otitis externa--the clinical pattern in a tertiary institution in singapore.	otitis externa is a common condition in the tropics. most of the data related to the condition have arisen from western sources. locally, the aetiology and the pathogens identified have not been systematically studied. a prospective study involving 107 patients was conducted. otomycosis was frequently encountered. coagulase negative staphylococcus and aspergillus niger were the most common bacteria and fungus cultured respectively. gentamicin and polymyxin b were the most effective topical agent ...	1998	9663313
hemicellulase production by aspergillus niger dsm 26641 in hydrothermal palm oil empty fruit bunch hydrolysate and transcriptome analysis.	palm oil empty fruit bunches (efb) is an abundant and cheap lignocellulose material in southeast asia. its use as the sole medium for producing lignocellulose-hydrolyzing enzymes would increase its commercial value. a newly isolated aspergillus niger dsm 26641 was investigated for its capability of producing hemicellulases in efb hydrolysate obtained by treatment with pressurized hot water (1-20%, w/v) at 120-180°c in a 1 l parr reactor for 10-60 min. the optimal hydrolysate for the fungal growt ...	2014	24958131
isolation of filamentous fungi exhibiting high endoxylanase activity in lignocellulose hydrolysate.	for complete degradation of hemicellulose into its monomers from lignocellulose biomass, the synergistic action of a broad range of hydrolytic enzymes is needed. therefore, production of enzymes from their natural producer is desirable. to obtain a powerful β-1,4-endoxylanase producing fungus, 304 environmental samples were collected from various locations in singapore, leading to 603 isolates. among them, 71 exhibiting β-1,4-endoxylanase activity were identified belonging mainly to the genera o ...	2015	25432348
