In a taxonomic survey on Cladosporium species in Iran, 35 specimens were collected from different substrates of various localities in Guilan (N. Iran) during 2011–12. Seven species viz. C. cladosporioides s. str., C. oxysporum, C. halotolerans, C. perangustum, C. pseudocladosporioides, C. sphaerospermum, and C. tenuissimum are identified and the latter five species are new records to Iran.

The potential of microalgae for steroid transformation has been studied less than other microorganisms. They have been applied for the years in the treatment of environmental pollutions and preparation of nutrients. At the first time, Abul-Hajj and Qian indicated the conversion of androstendione (AD) to testosterone with eleven different strains of microalgae. Previtera’s group showed the trans...

protective coatings that resist oxide scale growth and decrease chromium evaporation are necessary to makestainless steel interconnect materials for long-term durable operation of solid oxide fuel cells (sofcs). inthis study a layer of manganese was coated on the surface of aisi 441 ferritic stainless steel which is used insolid oxide fuel cells for interconnect applications. the oxidation beha...

in present study, the kinetic parameters of purified trypsin from pyloric caeca of common kilka (c.cultriventris caspia) were measured using the amidolytic (bapna) and esterolytic (tame) substrates. the results of the kinetic comparison between bapna and tame substrates showed that kinetic parameters including maximum velocity (vmax), catalytic constant (kcat) and catalytic efficiency (kcat/km)...

background and aims: the caspases are unique proteases that mediate the host cell apoptosis during viral infection. in this study, we identified the caspase cleavage motifs of h5n1 and h9n2 influenza viruses isolated during 1998-2012. materials and methods: amino acid sequences of the eleven proteins encoded by the viruses as the caspase substrates downloaded from ncbi. the caspase cleavage mot...
