The inventor of 21 US patents and another 49 patents in 27 countries, Dr Lei was among the first to demonstrate that nutrients like phosphorus, calcium, zinc and iron become more bioavailable to animals when their feed is supplemented with phytase.

His lab developed a new generation of novel phytase enzymes from bacterial genes that are now used in 46 countries, according to Cornell CALS.

“Dr Lei’s pioneering and internationally recognized research program in animal nutrition resulted in inventions that directly impacted industry practice and benefited animal production and the environment,”​ said Alice Li, executive director of Cornell’s Center for Technology Licensing (CTL).

His dedication and contribution to animal nutrition and environmental sustainability are exceptional,” ​she added.

Waste to protein product

Dr Lei’s lab is currently looking to apply genomics, proteomics, and bioinformatics to reveal feather-degrading mechanisms of microbes and developing novel proteases for converting over 100 million tons of poultry feathers into feed protein supplements.

The team is also collaborating with the biofuel industry to evaluate defatted microalgal​​ biomass as a new source of feed protein for broiler chicks, layer hens, pigs, and pets. That work is funded by the US Department of Agriculture and the US Department of Energy.
