Journal ArticleDOI
Plastics derived from biological sources: present and future: a technical and environmental review.
TL;DR: In short, petrochemical plastics are not sustainable and bio-based sustainable plastics should be developed to avoid problems caused by the petro chemical plastics.
Journal ArticleDOI
Progress in Metabolic Engineering of Saccharomyces cerevisiae
TL;DR: The current review discusses the relevance of several engineering strategies, such as rational and inverse metabolic engineering, evolutionary engineering, and global transcription machinery engineering, in yeast strain improvement and summarizes existing tools for fine-tuning and regulating enzyme activities and thus metabolic pathways.
Journal ArticleDOI
Recovery of carboxylic acids produced by fermentation
TL;DR: In-situ removal of carboxylic acid by extraction during fermentation is the most popular approach, but recovery of the extractant can easily lead to waste inorganic salt formation, which counteracts the advantage of the in-Situ removal.
Journal ArticleDOI
Fumaric acid production by fermentation
Carol A. Roa Engel,Adrie J. J. Straathof,Tiemen W. Zijlmans,Walter M. van Gulik,Luuk A.M. van der Wielen +4 more
TL;DR: Submerged fermentation systems coupled with product recovery techniques seem to have achieved economically attractive yields and productivities and future prospects for improvement of fumaric acid production include metabolic engineering approaches to achieve low pH fermentations.
Journal ArticleDOI
Progress in inhibition mechanisms and process control of intermediates and by-products in sewage sludge anaerobic digestion
Haiping Yuan,Nanwen Zhu +1 more
TL;DR: In this article, a detailed summary of the researches was discussed on the inhibition of the anaerobic digestion process and the controlling and recovery of the inhibitors as valuable products were also reviewed in detail.

Book
Introduction to organic chemistry
TL;DR: The covalent bond and shapes of molecules are discussed in detail in this paper, where Amino acids and proteins are represented as nucleophilic aliphatic substitution, and the reaction of benzene and phenols.
Journal ArticleDOI
Extraction chemistry of fermentation product carboxylic acids
A. S. Kertes,C. J. King +1 more
TL;DR: High distribution ratios are measured when long-chain tertiary amines are employed as extractants, forming bulky salts preferentially soluble in the organic phase, and the extractive transfer process obeys the Nernst law.
Journal ArticleDOI
Technological and economic potential of poly(lactic acid) and lactic acid derivatives
TL;DR: The development and deployment of novel separations technologies, such as electrodialysis with bipolar membranes, extractive distillations integrated with fermentation, and chemical conversion, can enable low-cost production with continuous processes in large-scale operations and can use environmentally sound processes to produce environmentally useful products from lactic acid.

Handbook of Solvent Extraction
TL;DR: In this paper, the basic principles of Mixer-Settler design are presented. But they do not consider the use of a simple box-type mixer-settler.
Journal ArticleDOI
Counter-current and simulated counter-current adsorption separation processes
Douglas M. Ruthven,Chi Bun Ching +1 more
TL;DR: In this paper, the application of countercurrent and simulated counter-current process schemes to adsorption separations is reviewed with emphasis on industrial-scale operations and mathematical modelling, and the results of the application are presented.
