Article Synopsis
- - Levels of progesterone increase after ovulation and are vital for supporting pregnancy, but gut microbiota can influence these levels by affecting the hormone's recycling in the liver and gut.
- - A specific gut bacterium plays a key role in metabolizing progesterone into a neurosteroid, which does not have progestogenic activity; researchers identified the enzyme responsible for this conversion.
- - In experiments with female mice, certain antibiotics helped restore progesterone levels, and prolonged antibiotic use disrupted ovarian follicle development, suggesting a link between gut bacteria and progesterone resistance in women.
The disposal of soybean pulp (okara) (∼14 M tons annually) represents a global concern. α-ketoisocaproate (KIC) is an intrinsic l-leucine metabolite boosting mammalian muscle growth and has great potential in animal husbandry. However, the use of pure l-leucine (5000 USD/kg) for KIC (22 USD/kg) bioproduction is cost-prohibitive in practice, while okara rich in l-leucine (10%) could serve as an economical alternative.

The genome provides further insight into the adaptation of bacteria to the toxic environment from where it was isolated.

In this study, a mercury-reducing bacterium, Photobacterium spp. strain MELD1, with an MIC of 33 mg x kg(-1) mercury was isolated from a severely mercury and dioxin contaminated rhizosphere soil of reed (Phragmites australis).
