A bacterial cutinase from Thermobifida fusca, named Tfu_0883, was genetically modified by site-directed mutagenesis to enhance its activity on poly(ethylene terephthalate) (PET). The new mutations tailored the catalytic site for PET, increasing the affinity of cutinase to this hydrophobic substrate and the ability to hydrolyze it. The mutation I218A was(More)
The use of probiotics such as Lactobacillus in animal feeds has gained popularity in recent years. In this study the 16S rRNA gene sequence of L. acidophilus in two commercial agents which have been used in animal feeds, LAB-MOS and Ghenisson 22, was determined. Phylogenetic tree analysis revealed that the two agents, strain MNFLM01 in LAB-MOS and strain(More)
