Continuous Anaerobiosis for Cultivation of Spirochetes.
SummaryApparatus and procedures have been developed for bacteriological work based on a vacuum-tight glove box with lock, in which an anaerobic working atmosphere has been maintained by evacuation, followed by removal of residual and diffusing oxygen with hydrogen and a catalyst that does not require pre-heating.

A comprehensive study on ferredoxin isoforms in the cyanobacterium Synechocystis sp. PCC 6803
Ferredoxins are small FeS cluster‐containing proteins that play a central role in distributing electrons within the cell. The cyanobacterium Synechocystis sp. PCC 6803 contains several ferredoxin isoforms and their biophysical properties (UV/Vis and EPR spectra, Em potential), expression patterns, and interactions with the electron donors photosystem I

UbiB proteins mediate an ATP‐dependent decarboxylation step in bacterial ubiquinone biosynthesis
UbiB proteins are atypical protein kinase‐like enzymes essential for ubiquinone biosynthesis. Here, we demonstrate that bacterial UbiB proteins catalyze the O2‐dependent decarboxylation of ubiquinone precursors, a process linked to their ATPase activity.

EFFECTS OF ANAEROBIOSIS ON THE RATES OF MULTIPLICATION OF MAMMALIAN CELLS CULTURED IN VITRO
To test the effects of anaerobiosis on the rate of multiplication and carbohydrate metabolism of mammalian cells in vitro, cultures of a 'permanent' line, Earle's L strain cells, and of freshly explanted embryonic mouse cells were propagated in the ...

Effect of aero-/anaerobiosis on decarboxylase activity of selected lactic acid bacteria [PDF]
Biogenic amines are undesirable compounds produced in foods mainly through bacterial decarboxylase activity. The aim of this study was to investigate some environmental conditions (particularly aero/anaerobiosis, sodium chloride concentration (0–2% w/w),

Managed Aquifer Recharge Operations and Design under Hydrologic Uncertainty
Integrated hydrologic modeling uses dual ensembles of MAR operations and IES‐derived parameters to evaluate mounding, inundation, and transport risks under climate extremes. Exceedance‐probability metrics quantify environmental risks across the MAR impact zone, showing drain‐controlled mound limits, recovery effects, and pathways to interdunal and ...

Exploring the Molecular Machinery of Denitrification in Haloferax mediterranei Through Proteomics
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 ...

Effect of Anaerobiosis on Antimicrobial Susceptibility of Staphylococci [PDF]
The minimum inhibitory concentration (MIC) of 12 antibiotics was determined for four strains of staphylococci (representing the three major species) under aerobic and anaerobic conditions by using the broth dilution method. Nine of the antibiotics showed no significant difference between aerobic and anaerobic MIC for any of the four cultures ...

The Many Facets of Hypoxia in Plants
Plants are aerobic organisms that require oxygen for their respiration. Hypoxia arises due to the insufficient availability of oxygen, and is sensed by plants, which adapt their growth and metabolism accordingly.

ABSTRACT Doubled haploid technology accelerates the development of fully homozygous maize lines compared with conventional selfing. However, specific protocols for supersweet corn (Zea mays L. var. saccharata), particularly regarding immersion time in antimitotic solutions and temperature during chromosome doubling, remain poorly defined.
