Egg breaking wastes were treated with 1W200 mg./l. chitosan, a by-product /derived from shrimp and crab shells, and 2-20 mg./l. Betz 1130. Suspended solids in the .I wastewater were reduced by 70-90% and the COD by 55-75%. The yield of dry coagulated solids from wastes collected during cleanup was approximately 12 lb./IOKl gal., and from the concentrated wastes in the egg washers, the yield was...

Production of chlorflavonin, a new antifungal antibiotic, by strains of Aspergillus candidus is described. Two wild strains of the fungus had distinctly different chlorflavonin-producing capabilities. One strain produced 25 mug of chlorflavonin per ml per 4 to 5 days in a pilot scale fermentor with stirring, using a medium containing corn steep liquor and glucose. Production of antibiotic was f...

The objective was to evaluate the effect of postmortem aging on marination performance of early-deboned chicken breast fillets (pectoralis major) with different color lightness. Effects of marination on muscle shear force were also determined. Early-deboned (2 h postmortem) broiler butterfly fillets were visually selected based on their color lightness (pale, normal, and dark) from a commercial...

Background: RNAi (RNA interference) is a new strategy in gene therapy and biotechnology which provides new promises in the treatment of different diseases such as cancer and viral diseases. CCND1 which is a key gene in cell cycle is amplified and over expressed in esophageal cancer. The objective of this study was production and siRNAs for CCND1, the key gene in cell cycle. Materials and Metho...

A Requirement is a statement that identifies a product or operational, functional, or design characteristic or constraint, which is unambiguous, testable, or measurable and necessary for product or process acceptability. [3] Requirements Engineering is the branch of systems engineering which address the process of identifying and then monitoring the stakeholders needs and systems required funct...

A simple, nonaseptic, low-cast process for the conversion of cassava, a starchy tropical root crop, into microbial protein for use as animal feed was sought. Screening tests culminated in the isolation of a thermotolerant, amylase-producing mold, designated I-21, which was identified as Aspergillus fumigatus. The optimum pH for protein synthesis was 3-5, but the optimum temperature was less tha...

Editorial When today scientists and bioprocess engineers look at a Microbial Cell Factory for the production of a protein or a metabolite of commercial or research interest, they think at the microorganism of choice first from a (i) molecular, then from a (ii) metabolic and finally from a (iii) process point of view. Analyses and manipulations of the pathway(s) involved in the synthesis of the ...

Life Cycle Assessment (LCA) is the standardised and globally recognised tool for quantifying environmental impact of goods and services. A key aspect in LCA is the consideration of whole life cycle systems. The application of LCA in product development inherently comprises the quest for optimisations on all system levels. However, as the act of ecodesign conventionally focuses on physical produ...
