Background: Biological soil crusts (BSCs) that are able to produce sticky extracellular polymeric substances (EPS) play an important role in the formation of soil aggregates, thereby, reducing soil erosion. In this study, experiments were undertaken to identify biocrust species that produce EPS, in order to combat desertification in the Sejzi desert of Iran. Methods: A biocrust distribution map of Sejzi plain was prepared using Landsat 8 OLI images, then, various sampling points were selected. … Read more...

Zeybek U. & Yıldız A. (2000): Untersuchungen über die nordost-anatolischen Flechten Lobaria scrobiculata und L. pulmonaria [Studies on the Northeast Anatolian lichens Lobaria scrobiculata and L. pulmonaria] - Scientia Pharmaceutica, 68(3): 317–321

The secondary metabolites in Lobaria pulmonaria and L. scrobiculata collected in northeast Anatolia are studied using HPLC. Constictic, nortictic and stictic acids are the major components in L. pulmonaria; in addition connorstictic, cryptostictic, and menegazziaic acids are present as minor constituents. In L. scrobiculata constictic, stictic, and usnic acids and m- scrobiculin are the major compounds; while cryptostictic and norstictic acids, and p- scrobiculin are present as minors.

Naturally occurring compounds can have protective effects towards mutagens and carcinogens as shown by numerous studies. In the present study, the genotoxic/antigenotoxic activities of the extract from lichen Cetraria aculeata (Schreb.) Fr., which has been identified as an antibacterial agent in former studies, were investigated against known mutagens such as 4-nitro-o-phenylenediamine (4-NPD) and 2-aminofluorene (2-AF) in TA98 and TA100 strains of Salmonella typhimurium in the presence or absence … Read more...

Zezza F. (2006): Failure of Anisotropic Marble: The Proconnesium Marmor of Roman Columns in Brindisi - In: Kourkoulis S.K. (ed.), Fracture and Failure of Natural Building Stones, p. 449-469, Springer

Key words: failure; fissuring; marble; non-destructive analysis; restoration. "SEM and EDX examination of the weathered surfaces shows: ...; d) fungal growth (Lecanora dispersa and probably Lecanora campestris) along microfractures causes detachments of external surface flakes, affected by pitting (Figure 5). Pitting phenomenon is common in many marble monuments. This type of decay is usually attributed to the action of lichens and fungus, even if someone thinks that it is due to localised … Read more...

Zhang B.-W., Xu J.-L., Zhang H., Zhang Q., Lu J. & Wang J.-H. (2016): Structure elucidation of a polysaccharide from Umbilicaria esculenta and its immunostimulatory activity - PLoS ONE, 11(12): e0168472 [18 p.]

Umbilicaria esculenta has been used as a tonic food in China for several centuries owing to its pleasant flavor and health benefits. In this study, a water soluble polysaccharide, which we designated as UP2, with an average molecular weight of 3.33 × 105 Da, was isolated from U. esculenta cultivated in the Huangshan Mountain, by consecutive hot water extraction and anion-exchange chromatography. Gas chromatography analysis indicated that UP2 contained three kinds of monosaccharides, including mannose, … Read more...
