Development of an ethylometer with an MQ-3 sensor for measuring ethanol in soybean seeds
Revista Brasileira de Engenharia Agrícola e Ambiental, 2022 In the seed production sector, it is essential to use fast and practical equipment to help decision-making processes. Thus, the use of sensors that can capture information to assist in agriculture has contributed significantly to soybean cultivation ...

Molecular Microbiology, EarlyView.The periplasmic multicopper oxidase CueO oxidizes cuprous ions (Cu+) to cupric ions (Cu2+), a well‐known process typically coupled with oxygen reduction. In this study, we report unexpected anaerobic phenotypes associated with CueO, suggesting that it may use an alternative electron acceptor in the absence of oxygen.

Incorporation in vitro of labeled amino acids into bone marrow cell proteins [PDF]
, 1950 Nearly all experiments on the incorporation of labeled amino acids into tissue proteins in vitro have been done on tissues whose cell structure has been partially or completely disintegrated, e.g. tissue slices, segments, or homogenates.

The Role of the [2Fe‐2S] Cluster of Escherichia coli IscR in Responding to Redox‐Cycling Agents
Molecular Microbiology, EarlyView.Redox cycling agents like phenazine methosulfate (PMS) are known for upsetting cellular redox balance. Here we describe how PMS leads to upregulation of the ISC and SUF Fe‐S cluster biogenesis pathways in Escherichia coli when PMS oxidizes the [2Fe‐2S]1+ cluster of the transcription factor IscR, thereby derepressing the operon encoding ISC and, when a ...

Exploring the Molecular Machinery of Denitrification in Haloferax mediterranei Through Proteomics
Frontiers in Microbiology, 2020 Many proteins and enzymes involved in denitrification in haloarchaea can be inferred to be located between the cytoplasmic membrane and the S-layer, based on the presence of a Tat signal sequence and the orientation of the active site that some of these ...
