Zygosaccharomyces bailii strain talf1 inulinases: a versatile tool for bioprocesses [PDF]

open access: yes, 2013
Fructans are one of the most abundant non-structural polysaccharides found in a wide range of plants. Inulin is a polydisperse fructan polymer composed by linear chains of b-2, 1-linked D-fructofuranose molecules terminated by a glucose residue through a

Molecular biological enhancement of coal biodesulfurization [PDF]

open access: yes, 1991
The objective of this project is to produce one or more microorganisms capable of removing the organic and inorganic sulfur in coal. The specific technical objectives of the project are to: clone and characterize the genes encoding the enzymes of the 4S'' pathway (sulfoxide/sulfone/sulfonate/sulfate) for release of organic sulfur from coal; return ...
