Aspergillus sakultaensis, a new species in section Flavipedes isolated from Sohag Governorate, Egypt (original) (raw)

Aspergillus sakultaensis a new species in section Flavipedes

During the routine sampling from Atawayel canal at Atawayel village, Sakulta city, Sohag Governorate, Egypt and isolation of fungi from these water samples, an interesting isolate of Aspergillus was discovered. The phenotypic characteristics of the isolate revealed its strong relationship to Aspergillus section Flavipedes. Sequencing of the Internal Transcribed Spacer (ITS) gene demonstrated that the isolate is a new species belonging to section Flavipedes. The new taxon morphological characters exhibited a huge differentiation between other species in brightly yellow mycelium color on MEA and CYA at 25 °C and on MEA, CYA, Cz and CREA at 30 °C, conidiophore length (up to 3 mm), accessory conidia absence and hull cells shape. The new strain was described and illustrated as A. sakultaensis. A pure culture of the new taxon was deposited in the culture collection of the Assiut University Mycological Centre as AUMC13885, uploaded in MycoBank MB831480 and the ITS sequence was uploaded to GenBank as MK391495.

Revision of Aspergillus section Flavipedes: seven new species and proposal of section Jani sect. nov

Mycologia

Aspergillus section Flavipedes contains species found worldwide in soils and rhizospheres, indoor and cave environments, as endophytes, food contaminants and occasionally as human pathogens. They produce many extensively studied bioactive secondary metabolites and biotechnologically relevant enzymes. The taxa were revised based on phylogenetic analysis of sequences from four loci (β-tubulin, calmodulin, RPB2, ITS rDNA), two PCR fingerprinting methods, micro- and macromorphology and physiology. Section Flavipedes includes three known and seven new species: A. ardalensis, A. frequens, A. luppii, A. mangaliensis, A. movilensis, A. polyporicola and A. spelaeus. The name A. neoflavipes was proposed for Fennellia flavipes a distinct species from its supposed asexual state A. flavipes. Aspergillus iizukae, A. frequens and A. mangaliensis are the most common and widely distributed species, whereas A. flavipes s. str. is rare. A dichotomous key based on the combination of morphology and phys...
