There is growing scientific evidence supported by mechanistic and clinical studies that probiotics can provide health benefits. As probiotics are highly sensitive to many environmental factors, and because the propagation of many strains of intestinal origin is not straightforward, most commercial strains are selected on the basis of their technological(More)
To increase the yield of heterologous production of the class II bacteriocin DvnRV41 with Escherichia coli Origami (DE3) (pLysS/pCR03), induction of bacteriocin gene expression was optimized by varying the inducer isopropyl β-d-thiogalactopyranoside (IPTG) concentration (0–2 mM), and controlled batch and fed-batch cultures were tested on a 2-L scale.

Silk fibroin was evaluated as a new matrix for immobilized cell fermentation. Silk fibroin was extracted from Bombyx mori cocoon, purified, concentrated in polyethylene glycol solution and diluted to 3 wt% with distilled water. This fibroin solution was used to encapsulate sensitive cells of the probiotic strain, Bifidobacterium longum ATCC 15707. Polymer(More)
This paper presents a wavelet transform (WT) and artificial neural network (ANN) based algorithm for estimating fault location on transmission lines. The algorithm is developed as a one-end frequency based technique and used both voltage and current effect resulting from remote end of the power system. Fault simulation is carry out in Alternative Transient(More)
