Sulfur is one of the six elements required during the early stages of the evolution of life, and enzymes involved in sulfur transfer and oxidation are increasingly being recognized as potential drug targets for antimicrobials as well as for therapies for cancer, neurodegenerative and inflammatory diseases. Bacteria are able to...
Although the biology of Bradyrhizobium has been studied for almost
one hundred years, virtually nothing is known about the ecology and genetic
variation in natural soil populations of this genus. The majority of
information has been obtained from studies of one species, Bradyrhizobium
japonicum, and the diversity within soil populations...
Optimization programming techniques were applied to
develop the least cost formulations for Pacific whiting
surimi-based seafood (PWSBS). To develop the quality
constraint functions, texture and color of whiting surimi
gels were determined by torsion test and colorimeter,
respectively. Whiting surimi gels were produced by heating
at 90°C for 15 min....
Radish anthocyanin extract has potential as a natural colorant because of
its pigment stability and attractive red hue. Presence of undesirable aroma
compounds could limit its applications in foods. The pungent principle of
radish, 4-methylthio-3-butenyl isothiocyanate (MTBI), is produced
enzymatically upon cell injury from its glucosinolate precursor, 4-methylthio-3-butenyl glucosinolate (MTBG),...
The evolutionary relationship between Frankia and actinorhizal plants was evaluated
by reconstructing molecular phylogenetic trees from nifH, 16S rDNA, and rbcL
nucleotide sequences. Subgroupings in Frankia phylogenetic trees reconstructed from
nifH and from 16S rDNA sequences were consistent in terms of plant origins of Frankia
strains. Although the branching order...
Cometabolic biodegradation processes are potentially useful for the
bioremediation of hazardous waste sites. In this study the potential application of phenol-oxidizing
and nitrifying bacteria as "priming biocatalysts" was examined in the
degradation of polycyclic aromatic hydrocarbons (PAHs), aryl ethers, and aromatic
ethers. We observed that a phenol-oxidizing Pseudomonas strain cometabolically...
The vascular system transports components essential to the survival of the individual and acts as a barrier to substances that may injure the organism. Atherosclerosis is a dynamic, lesion producing disease of the arterial system that compromises the functioning of the organ by occlusive and thrombogenic processes. This investigation was...
