Taxonomic notes on Asplenium pseudoangustum (Aspleniaceae): a redescription based on spore morphology and distribution novelties [PDF]

open access: yesRodriguésia, 2023
Asplenium pseudoangustum is a poorly understood species known from the Peruvian Amazon forests. Due to morphological similarities with A. angustum and A. serratum, the position of A. pseudoangustum among the called A.

Morphological development of Aspergillus niger in submerged citric acid fermentation as a function of the spore inoculum level. Application of neural network and cluster analysis for characterization of mycelial morphology [PDF]

open access: yesMicrobial Cell Factories, 2006
Background Although the citric acid fermentation by Aspergillus niger is one of the most important industrial microbial processes and various aspects of the fermentation appear in a very large number of publications since the 1950s, the effect of the ...

Clostridium sordellii outer spore proteins maintain spore structural integrity and promote bacterial clearance from the gastrointestinal tract. [PDF]

open access: yesPLoS Pathogens, 2018
Bacterial spores play an important role in disease initiation, transmission and persistence. In some species, the exosporium forms the outermost structure of the spore and provides the first point of contact between the spore and the environment.

Palynomorphometry in ferns: Ctenitis (Dryopteridaceae), a case of study in the Southern Cone of America

open access: yesRodriguésia, 2023
The morphometric knowledge about the spores of the Ctenitis has not yet been deepened. Considering the folded spores of this genus which inhabit the Southern Cone of America the aims were to increase infrageneric knowledge, to evaluate the relationship ...

Investigating Physical and Chemical Interaction of Aspergillus terreus Spores for Changes in Morphology and Physiology [PDF]

open access: yes, 2020
It has been widely reported that in filamentous fungi, spore inoculum size affects culture morphology and secondary metabolite production. The reasons for this, however, have not been investigated thus far.

Structural Characterization of Clostridium sordellii Spores of Diverse Human, Animal, and Environmental Origin and Comparison to Clostridium difficile Spores

open access: yesmSphere, 2017
Clostridium sordellii is an often-lethal bacterium causing human and animal disease. Crucial to the infectious cycle of C. sordellii is its ability to produce spores, which can germinate into toxin-producing vegetative bacteria under favorable conditions.

The Cheilanthes hirta complex and allied species (Adiantaceae/Pteri­daceae) in southern Africa

open access: yesBothalia: African Biodiversity & Conservation, 1988
The very variable complex of plants until now ascribed to Cheilanthes hirta Swartz, together with some derived or allied species, is investigated. The type of the species as established by N. C. Anthony (1984), is accepted.
