RBD‐SD1 Nanoparticle Vaccines From DPP4‐Using Merbecoviruses Elicit a Cross‐Reactive Antibody Response but Limited Cross‐Protective Immunity

Biotechnology and Bioengineering, EarlyView.
SpyCatcher‐mi3 nanoparticles displaying RBD‐SD1 from MERS‐CoV, NL140422, and HKU4 elicited robust and cross‐reactive IgG responses in mice. Only MERS‐CoV RBD‐SD1 induced neutralizing antibodies against MERS‐CoV and protected human DPP4 mice from a MERS‐CoV challenge, indicating conserved serologic but limited cross‐neutralizing epitopes.

Engineered Bacterial Ligand From Streptococcus pneumoniae on Macroporous Resins for Selective Affinity Capture of Secretory IgA

Biotechnology and Bioengineering, EarlyView.
ABSTRACT Secretory immunoglobulin A (sIgA) is a promising emerging biopharmaceutical candidate, but it currently lacks a standardized platform for purification. To address this, a novel affinity chromatography resin was developed by immobilizing protein variants of the Streptococcus pneumoniae surface protein, SpsA, as an affinity ligand.

The Interplay of Dispersion and Thermal Shock in Pseudomonas Aeruginosa Biofilms

Biotechnology and Bioengineering, EarlyView.
ABSTRACT Pathological bacterial biofilms formed on medical implants pose a significant challenge in clinical settings due to their resistance to antibiotics and the host immune response. Eradication of these biofilms by thermal shock has gained increasing attention as a means of eliminating these infections.

Numerical and Experimental Assessment of Oxygen Distribution in a Perfusion Bioreactor to Mimic the Osteochondral Niche

Biotechnology and Bioengineering, EarlyView.
ABSTRACT Oxygen supply is a critical parameter in 3D cell cultivation using bioreactors. Since bioreactor designs often prioritise practical constraints, understanding the oxygen supply dynamics of the media is crucial for achieving either uniform or spatially controlled oxygen delivery.

Deciphering the catalytic and pharmacological mechanisms of Coptis chinensis herbzymes to renovate intestinal microenvironment for colitis alleviation

BMEMat, EarlyView.
The synthesized CCzymes possess both antioxidant enzyme activity and pharmacological properties inherent to Coptis chinensis. By their antioxidant enzyme activity, CCzymes can attenuate oxidative stress within the inflammatory region of ulcerative colitis (UC), while their pharmacological activity acts on macrophage polarization and the intestinal ...

Sulfate‐reducing bacteria [PDF]

Critical Reviews in Environmental Science and Technology, 1996
Abstract The corrosion of sewers and the control of odor are the major operational and maintenance problems in wastewater collection systems. The generation of hydrogen sulfide and subsequent sulfuric acid results from microbially mediated reactions, by sulfate‐reducing bacteria (SBR) and sulfide‐oxidizing bacteria.

Oxygen defense in sulfate-reducing bacteria

Journal of Biotechnology, 2006
Sulfate-reducing bacteria (SRB) are strict anaerobes that are often found in biotopes where oxic conditions can temporarily exist. The bacteria have developed several defense strategies in order to survive exposure to oxygen. These strategies includes peculiar behaviors in the presence of oxygen, like aggregation or aerotaxis, and enzymatic systems ...

Sulfate‐reducing bacteria in the periodontal pocket [PDF]

Oral Microbiology and Immunology, 1995
This report is the first to describe the occurrence of sulfate‐reducing bacteria in the human mouth. Samples of subgingival dental plaque were examined for the presence of sulfate‐reducing bacteria. Using enrichment cultures, sulfate‐reducing bacteria were detected in 25 (58%) of 43 individuals, and in 39 (48%) of the 82 samples.

Reduction of molybdate by sulfate-reducing bacteria

BioMetals, 2009
Molybdate is an essential trace element required by biological systems including the anaerobic sulfate-reducing bacteria (SRB); however, detrimental consequences may occur if molybdate is present in high concentrations in the environment. While molybdate is a structural analog of sulfate and inhibits sulfate respiration of SRB, little information is ...
