NCL scientists to boost mineral bioavailability


Scientists at National Chemical Laboratory (NCL), Pune, have identified a yeast strain that can improve absorption of phosphorus and make other vital minerals bioavailable. Phosphorus deficiency can lead to several health complications. Many a times we face this deficiency depsite consuming phosphorus-rich food. This is because inability of human body to absorb it.


NCL researchers have identified the yeast strain called Saccharomyces cerevisiae (NCIM 3662) which can effectively dephytinize the phytate to free phosphorus and also possess the probiotic properties. The team has isolated the particualr yeast strain from rhizosphere soil and screened its phytase activity.


The probiotic property of the isolated yeast strain was demonstrated by its capability to withstand harsh gastrointestinal tract environment. A detailed study was performed on its capacity to tolerate artificial gastric acid conditions, hydrophobicity, autoaggregation and coaggregation ability, bile salt hydrolase (BSH) activity and capability to survive in low oxygen conditions of gut. It has all necessary attributes of a probiotic.
