To make yellowcake, first uranium ore must be mined, then milled and processed in acid. But often mined ore is of a very low concentration and extraction involves expensive and hazardous processes such as roasting and smelting.
Using biotechnology -- or a technique known as "bioleaching" -- a bacteria introduced to the ore, eats on iron sulphur and produces sulphuric acid which in turn dissolves the ore and separates the uranium.
This then makes yellowcake production easier.
