Xanthan gum is a polysaccharide that is widely used as stabilizer and thickener with many industrial applications in food industry. Our aim was to estimate the ability of Xanthomonas campestris ATCC 13951 for the production of xanthan gum by using whey as a growth medium, a by-product of dairy industry. X. campestris ATCC 13951 has been studied in batch cultures using a complex medium for the d...

The wastes and the by-products of food industrial technologies are suitable for bioenergy generating because of the high organic matter content. Anaerobic digestion is the eldest technology for waste stabilization and however by controlled decomposition a high value and marketable energy source can be produced. Whey is normally used as a component of dairy products or as an additive for food pr...

Efficacy of cleaners designed for use with ultrafiltration systems was determined by microbiological evaluation and thmugh visual inspection using scanning elecmn microscopy. The ultrafiltration system containing two commercial-scale, polysulfone membranes was soiled with sweet whey (4OOC) then rinsed with water and membranes were removed. One half of each membrane was snaked for 2 h at 38OC in...

The suitability of polysulfone ultrafiltration membranes (UFM) designed for commercial water treatment has been investigated for separation of protein (PR) from sweet whey. Ultrafiltration (UF) of whey originated from dairy has been realized by a self-made pilot plant, which has been in service for about one year. The influence of two whey temperatures (9 and 30 °C) on the efficiency of protein...
