Enhancement of the activated sludge process by activated carbon produced from surplus biological sludge
Biotechnology Letters - Tập 24 - Trang 163-168 - 2002
Surplus biological sludge from wastewater treatment operations was converted into activated carbon and then added to the aerated vessel of an activated sludge process treating phenol and glucose. The addition of activated carbon, either sludge-based or commercial, enhanced phenol removal from 58 to 98.7% and from 87 to 93% for COD with feed concentrations of 100 mg phenol l−1 and 2500 mg COD l−1. ...... hiện toàn bộ
Genetic changes that increase 5-hydroxymethyl furfural resistance in ethanol-producing Escherichia coli LY180
Biotechnology Letters - Tập 32 - Trang 661-667 - 2010
The ability of a biocatalyst to tolerate furan inhibitors present in hemicellulose hydrolysates is important for the production of renewable chemicals. This study shows EMFR9, a furfural-tolerant mutant of ethanologenic E. coli LY180, has also acquired tolerance to 5-hydroxymethyl furfural (5-HMF). The mechanism of action of 5-HMF and furfural appear similar. Furan tolerance results primarily from...... hiện toàn bộ
Enhanced production of ATP-binding cassette protein exporter-dependent lipase by modifying the growth medium components of Pseudomonas fluorescens

Isolation of a novelAgrobacteriun spp capable of degrading a range of nitrile compounds
Biotechnology Letters - Tập 16 - Trang 47-50 - 1994
Using soil enrichment techniques we have isolated micro-organisms capable of degrading simple nitrile compounds. One species identified as anAgrobacterium spp. was examined in detail. This isolate was capable of utilising a range of aliphatic and aromatic nitriles as sole sources of carbon and nitrogen. Assays for enzymes involved in nitrile degradation and growth/production studies with this orga...... hiện toàn bộ
Variations of photosynthetic activity and growth of freshwater algae according to ozone contact time in ozone treatment
Biotechnology Letters - Tập 19 - Trang 831-833 - 1997
The activity of freshwater algae in drinking water supply at various ozone contact times was investigated to evaluate ozonation processes used for sterilization of algae. O production rates of algae just after ozonation were severely retarded even by short ozone contact. The algal growth rate was also declined with increase of ozone contact time and completely inhibited by ozonation for 60 min. Th...... hiện toàn bộ
Freeze drying formulation using microscale and design of experiment approaches: a case study using granulocyte colony-stimulating factor
Biotechnology Letters - Tập 34 - Trang 641-648 - 2011
The lyophilization of proteins in microplates, to assess and optimise formulations rapidly, has been applied for the first time to a therapeutic protein and, in particular, one that requires a cell-based biological assay, in order to demonstrate the broader usefulness of the approach. Factorial design of experiment methods were combined with lyophilization in microplates to identify optimum formul...... hiện toàn bộ
Use of TaqMan gene probe for real-time monitoring of acidophilic hydrogen-producing bacteria
Biotechnology Letters - Tập 29 - Trang 1753-1757 - 2007
Using a TaqMan gene probe targeting the 16S rDNA of acidophilic hydrogen-producing bacteria (HPB), the abundance of this HPB in the biomass was found to increase from 0.02 to 72% in a single batch treating rice slurry waste at pH 4.5 over 130 h. The corresponding abundances were 4.4% in the batch operated at pH 5.0 and 0.01–0.02% at pH 5.5–6.5. During the growth phase, the generation time for the ...... hiện toàn bộ
PPARα plays an important role in the migration activity, and the expression of CYP2S1 and CYP1B1 in chrysin-treated HCT116 cells
Biotechnology Letters - Tập 42 - Trang 1581-1595 - 2020
This study aimed to examine the metabolising effect of chrysin by investigating the mRNA expression levels of PPARα and its related cellular mechanisms in HCT116 cells. The mRNA expression of PPARα was significantly induced in HCT116 cells following treatment with chrysin for 36 h, but the mRNA expression of PPARα was inhibited, when the cells were treated with a combination of chrysin and MK886 (...... hiện toàn bộ
Evaluation of xylitol production from corn cob hemicellulose hydrolysate by Candida parapsilosis
Biotechnology Letters - Tập 21 - Trang 891-895 - 1999
Candida parapsilosis was grown for 59 h in a medium containing corn cob hydrolysate consisting of 50 g xylose l−1, 3.0 g glucose l−1, 2.0 g arabinose l−1, and 0.9 g acetic acid l−1. A biomass of 9.1 g l−1 was produced with 36 g xylitol l−1 and 2.5 g ethanol l−1. In a medium containing 50 g xylose l−1 instead of corn cob hydrolysate, the concentrations of cells, xylitol, and ethanol were 8.6 g l−1,...... hiện toàn bộ
Antigenic features of protein carriers commonly used in immunisation trials
Biotechnology Letters - Tập 32 - Trang 1215-1221 - 2010
An aluminium hydroxide adjuvant induced a more elevated and rapid immune responses against short peptides conjugated to the Keyhole Lympet Hemocyanin carrier than immuneasy adjuvant. Furthermore, since carrier proteins may compete with the fused or chemically linked polypeptides in eliciting antigen-specific immune response, we classified the immunogenicity of the most common carrier proteins used...... hiện toàn bộ
