Influence of Zn2+ and Oxygen Supply on Malic Acid Production and Growth of Aspergillus oryzae

open access: yesBiotechnology and Bioengineering, EarlyView.
ABSTRACT Malic acid is a valuable platform chemical traditionally derived from fossil‐based resources. Microbial cultivation with Aspergillus oryzae offers a sustainable alternative based on renewable feedstocks. In this study, a well‐established minimal medium for malic acid production, commonly used in previous research to ensure reproducibility, was

Influence of plasma chemistry on oxygen triplets [PDF]

open access: yes, 2011
The plasma chemistry of fluorocarbon-oxygen-argon discharges and its influence on prominent oxygen triplets are studied. The oxygen 777 triplet is very important for the measurement of atomic oxygen in low pressure plasmas, since the 777.417 nm spectral

Spin‐State Engineering via Cr3+ Incorporation in Co3O4 Spinel for Efficient Bifunctional Oxygen Electrocatalysis

open access: yesCarbon Energy, EarlyView.
Cr doping causes distortion of the CoO6 octahedron, modifies the spin state of CoOh, and enhances the bifunctional catalytic activity. ABSTRACT The primary challenge in rechargeable Zn‐air batteries lies in developing a catalyst capable of simultaneously improving performance for oxygen reduction reaction (ORR) during discharge and oxygen evolution ...

Effect of snow cover on soil frost penetration

open access: yesContributions to Geophysics and Geodesy, 2017
Snow cover occurrence affects wintering and lives of organisms because it has a significant effect on soil frost penetration. An analysis of the dependence of soil frost penetration and snow depth between November and March was performed using data from ...

Using observation-level random effects to model overdispersion in count data in ecology and evolution [PDF]

open access: yes, 2014
Overdispersion is common in models of count data in ecology and evolutionary biology, and can occur due to missing covariates, non-independent (aggregated) data, or an excess frequency of zeroes (zero-inflation).

Alpine ungulates adjust diel activity to the natural return of wolves amid anthropogenic pressures

open access: yesEcography, EarlyView.
As wolves recolonise their historical range across Europe, ungulates face predation once more – but in landscapes profoundly altered by human activity. This shift raises crucial questions about their capacity to express adaptive antipredator behaviours.
