TL;DR: The review discusses the current knowledge on cellulase production by microorganisms and the genetic controls exercised on it and the challenges in cellulase research especially in the direction of improving the process economics of enzyme production.
Abstract: Microbial cellulases find applications in various industries and constitute a major group of the industrial enzymes. Recently, there is resurgence in utilization of biomass for fuel production employing cellulases and hence forth in obtaining better yields and novel activities. Improving the economics of such processes will involve cost reduction in cellulase production which may be achieved by better bioprocesses and genetic improvement of cellulase producers to yield more of the enzyme. The review discusses the current knowledge on cellulase production by microorganisms and the genetic controls exercised on it. It discusses the industrial applications of cellulases and the challenges in cellulase research especially in the direction of improving the process economics of enzyme production.

TL;DR: In this paper, various technologies currently used for dewatering microalgal cultures along with a comparative study of the performances of the different technologies are reviewed and compared, as well as a comparison of the performance of different technologies.
Abstract: Microalgae dewatering is a major obstruction to industrial-scale processing of microalgae for biofuel prodn. The dil. nature of harvested microalgal cultures creates a huge operational cost during dewatering, thereby, rendering algae-based fuels less economically attractive. Currently there is no superior method of dewatering microalgae. A technique that may result in a greater algal biomass may have drawbacks such as a high capital cost or high energy consumption. The choice of which harvesting technique to apply will depend on the species of microalgae and the final product desired. Algal properties such as a large cell size and the capability of the microalgae to autoflocculate can simplify the dewatering process. This article reviews and addresses the various technologies currently used for dewatering microalgal cultures along with a comparative study of the performances of the different technologies.
