Microbial activity influences the vicinity of a microbial cell in a way that changes the pH value of the surrounding medium. Key processes are the production or degradation of charged substances (e.g. volatile fatty acids) and the production of carbo

Sizing agents like starch or partly hydrolyzed starch are applied to yarn for an efficient weaving process. The corresponding desizing wastewater makes up about 50% of the organic load in wastewater from textile wet-processing. During the size prepar

A film of sizing agents protects yarn during weaving. Its removal in a subsequent washing process causes 50% of the organic effluent load of textile finishing processes and requires large amounts of auxiliary chemicals (e.g., surfactants). Microbial

A new control strategy for the methanogenic reactor of a two-phase anaerobic digestion system has been developed and successfully tested on the laboratory scale. The control strategy serves the purpose to detect inhibitory effects and to achieve good

The aim of our proposed microbial desizing process is to combine production (cotton desizing) and wastewater treatment in one process and to replace auxiliary chemicals with a mixed microbial culture. Cotton fabric desizing is integrated in the acidi

Although polycyclic aromatic hydrocarbons (PAH) and alkanes are biodegradable at ambient temperature, in some cases low bioavailabilities are the reason for slow biodegradation. Considerably higher mass transfer rates and PAH solubilities and hence b

Textile (eg cotton) finishing industry wastewater is characterised by high concentrations of surfactants (up to 2 g dm−3) and of readily biodegradable biopolymers (COD 5–15 g dm−3). The anionic surfactant decyl sulfate (DS) was chosen as model
