A simple and effective process for the recovery of intracellular poly(3-hydroxybutyrate) (PHB) from a halophilic bacterial strain - Salinivibrio sp. M318 was developed using a chemical digestion method.

Eleven Bacillus strains were isolated from foods and evaluated their probiotic potential and safety. Then study the effect of selected strains against pathogens, and on the population of pathogens in reconstituted skim milk (RSM).Seven strains from Bacillus sp.

Abstract
Background: Prefabricated orthotic devices are currently designed to fit a range of patients and therefore they do not provide individualized comfort and function. Custom-fit orthoses are superior to prefabricated orthotic devices from both of the[r]

Considering the high potential of phytase for use as feed supplement and its future prospective in animal feed and human nutrition, the present appraisal therefore aims at achieving the multifold improvement in the phytase production through sequential classical and statistical optimization strategy[r]

Chapter 4 - Supply and demand. After reading this chapter, you should be able to: State the law of demand and distinguish shifts in demand from movements along a demand curve, state the law of supply and distinguish shifts in supply from movements along a supply curve, explain how the law of demand[r]

The main objective of this study was to assess the environmental impact of the Nam Son landfill on the subsurface geological structure studied using 3D electrical imaging and self-potential investigations.

4.1 Introduction to synthesis and reduction methods for Petri nets
Petri net synthesis for analysis is the process of adding refinement to Petri net models in a manner in which certain properties like liveness and boundedness are preserved. The synthesis metho[r]

Little evidence exists regarding the optimal concentration of oxygen to use in the treatment of term neonates with spontaneous pneumothorax (SP). The practice of using high oxygen concentrations to promote “nitrogen washout” still exists at many centers.
