Journal ArticleDOI
Developments in wastewater treatment in the meat processing industry: A review
TL;DR: A review of progress in the treatment of wastewater from slaughterhouses is presented in this article, where significant progress in issues such as nutrient removal and high-rate anaerobic treatment are highlighted.
Journal ArticleDOI
Effect of C/N ratio and aeration on the fatty acid composition of heterotrophic Chlorella sorokiniana
Feng Chen,Michael R. Johns +1 more
TL;DR: The results demonstrate that the fatty acid composition and lipid content of heterotrophically-grown microalgae can be favourably manipulated by varying culture conditions.
Journal ArticleDOI
Effect of pH and nitrogen source on pigment production by Monascus purpureus
Ming-Ho Chen,Michael R. Johns +1 more
TL;DR: The effect of pH and nitrogen source on pigment production by Monascus purpureus 192F using glucose as the carbon and energy source, was studied in pH-controlled, batch fermentor cultures using HPLC analysis to determine individual pigment concentrations.
Journal ArticleDOI
Culture conditions affect the molecular weight properties of hyaluronic acid produced by Streptococcus zooepidemicus
TL;DR: Replicate experiments performed under conditions resulting in the lowest (40(deg)C, anaerobic) and highest (40 g of glucose per liter, 1-vol/vol/min aeration)-M(infw) polymer demonstrated excellent experimental reproducibility.
Journal ArticleDOI
Production of pigments by Monascus purpureus in solid culture
TL;DR: The effect of physical and nutritional factors on the production of pigments byascus purpureus FRR 2190 was studied using cultures grown on both rice and a synthetic medium that was solidified with carrageenan and extruded into rice-like particles as mentioned in this paper.
