No full textIdentification of volatile secondary metabolites from an endophytic microfungus aspergillus nomius KUB105
No full textMicrofungi are a highly diverse group of micro-organisms and important components of the ecosystem with great potential for diverse metabolite production. During a survey of microfungi on leaves in a National Park in Sarawak, an uncommon endophytic microfungus Aspergillus nomius was encountered. The metabolite production of this microfungus was investigated by growing it in a liquid basal medium for 2 weeks. Gas Chromatography - Mass Spectrometry (GC-MS) and Fourier Transform Infrared (FTIR) profiling of the secondary metabolites produced by this microfungus in the liquid medium revealed the presence of 46 different secondary metabolites. The metabolites include saturated hydrocarbons, alkyl halides, alcohols and an unsaturated hydrocarbon. Majority of the metabolites produced were saturated hydrocarbons. Tetracosane, Icosane and 10-Methylicosane were the most abundant metabolites identified while heptadecane and 2,4-dimethylundecane were the least abundant respectively. This study is the first GC-MS and FTIR report of secondary metabolites from A. nomius. The results from this study confirm the ability of microfungi to produce diverse metabolites, including saturated hydrocarbons
Grace under pressure: Leadership in emergency medicine
No full textPhysicians in general, including emergency physicians (EPs), are trained in the diagnostic, therapeutic, and administrative aspects of patient care but not so much in the theoretical and practical aspects of assuming and delivery of leadership. EPs are always taught to focus on their performance, to excel and achieve, to be accountable for their own clinical decisions, and to appreciate feedback and peer-to-peer review. Currently, if there are some semblances of formal or semi-formal leadership instruction, the organized theoretical curriculum often does not formally include very structured and planned departmental leadership and management elements. Leadership is a process for a person (≥the leader≥) to lead, influence, and engage a group or organization to accomplish their objectives and mission. To do this, the leader must understand a variety of issues of working, interacting, and integrating with people, the environment and both, the intrinsic and extrinsic factors, and elements that have an impact on the industry or area he/she is leading in. Leadership in emergency medicine (EM) is even more challenging, with its unique focus, issues, and trajectory, moving into the new century, with new considerations. No single strategy is sufficient to ace EM leadership and no single specific leadership model is complete. This paper shares some current views on medical/EM leadership. The author shares her views and some suggested proposals for more formal and structured leadership, implementation, and succession to help nurture and groom Eps who will become leaders in EM in the near future
Short communication: Microfungal diversity on leaves of Eusideroxylon zwageri, a threatened plant species in Sarawak, Northern Borneo
Get PDFAdebola AL, Sepiah M, Bolhassan MH, Wan Zamir M. 2015. Microfungal diversity on leaves of Eusideroxylon zwageri, a threatened plant species in Sarawak, Northern Borneo. Biodiversitas 16: 264-268. A survey of the microfungal communities on green leaves and leaf litters of an endangered plant species, Eusideroxylon zwageri Teijsm. & Binn. (belian) was carried out for the first time. A total of 200 leaf segments were plated on both water agar and malt extract agar. 74 fungal species were identified from both leaf types with more fungal taxa found on the green leaves, with a Shannon diversity index of 3.85 compared to that on litters, 2.63 and the similarity between the microfungal communities on both leaf types was low with a Bray-Curtis similarity index of 0.366. The most dominant species on both leaf types includes Aphanocladium areanarum, Trichoderma koningii, Nectria sp., Chalara pteridina, Hyphomycetes sp.3, hyaline Mycelia sterilia, Circinotrichum sp., Phoma sp., Acremonium macroclavatum, Chaetopsina sp., Physarum sp., Beltrania rhombica and Colletotrichum acutatum
Microfungi on Leaves of Licuala bidentata (Arecaceae) from Sarawak, Malaysia
Get PDFA microfungal survey was carried out on the living leaves and litters of Licuala bidentata in Kubah National Park in Sarawak, Malaysia. A total of 400 leaf segments (200 segments for each leaf type) were plated on two isolation media (water agar and malt extract agar) for endophytic and saprophytic fungal isolation. Forty-three microfungal species were obtained from both leaf types, 31 species identified from living leaves and 18 species from litters. Only six species were common to both leaf types, with 25 and 12 species exclusively identified from living leaves and litters, respectively. New records of fungi from this host plant and for the genus Licuala include Isthmotricladia laeensis, Chloridium sp., Mucor sp., Oidiodendron sp., Kinochaeta sp., Cryptophiale sp., Chrysosporium merdarium and Circinotrichum fertile. This study constitutes the first report on microfungal community on L. bidentata. Implications of this new report in comparison with the microfungal species on other plant species in the genus Licuala are discussed
Molecular Identification and Diversity of Pestalotiopsis, Neopestalotiopsis and Pseudopestalotiopsis Species from Four Host Plants in Sarawak, Borneo Island (Malaysia)
Get PDFUntil recently, Pestalotiopsis species have been identified based on host relationship and conidial dimensions. Pestalotiopsis species occur as endophytes, saprobes and also pathogens of many plant hosts. This study used molecular phylogenetic relationships based on ITS sequence data to identify Pestalotiopsis, Neopestalotiopsis and Pseudopestalotiopsis species in addition to their conidial pigmentation from four host plants namely Macaranga triloba, Macaranga sp., Shorea macrophylla and Syzygium sp. Based on the molecular phylogenetic analysis of 18 Pestalotiopsis-like isolates from the four different host plants, the isolates clustered separately into three clades corresponding to their conidial morphology and conidial median cell pigmentation as Neopestalotiopsis, Pestalotiopsis, and Pseudopestalotiopsis irrespective of their host plant association. Among the four host plants studied, S. macrophylla hosts the highest diversity of Pestalotiopsis-like species while Syzygium sp. had the lowest diversity. This is the first report on the molecular phylogenetics and diversity of Pestalotiopsis, Neopestalotiopsis and Pseudopestalotiopsis species from Sarawak, Malaysia in line with recent re-classification in the genus. New records of Pestalotiopsis-like species were also recorded on new host plants
