“…The genus comprises species that are saprobes, endophytes and pathogens. A few species have been documented as being etiologic agents in vertebrate hosts (David 1997;Bensch et al 2012Bensch et al , 2015Crous et al 2014). In this study, a new species of Cladosporium is described, with high bootstrap support in the phylogenetic analysis (Figure 7).…”

The authors established the taxonomic status of endophytic fungi associated with leaves of Pandanaceae collected from southern Thailand. Morphotypes were initially identified based on their characteristics in culture and species level identification was done based on both morphological characteristics and phylogenetic analyses of DNA sequence data. Twenty-two isolates from healthy leaves were categorised into eight morphotypes. Appropriate universal primers were used to amplify specific gene regions and phylogenetic analyses were performed to identify these endophytes and established relationships with extant fungi. The authors identified both ascomycete and basidiomycete species, including one new genus, seven new species and nine known species. Morphological descriptions, colour plates and phylogenies are given for each taxon. RESEARCH ARTICLESaowaluck Tibpromma et al. / MycoKeys 33: 25-67 (2018) 26

“…The six best PU-degrading strains we isolated were identified as members of the Cladosporium cladosporioides complex (26,34). The four different identified species were collected from diverse environments: garden soil, outdoor air, a PU-insulated wall in a cold room, and a dump site.…”

Polyurethane (PU) is widely used in many aspects of modern life because of its versatility and resistance. However, PU waste disposal generates large problems, since it is slowly degraded, there are limited recycling processes, and its destruction may generate toxic compounds. In this work, we isolated fungal strains able to grow in mineral medium with a polyester PU (PS-PU; Impranil DLN) or a polyether PU (PE-PU; Poly Lack) varnish as the only carbon source. Of the eight best Impranil-degrading strains, the six best degraders belonged to the Cladosporium cladosporioides complex, including the species C. pseudocladosporioides, C. tenuissimum, C. asperulatum, and C. montecillanum, and the two others were identified as Aspergillus fumigatus and Penicillium chrysogenum. The best Impranil degrader, C. pseudocladosporioides strain T1.PL.1, degraded up to 87% after 14 days of incubation. Fourier transform infrared (FTIR) spectroscopy analysis of Impranil degradation by this strain showed a loss of carbonyl groups (1,729 cm ؊1 ) and NOH bonds (1,540 and 1,261 cm ؊1 ), and gas chromatography-mass spectrometry (GC-MS) analysis showed a decrease in ester compounds and increase in alcohols and hexane diisocyanate, indicating the hydrolysis of ester and urethane bonds. Extracellular esterase and low urease, but not protease activities were detected at 7 and 14 days of culture in Impranil. The best eight Impranil-degrading fungi were also able to degrade solid foams of the highly recalcitrant PE-PU type to different extents, with the highest levels generating up to 65% of dry-weight losses not previously reported. Scanning electron microscopy (SEM) analysis of fungus-treated foams showed melted and thinner cell wall structures than the non-fungus-treated ones, demonstrating fungal biodegradative action on PE-PU. IMPORTANCEPolyurethane waste disposal has become a serious problem. In this work, fungal strains able to efficiently degrade different types of polyurethanes are reported, and their biodegradative activity was studied by different experimental approaches. Varnish biodegradation analyses showed that fungi were able to break down the polymer in some of their precursors, offering the possibility that they may be recovered and used for new polyurethane synthesis. Also, the levels of degradation of solid polyether polyurethane foams reported in this work have never been observed previously. Isolation of efficient polyurethane-degrading microorganisms and delving into the mechanisms they used to degrade the polymer provide the basis for the development of biotechnological processes for polyurethane biodegradation and recycling. P olyurethane (PU), one of the most versatile polymers invented by humans, is synthesized from a wide variety of precursors generating almost infinite types of materials, from elastomers and varnishes to highly resistant components, such as automotive parts, foams, semirigid plastics, and textile fibers. Due to their versatility, PUs are widely used in different human activities as a substit...

Biodiversity of fungi on Vitis vinifera L. revealed by traditional and high-resolution culture-independent approaches

This study is unique as it compares traditional and high-resolution culture-independent approaches using the same set of samples to study the saprotrophic fungi on Vitis vinifera. We identified the saprotrophic communities of table grape (Red Globe) and wine grape (Carbanate Gernischet) in China using both traditional and culture-independent techniques. The traditional approach used direct observations based on morphology, single spore isolation and phylogenetic analysis yielding 45 taxa which 19 were commonly detected in both cultivars. The same set of samples were then used for Illumina sequencing which analyzed ITS1 sequence data and detected 226 fungal OTUs, of which 176 and 189 belong to the cultivars Carbanate Gernischet and Red Globe, respectively. There were 139 OTUs shared between the two V. vinifera cultivars and 37 and 50 OTUs were specific to Carbanate Gernischet and Red Globe cultivars respectively. In the Carbanate Gernischet cultivar, Ascomycota accounted for 77% of the OTUs and in Red Globe, almost all sequenced were Ascomycota. The fungal taxa overlap at the genus and species level between the traditional and culture-independent approach was relatively low. In the traditional approach we were able to identify the taxa to species level, while in the culture-independent method we were frequently able to identify the taxa to family or genus level. This is remarkable as we used the same set of samples collected in China for both approaches. We recommend the use of traditional techniques to accurately identify taxa. Culture-independent method can be used to get a better understanding about the organisms that are present in a host in its natural environment. We identified primary and secondary plant pathogens and endophytes in the saprotrophic fungal communities, which support previous observations, that dead plant material in grape vineyards can be the primary sources of disease. Finally, based on present and previous findings, we provide a worldwide checklist of 905 fungal taxa on Vitis species, which includes their mode of life and distribution.
