Microbial production of textile grade pigments

African Journal of Microbiology Research, 2017
Biological pigments or biochromes are substances produced by living organisms and have a color  resulting from selective color absorption. A total of 37 isolates of Actinomycetes and 2 bacteria were isolated from 26 different soil samples collected from different habitats of Kerala. The isolates were screened for pigment production.

Sex‐Specific Regulation of Glycemic Homeostasis by Theabrownin from Pu‐erh Tea

Advanced Science, EarlyView.
Pu‐erh tea's key component, theabrownin (TB), lowers blood glucose in a sex‐specific manner. In females, estrogen boosts intestinal MUC2 production, which dramatically enhances TB's ability to inhibit the carbohydrate‐digesting enzyme α‐glucosidase.
