The effects of the amino acids on the growth of Lactobacillus acidophilus were investigated in this paper.In addition,the effects of 16 kinds of amino acids on enriching and anti-freezing ability of L.acidophilus were studied by single factor test.The results showed that the L-glutamic acid,L-arginine,L-leucine,L-lysine,L-methionine,L-proline,L-phenylalanine and L-threonine can promote the growth of L.acidophilus.L-alanine,L-isoleucine,L-cysteine,L-serine,L-phenylalanine,L-aspartic acid,glycine and L-proline can increase the anti-freezing ability of L.acidophilus.The study showed that multi-amino acid,which was composed of 0.03g/L L-isoleucine,0.03g/L L-cysteine,0.03g/L L-aspartate,0.03g/L L-serine and 0.03g/L glycine or composed of 0.03g/L L-cysteine,0.03g/L L-aspartate,0.03g/L L-alanine and 0.03g/L glycine,added to culture medium can increase the survival rate of L.acidophilus powder up to 95%,while the control sample was only 42.95%.

Electromagnetic pump modeling and simulation based on pseudo-bond graph methods

Based on the modeling and simulation software 20-sim developed by university of Twente(the Netherlands),the electromagnetic pump is studied by using bond graph methods which could simulate and realize the interaction process of the electrical domain,the magnetic domain and the hydraulic domain.The inputs and outputs situation of electromagnetic pump are also simulated and analyzed.According to the conditions of the heat generation in the pump's chamber during the working process,the pseudo-bond graph methods are used for simulating the thermal system of the pump.The thermodynamic properties and dynamic features of this system are revealed comprehensively.To explain the reasons for the ripple generation in the input part of the pump,the parameters are adjusted to eliminate the influence of ripples.The simulation results show the ideal effect during the design period when using 20-sim and pseudo-bond graph methods.
