L-Phenylalanine ammonia-lyase (PAL, EC 4.3.1.25) from Rhodosporidium toruloides was utilized to remove L-phenylalanine (L-Phe) from different commercial protein hydrolysates. A casein acid hydrolysate (CAH, L-Phe ~2.28 %) was employed as a ...
The modeling of ethanol production by Kluyveromyces marxianus using whey as substrate in continuous A-Stat bioreactors [0.03%]
利用连续A-Stat生物反应器以乳清为底物用马克斯克鲁维酵母进行乙醇生产的建模工作

We investigated the kinetics of whey bioconversion into ethanol by Kluyveromyces marxianus in continuous bioreactors using the "accelerostat technique" (A-stat). Cultivations using free and Ca-alginate immobilized cells were evaluated using...
Functional manipulations of the tetramycin positive regulatory gene ttmRIV to enhance the production of tetramycin A and nystatin A1 in Streptomyces ahygroscopicus [0.03%]
四環素正调控基因ttmRIV的功能研究及功能敲除菌株产生四環素A和納斯他丁A1的高产 mutants 构建

Hao Cui et al.
A putative regulatory gene ttmRIV located in the tetramycin biosynthetic gene cluster was found in Streptomyces ahygroscopicus. In-frame deletion of ttmRIV led to abolishment of tetramycin and significant enhancement of nystatin A1, whose p...
Biosynthetic enhancement of single-stage Poly(3-hydroxybutyrate-co-4-hydroxybutyrate) production by manipulating the substrate mixtures [0.03%]
通过操纵底物混合物提高单阶段聚（3-羟基丁酸-co-4-羟基丁酸）生物合成的增强效果

Kai-Hee Huong et al.
Two-stage fermentation was normally employed to achieve a high poly(3-hydroxybutyrate-co-4-hydroxybutyrate) [P(3HB-co-4HB)] productivity with higher 4HB molar fraction. Here, we demonstrated single-stage fermentation method which is more in...
Batch production of coenzyme Q10 by recombinant Escherichia coli containing the decaprenyl diphosphate synthase gene from Sphingomonas baekryungensis [0.03%]

Cell migration is a fundamental step for embryonic development, wound repair, immune responses, and tumor cell invasion and metastasis. Extensive studies have attempted to reveal the molecular mechanisms behind cell migration; however, they...
Enhancing xylanase production in the thermophilic fungus Myceliophthora thermophila by homologous overexpression of Mtxyr1 [0.03%]
通过Mtxyr1的同源过表达提高高温丝状真菌Myceliophthora thermophila中木聚糖酶的产量

Juan Wang et al.
The xylanase regulator 1 protein in Myceliophthora thermophila ATCC42464 (MtXyr1) is 60 % homologous with that of Trichoderma reesei. However, MtXyr1's regulatory role on cellulolytic and xylanolytic genes in M. thermophila is unknown. Here...
Scalable temperature induced stress for the large-scale production of functionalized Bifidobacteria [0.03%]
