Scale‐up of Streptomyces species cultivations based on the morphological response to the energy dissipation rate

open access: yesAIChE Journal, EarlyView.
Abstract Filamentous microorganisms exhibit complex morphologies that influence product formation and are affected by various bioprocess parameters. Consistent morphology is therefore essential for comparable results during scale‐up. This study investigates the scale‐up of Streptomyces species (Streptomyces spp.) cultivations from shake flasks to ...

Use of Clotrimazole in Finfish Aquaculture: Mechanistic Insights, Limitations, and Future Directions for Antifungal Therapy

open access: yesAnimal Research and One Health, EarlyView.
This review critically evaluates clotrimazole as a potential antifungal for finfish aquaculture, highlighting strong mechanistic and in vitro efficacy against aquatic mycoses alongside major gaps in in vivo evidence, toxicokinetics, residue safety, and environmental risk, outlining priorities for responsible therapeutic development and regulatory ...

History of myxozoan character evolution on the basis of rDNA and EF-2 data

open access: yesBMC Evolutionary Biology, 2010
Background Phylogenetic relationships among myxosporeans based on ribosomal DNA data disagree with traditional taxonomic classification: a number of myxosporeans with very similar spore morphology are assigned to the same genera even though they are ...

Cryptosexuality and the genetic diversity paradox in coffee rust, Hemileia vastatrix. [PDF]

open access: yesPLoS ONE, 2011
BackgroundDespite the fact that coffee rust was first investigated scientifically more than a century ago, and that the disease is one of the major constraints to coffee production--constantly changing the socio-economic and historical landscape of the ...

Distribution, Abundance, Status, and Phytogeography of Log Ferns (Dryopteris: Woodsiaceae) in Arkansas [PDF]

open access: yes, 1988
A study of the distribution, abundance, status, and phytogeography of the six taxa of Log Ferns {Dryopteris: Woodsiaceae) that are known to occur in Arkansas was conducted from 1981 -1986. Five of these ferns are generally quite rare in Arkansas.

The extension of the taxon cycle model to island plants: insights from the Canarian vascular flora

open access: yesBiological Reviews, EarlyView.
ABSTRACT Taxon cycle models describe eco‐evolutionary patterns of lineage colonization, diversification, and decline across archipelagos, inferring an important role for competition amongst ecologically similar taxa in driving concurrent niche changes.

Spore Morphology and Systematics of the Genus Christensenia [PDF]

open access: yesAmerican Fern Journal, 1996
The spores of Christensenia are monolete, echinate, and superficially similar. How- ever, detailed SEM study reveals differences in spore shape, size, and exospore characters, such as spine distance, length, curvature, banding, apex morphology, and fusion. These differences are taxonomically significant and correlate completely with characters of gross
