Endophytes from the pharmaceutical plant, Annona squamosa: isolation, bioactivity, identification and diversity of its polyketide synthase gene

et al. 2010

Endophytic fungi were isolated from the pharmaceutical plant Annona squamosa during different seasons and 131 strains were isolated. Fermentation extracts of each strain was assayed using six different screening programs for bioactive compounds. Sixty-three of the strains producing bioactive compounds were identified by ITS rDNA sequence data. The diversity of the polyketide synthase (PKS) genes of these 63 strains was investigated using three pairs of primers, LC1-LC2c, LC3-LC5c and KS3-KS4c. Phylogenetic analysis showed that these fungi are distributed in 10 orders, in 19 genera, mostly in the orders Diapothales and Hypocreales. The groups with the highest bioactivity were from Diapothales, Clavicipitales and Xylariales. The relationship between the taxa producing bioactive compounds and the PKS genes indicates that 11 out of the 63 strains analysed contained all three KS domains. Eight of these belonged to the order Diapothales. Twenty mostly hypocrealean and phyllachoralean strains lacked a single KS domain in all three pairs of primers amplified. Two important conclusions can be drawn from this investigation. The endophytic fungi of A. squamosa contain a community with a high degree of bioactivity: Secondly, compared with other fungi, those taxa from the order Diapothales have a rich species diversity and rich PKS gene domains. These findings suggest that they have a high potential as producers of natural bioactive compounds.Ministry of Science and Technology [2007DFA30970]; National High Technology Research and Development Program of China [2007AA091503

“…A revision of the data, however, is difficult, because often voucher specimens are not available, fragmentary, or not cited at all. This is a general problem of taxonomic revisions of fungi, approximately 25% of the species of fungi recorded worldwide are known from a single, often fragmentary collection with an inadequate description (Cannon and Hawksworth 1995). With these facts in mind, the importance of intensive field work in the tropics as well as the preparation of good herbarium specimens, good descriptions, and informative illustrations seem to be more important than the revision of incomplete data published in the past.…”

Inventoring the fungi of Panama

Records of fungi in Panama scattered in literature are presented in a preliminary annotated checklist which is published in Panama. It includes 1807 species and subspecific taxa in 646 genera. The data allow to trace more than 100 years of history of mycology in Panama, presented here for the first time. The species richness is analyzed numerically with respect to the systematic position of the species and their ecology. Considering the numbers of records for different regions of Panama, a comparison with numbers of species published for some other neotropical countries, as well as recent experience collecting fungi in Panama, the incompleteness of the checklist is evident. Values of relative species richness of different systematic groups in Panama compared to values of the same groups as known worldwide, show that our knowledge is fragmentary in Panama especially for Agaricales, Uredinales, and some groups of microfungi. We are still in the pioneer phase of mycological investigation in Panama.

The present study was conducted to study the level of yeast contamination in indoor public swimming pools in Duhok city. A total of 230 samples (50 water sample) were taken from swimming pool water and (180 swab samples) were taken from walls, flour of bathrooms, dressing rooms and flour around the pool in five indoor public swimming pools from September 2014 to February 2015. All samples were examined for the presence of yeasts using three culture media (Potato Dextrose Agar, Malt Extract Agar and Sabouraud's Dextrose Agar). The highest number of Yeast genera was in November (6) followed by October (5), December and January (4) while the lowest number was in September (3). Eleven (11) isolates yeasts were selected randomly for in vitro sensitivity to the disinfectant agents {Chlorine, Chloroxylenol and Hydrogen peroxide (H2O2)}. All tested isolates were highly sensitive to chlorine, Chloroxylenol and H2O2. The MIC value of chlorine for most of them was 0.01 % and for Chloroxylenol was 0.1 % except Candida tropicalis and C. glabrata. Regarding the effect of H2O2 the MIC value ranged from 0.1% -12.8 %.
