which could be, for instance, used for genetic engineering, in order to enhance (or inhibit) some required characteristics. This approach consists of two main aims: 1) to isolate and to identify potential H2 pr...

A monitoring system was set up in both lagoons in order to (i) map the distribution of macrophytes, (ii) measure spatio-temporal changes in the biological parameters of the seagrasses, and (iii) measure spatiotemporal changes in biological and chemical-physical parameters in the water column and sediments. 3. The results showed that the relationships between macrophytes and aquatic and sediment compartments entail functional differences described by buffering systems that counteract the accumulation of free sulphide. 4. This study also suggests that R. cirrhosa and C. nodosa are indicators of different levels of ecological stability.

The Water Framework Directive uses the ''one-out, all-out'' principle in assessing water bodies (... more The Water Framework Directive uses the ''one-out, all-out'' principle in assessing water bodies (i.e., the worst status of the elements used in the assessment determines the final status of the water body). In this study, we assessed the ecological status of two coastal lakes in Italy. Indices for all biological quality elements used in transitional waters from the Italian legislation and other European countries were employed and compared. Based on our analyses, the two lakes require restoration, despite the lush harbor seagrass beds, articulated macrobenthic communities and rich fish fauna. The ''one-out, all-out'' principle tends to inflate Type I errors, i.e., concludes that a water body is below the ''good'' status even if the water body actually has a ''good'' status. This may cause additional restoration costs where they are not necessarily needed. The results from this study strongly support the need for alternative approaches to the ''one-out, all-out'' principle.

Such comprehension could launch several innovations relating to natural and cultural capital, including historical and artistic heritage. In relation to cultural heritage, microorganisms are mainly known through their role as deteriogens, but the features creating damage can be exploited positively, attaining more sustainable restoration strategies, in accordance with the principles of compatibility and retreatability deriving from reflections on the Cultural Heritage inspired by the Charter of Venice (International charter for the Conservation and restoration of monument and sites (the Venice Chart 1964). In: ICOMOS, IInd International Congress of Architects and Technicians of Historic Monuments, 1964) onwards. In this article, we show a series of case studies, u...

Many of the stone walls of the prestigious Domus Aurea are overwhelmed by dense biofilms and so need intervention. Room 93 was chosen as a study site with the aim to test the efficacy of phyto-derivatives as new biocides. Laboratory studies were performed comparing the effects of liquorice leaf extract (Glycyrrhiza glabra L.), lavender essential oil (Lavandula angustifolia Mill.) and a combination of both. In situ studies were also performed to test the effect of liquorice. The results were compared with those of the commonly used synthetic biocide benzalkonium chloride. The effects on the biofilms were assessed by microscopy along with chlorophyll fluorescence analysis. The phototrophs in the biofilms were identified morphologically, while the heterotrophs were identified with culture analysis and 16S gene sequencing. Results showed that the mixed solution liquorice/lavender was the...

Studies have shown that sediment characteristics are important in determining submerged aquatic vegetation growth, germination, survival, and distribution. On the other hand the vegetation influences some characteristics of sediments too. The main goal of this study was to relate the dominant seagrass distribution of two coastal lagoons, in the Circeo National Park, to sediment characteristics. Biochemical composition of organic matter showed a different quality and origin, according to the different submerged vegetation. The first lagoon, dominated by Cymodocea nodosa, was characterised by a high amount of refractory OM (higher OC and C/N), while the second one, dominated by Ruppia cirrhosa, was characterised by a more labile OM, with a higher contribution of proteins. The protein to carbohydr...
