Ribosomally synthesized bacteriocins of lactic acid bacteria: Simplicity yet having wide potentials - A review.

Bacteriocins are ribosomally made bacterial peptides that have outstanding contributions in the field of food industry, as biopreservatives, and promising potentials in the medical field for improving human and animal health. Bacteriocins have many advantages over antibiotics such as being primary metabolites with relatively simpler biosynthetic mechanisms, which made their bioengineering for activity or specificity improving purposes much easier. Also, bacteriocins are degraded by proteolytic enzymes and do not stay in environment, which reduce chances of developing resistance.

Structure analysis and antioxidant activity of polysaccharide-iron (III) from Cordyceps militaris mycelia.

Iron-enriched Cordyceps militaris was obtained by adding FeSO solution to the mycelia for biotransformation. The polysaccharide-iron (III) was extracted by water extraction and alcohol precipitation. High performance liquid chromatography showed that the crude polysaccharide-iron (III) had three components.
