l-Methionine γ-lyase (MGL), a pyridoxal 5'-phosphate-dependent enzyme, possesses anti-tumor activity. However, the low activity of MGL blocks the anti-tumor effect. This study describes an efficient production process for the recombinant MGL (rMGL) from Idiomarina constructed using the overexpression plasmid in Escherichia coli BL21 (DE3), purification, and large-scale production. The enzyme pr...

Although, several pineapple micropropagation protocols have already been published, significant improvement could be achieved, if the stages of in vitro culture were better defined. Our work concerned several experiments aiming at the mass production of high quality plantlets. Tissue culture experiments were therefore conducted to develop rapid multiplication procedures for Ananas comosus L. (M...

Date palm (Phoenix dactylifera L.) is propagated traditionally through offshoots or suckers, which usually appear at or below the ground level surrounding the stem base. However, there are many problems associated with this system. Offshoots are produced in limited number and vegetative propagation through them is slow, laborious, time consuming and expensive. The present study was conducted to...
