Abstract:

Changes to crystallisation conditions can critically affect important physical properties of materials, which can in tum affect the sustainability of consistent product quality that is pivotal to industrial manufacturing. The following studies demonstrate how crystallisation processes, and the consequent quality of the crystals produced, can be easily manipulated by varying the solution mixing regimes and initial relative supersaturation. Most importantly, emphasis was given to changes to the material's physical properties induced by the presence of impurities in solution. To this effect, alph

This is the first demonstration of stability and activity of an ammonia-lyase in organic solvents.

Nylon membrane artificial cells were prepared to produce essential amino acids.

Kinetic analysis showed that diffusion restriction is negligble when batch and packed-bed column bioreactors were used. The limiting step controlling the rate was the chemical reaction. The effect of backmixing on degree of conversion was insignificant. Ammonia conversion v

Phenylketonuria and hyperphenylalanemia are autosomal recessive inborn errors of phenylalanine metabolism that are caused by mutations in the phenylalanine hydroxylase gene.

碩士<br>逢甲大學<br>化學工程研究所<br>85<br>The objective of this research is to investigate the effect of emulsion liquid membrane ( ELM ) encapsulation system on the activity of L-phenylalanine-produced enzymes. Two kinds of enzymes , aromatic amino acid amino transferase ( AAT ) and L-phenylalanine ammonia-lyase(PAL)，are adopted in the study . The enzymes o f AAT and PAL are biologically synthesized form fermentation of E.coli , genetically - modified E.coli (VJS632/ pTYR100,VJS676/pASP400 )

Abstract:

Dissertação de mestrado em Biotecnologia<br>The biotechnological production of flavours and fragrances has become increasingly attractive due to its acceptability by the consumers since they are considered “natural” compounds. 2-Phenylethanol (2-PE) is an aromatic alcohol with delicate fragrance of rose petals, widely used in perfumes, cosmetics, foods, beverages, and pharmaceutical industries. The yeast Yarrowia can produce 2-PE through the L-Phenylalanine (L-Phe) biotransformation. However, it is poorly explored in this field, despite its interesting characteristics for this process, such as

碩士<br>國立中央大學<br>化學工程與材料工程學系<br>107<br>2-Phenylethanol (PEA) is one of the important flavor and fragrance compound in the world with a rose-like aroma. In addition, it is widely used in the cosmetics, perfume, and food industries. PEA can be produced from L-phenylalanine (L-Phe) through Ehrlich pathway using yeasts. In the fermentation process, the growth of yeast will be limited by product inhibition, cultivation temperature will also has a strong connection with microbial growth and fermentation behavior. In this work, we have explored the effects of temperature on bioconversion of L-Phe in
