Digital Analysis of Mycelium Growth and Mycelium Density In Vitro of Pleurotus ostreatus with Submerged Fermentation as Substrate Treatment [PDF]

open access: yesMycobiology
Edible mushroom cultivation often involves sterilizing the substrate, or a similar heat process like pasteurization, to facilitate mycelial colonization. Chemical treatments are an alternative approach that is also employed in some regions.

Evidence of rare occurrences of the Phoenix effect in the Hawaiian corals Porites compressa and Montipora capitata following mortality induced by a marine heatwave [PDF]

open access: yesPeerJ
Coral bleaching is a common stress response to extreme temperatures experienced during marine heatwaves. Bleached corals are left vulnerable without the nutritional support of their algal symbionts, and can often suffer partial or complete mortality ...

The extracellular matrix protects Bacillus subtilis colonies from Pseudomonas invasion and modulates plant co-colonization [PDF]

open access: goldNature Communications, 2019
Pseudomonas and Bacillus can promote plant growth but their mutual interactions are unclear. Here, the authors show that the extracellular matrix protects Bacillus colonies from infiltration by Pseudomonas cells, while the Pseudomonas type VI secretion ...

Phenotypic Heterogeneity and the Evolution of Bacterial Life Cycles. [PDF]

open access: yesPLoS Computational Biology, 2016
Most bacteria live in colonies, where they often express different cell types. The ecological significance of these cell types and their evolutionary origin are often unknown. Here, we study the evolution of cell differentiation in the context of surface

Description of the Colonization of a Gnotobiotic Tomato Rhizosphere by Pseudomonas fluorescens Biocontrol Strain WCS365, Using Scanning Electron Microscopy

open access: yesMolecular Plant-Microbe Interactions, 1997
To study colonization of the tomato root system, we previously have described a gnotobiotic quartz sand system, in which seedlings inoculated with one or two bacterial strains were allowed to grow.
