Journal ArticleDOI
Role of cultivation media in the development of yeast strains for large scale industrial use
Bärbel Hahn-Hägerdal,Kaisa Karhumaa,Christer Larsson,Marie F. Gorwa-Grauslund,Johann F. Görgens,Willem H. van Zyl +5 more
TL;DR: Media for heterologous protein production and for bulk bio-commodity production are summarized and the effects of complex, defined and industrial media are compared.
Journal ArticleDOI
Production of char from vacuum pyrolysis of South-African sugar cane bagasse and its characterization as activated carbon and biochar
TL;DR: In this paper, the potential of vacuum pyrolysis to convert sugar cane bagasse into char materials for wastewater treatment and soil amendment is the focus of a research paper, where the authors obtained char with the required porous structure, making it very efficient as adsorbent both in terms of methylene blue (MB) adsorption with a N 2 -BET surface area of 418 m 2 ǫg −1.
Journal ArticleDOI
Fungal β-mannanases: Mannan hydrolysis, heterologous production and biotechnological applications
TL;DR: Application of fungal β-mannanases in the production of nutraceuticals, food and feed, and commodity products is discussed, indicating production of enzymes at levels up to grams per litre and with high purity, making these production systems ideal for industrial enzyme production.
Journal ArticleDOI
Non-isothermal kinetic analysis of the devolatilization of corn cobs and sugar cane bagasse in an inert atmosphere
A. O. Aboyade,A. O. Aboyade,Thomas Hugo,Marion Carrier,Edson L. Meyer,R. Stahl,Johannes H. Knoetze,Johann F. Görgens +7 more
TL;DR: In this article, a non-isothermal thermogravimetric analysis in the heating rate range of 10−50°Cmin −1 was performed on corn cobs and sugar cane bagasse.
Journal ArticleDOI
Exergy analysis of a lignocellulosic-based biorefinery annexed to a sugarcane mill for simultaneous lactic acid and electricity production
Mortaza Aghbashlo,Mohsen Mandegari,Meisam Tabatabaei,Somayeh Farzad,Mohamad Mojarab Soufiyan,Johann F. Görgens +5 more
TL;DR: In this paper, a lignocellulosic biorefinery annexed to a sugar mill for simultaneous lactic acid and electricity production using sugarcane bagasse and brown leaves as feedstock.
