This article overviews the enzymes produced by microorganisms, which have been extensively studied worldwide for their isolation, purification and characterization of their specific properties. Researchers have isolated specific microorganisms from extreme sources under extreme culture conditions, with the objective that such isolated microbes would possess the capability to bio-synthesize spec...
Propolis, a resinous substance collected by Apis mellifera bees from various plant sources is transformed in the presence of bee enzymes. Short- and long-term effects of diet supplementation with ethanol extract of Iranian propolis (EEIP) was investigated on growth and immunity in juvenile rainbow trout. The fish (mean body weight 30 ± 3.2 g) were fed a commercial diet supplemented with 0 (cont...
Commercially available enzymes do not contain all the necessary softwood-specific accessory enzymes to obtain high saccharification efficiency. In this work, six saprophytic fungi obtained from Pinus radiata plantation site were screened for the putative softwood-specific accessory enzyme, β-mannanase. A Penicillium sp. was found to produce β-mannanase in both solid (31.6 units/g of dry biomass...
Microbial enzymes are enabling new technologies for processing pulps and fibers. Xylanases reduce the amount of chemicals required for bleaching; cellulases smooth fibers, enhance drainage, and promote ink removal; lipases reduce pitch; lignin-degrading enzymes remove lignin from pulps. Several of these processes are commercial, and others are beginning to emerge. In the future, enzyme-based pr...
The conjugation of High Performance Computing (HPC) and Grid paradigm with applications based on commercial software is one among the major challenges of today e-Infrastructures. Several research communities from either industry or academia need to run high parallel applications based on licensed
Previous studies of commercial software enterprises have employed industry-level analyses, or have focused on major players in the industry. There is, therefore, a dearth of in-depth research on small-to-medium software enterprises (SMSE). The need to understand the institutional contexts and firm-specific capabilities of such firms is important, as they account for over 90% of software enterpr...
This paper reports the findings of an investigation of children’s performance and attitude towards a paper based and computer based test. Twenty children, aged between 7 and 8 of mixed gender, participated in this study using a commercial software application. The children’s attitude towards the software was captured through the use of a smarty-o-meter to indicate their level of preference and ...
Nanozymes (NZs) are nanostructured artificial enzymes that mimic catalytic properties of natural enzymes. The NZs have essential advantages over enzymes, namely low preparation costs, stability, high surface area, self-assembling capability, size and composition-dependent activities, broad possibility for modification, biocompatibility. wide potential practical applications as catalysts in bios...
