“…This intra-species β-tubulin variation is in contrast with species in subgenus Penicillium, where various species share the same tubulin sequence . The large variability among P. glabrum isolates originating from cork is also observed using microsatellite primers (Basílio et al 2006). Our analysis show that P. flavidorsum, P. spinuloramigenum, P. terlikowskii, P. trzebinskii and P. oledzskii are synonyms of P. glabrum.…”

A mycological survey of fungi, present in several stages of the manufacturing of cork discs for champagne stoppers in Portugal, was made. Sixty-nine strains belonging to the Glabra series of the genus Penicillium were isolated and subsequently grouped according to their partial β-tubulin gene sequences. Six groups with different partial β-tubulin gene sequences were observed, and a selection of isolates of each group was made. These selected isolates and various related ex-type strains were subjected to a taxonomical study using a polyphasic approach. This approach included analysis of macro-and microscopic features, the comparison of extrolite profiles and sequencing a part of the β-tubulin and calmodulin gene. The six β-tubulin types were reduced to three different species. One group of isolates was centred on the ex-type strain of P. glabrum, a second group accommodated the type strain of P. spinulosum and a third group contained isolates which were unique in their β-tubulin and calmodulin sequences, extrolite profiles and growth characteristics. This group of isolates is described as the new species Penicillium subericola. The type strain of P. subericola CBS 125096 T was isolated from Portuguese raw cork, but additional isolates were found from soil, air and lumen.

“…This type of industry has already been associated with exposure to several fungal species, most commonly with the Penicillium glabrum complex and Chrysonilia sitophila (5)(6)(7)(8)(9)(10)(11)(12)(13). The presence of the P. glabrum complex in this industry involves the risk of respiratory diseases such as suberosis, a type of hypersensitivity pneumonitis that is one of the most prevalent diseases among cork workers (8)(9)(10)(11)(12)(13)(14)(15).…”

Cork oak is the second most dominant forest species in Portugal and makes this country the world leader in cork export. Occupational exposure to Chrysonilia sitophila and the Penicillium glabrum complex in cork industry is common, and the latter fungus is associated with suberosis. However, as conventional methods seem to underestimate its presence in occupational environments, the aim of our study was to see whether information obtained by polymerase chain reaction (PCR), a molecular-based method, can complement conventional findings and give a better insight into occupational exposure of cork industry workers. We assessed fungal contamination with the P. glabrum complex in three cork manufacturing plants in the outskirts of Lisbon using both conventional and molecular methods. Conventional culturing failed to detect the fungus at six sampling sites in which PCR did detect it. This confirms our assumption that the use of complementing methods can provide information for a more accurate assessment of occupational exposure to the P. glabrum complex in cork industry.

“…The species diversity amongst the cork-colonising fungal communities is largely inXuenced by the origin of the cork, explaining some of the discrepancy found in the strains reported by diVerent authors [1,2,8,11,17,[26][27][28][29]. In this study, the fungal strains used were isolated from cork bark samples, which were collected during plank preparation for the manufacture of stoppers.…”

Pentachlorophenol (PCP) bioremediation by the fungal strains amongst the cork-colonising community has not yet been analysed. In this paper, the co-and direct metabolism of PCP by each of the 17 fungal species selected from this community were studied. Using hierarchical data analysis, the isolates were ranked by their PCP bioremediation potential. Fifteen isolates were able to degrade PCP under co-metabolic conditions, and surprisingly Chrysonilia sitophila, Trichoderma longibrachiatum, Mucor plumbeus, Penicillium janczewskii and P. glandicola were able to directly metabolise PCP, leading to its complete depletion from media. PCP degradation intermediates are preliminarily discussed. Data emphasise the signiWcance of these fungi to have an interesting potential to be used in PCP bioremediation processes.
