Microbial Degradation of Native Keratin in Batch Fermentation

Keratinases and microbial degradation of Keratin

The present review deals with fungal keratinases including that of dermatophytes. Bacterial keratinases were also included. Temperature and substrate relationship keratinase production has also been discussed. Keratin degradation and industrial involvement of keratinase producing fungi is also reviewed.

The scale-up of microbial batch and fed-batch fermentation processes.

Photocatalytic Degradation of Ciprofloxacin pharmacy pollutant in Batch Photoreactor

Background & Aims of the Study: Pharmaceutical compounds have a variety of forms and applications. Specific amounts of toxic organic compounds in the process of their manufacturing and utilization cause environmental pollution problems. So, degradation and removal these compounds are necessary. The aim of this paper is the study photocatalytic degradation of ciprofloxacin drug in aqueous soluti...

Determination of keratin degradation by fungi using keratin azure.

Azure dye-impregnated sheep's wool keratin (keratin azure) was incorporated in a high pH medium and overlaid on a keratin-free basal medium. The release and diffusion of the azure dye into the lower layer indicated production of keratinase. Fifty-eight fungal taxa, including 49 members of the Arthrodermataceae, Gymnoascaceae and Onygenaceae (Order Onygenales), were assessed for keratin degradat...

Modeling and optimal control of a nonlinear dynamical system in microbial fed-batch fermentation

The mathematical model and optimal control of microbial fed-batch fermentation is considered in this paper. Since it is decisive for increasing the productivity of 1,3propanediol (1,3-PD) to optimize the feeding rate of glycerol and the switching instants between the batch and feeding processes in the fermentation process, we propose a new nonlinear dynamical system to formulate the process. In...
