Improvement of SCP production and BOD removal of whey with mixed yeast culture Electron. J. Biotechnol.
Moeini,Hassan; Nahvi,Iraj; Tavassoli,Manoochehr.
This research emphasizes on single cell protein (SCP) production and Biochemical Oxygen Demand (BOD) removal from whey with mixed yeast culture. For this purpose, 11 yeast strains were isolated from dairy products (M1-M11) and the strains were identified by morphological and physiological properties. These yeast strains were tested for their ability to reduce the BOD and to produce SCP from whey. Among these strains, K. lactis (M2) had the most SCP production from whey with the yield of 11.79 g/l. Ammonium sulphate as nitrogen source had an increasing effect on biomass yield. The mixed culture of the isolated yeast strains with Saccharomyces cerevisiae was used in order to increase the biomass yield and BOD removal. The highest biomass yield (22.38 g/l)...

Whey upgrading by enzyme biocatalysis Electron. J. Biotechnol.
Illanes,Andrés.
Whey is a co-product of processes for the production of cheese and casein that retains most of the lactose content in milk. World production of whey is estimated around 200 million tons per year with an increase rate of about 2%/per year. Milk production is seasonal, so surplus whey is unavoidable. Traditionally, whey producers have considered it as a nuisance and strategies of whey handling have been mostly oriented to their more convenient disposal. This vision has been steadily evolving because of the upgrading potential of whey major components (lactose and whey proteins), but also because of more stringent regulations of waste disposal. Only the big cheese manufacturing companies are in the position of implementing technologies for their recovery and...

Thirty eight pigs born from same sow were divided into 2 group,and fed with or without cheese whey. Pigs were slaughtered after 137-172 days when the live weight was nearly 110kg. Samples of M. longissimus thoracis were analyzed for physicochemical properties. There was no significant difference in the pH,water content and colour appearance in pork between the whey and control group. Crude protein content of the whey group (21.7%) was significantly lower than that of the control (22.6%). Drip loss was measured at 1,5 and 10 days after slaughter,and the drip loss measured at 10 days was significantly lower in the whey group (25.4%) than that of the control (27.1%). Cooking loss was measured at 5 days after slaughter,was significantly lower in the whey group...

Therapeutic properties of whey used as fermented drink Rev. Microbiol.
Kar,T.; Misra,A.K..
Bioconversion of whey for preparation of beverage was standardized by utilizing yoghurt cultures. The product, wheyghurt drink, made with 4% yoghurt cultures inoculated in deproteinized whey (4.8% lactose, 0.66% ash, 0.46% fat and 0.40% protein adjusted to pH 6.4) and incubated at 42oC for 8h had all the technological requisite and dietetic criteria required in the product. The factors affecting the antibacterial activity of wheyghurt drink against Escherichia coli, Staphylococcus aureus, Shigella dysenteriae and Bacillus cereus were determined. There was a significant variation (P<0.05) in the antibacterial activity of wheyghurt drink with different levels of inoculum (1,2,4, and 8%) and concentration of sugar at 37, 42 and 45oC. Incubation at 42oC...

Production of L(+) lactic acid using Lactobacillus casei from whey BABT
Panesar,Parmjit S.; Kennedy,John F.; Knill,Charles J.; Kosseva,Maria.
The aim of this work was to study the fermentation of whey for the production of L(+) lactic acid using Lactobacillus casei. The effect of different process parameters such as pH of the medium, temperature, inoculum size, age of inoculum, agitation and incubation time was monitored to enhance the lactose conversion in whey to L(+) lactic acid. Fermentations were performed without any pH control. The optimization of the fermentation conditions resulted in significant decrease in fermentation time, besides increase in lactose conversion to lactic acid. The optimized process conditions resulted in high lactose conversion (95.62%) to L(+) lactic acid production (33.73 g/L) after an incubation period of 36 h.

Hydrolysis of whey lactose by immobilized β-Galactosidase BABT
Mariotti,Marcela Panaro; Yamanaka,Hideko; Araujo,Angela Regina; Trevisan,Henrique Celso.
Hydrolysis of whey lactose to glucose and galactose by immobilized galactosidase comes as an alternative to enlarge the possibilities of commercial use of this feedstock. To be applied at industrial scale, the process should be performed continuously .This work aimed to study the hydrolysis of whey lactose by an immobilized enzyme reactor. b-Galactosidase from Aspergillus oryzae was immobilized on silica and activity and stability were evaluated. The best immobilization results were attained by using glutaraldehyde as support's activator and enzyme stabilizer. The optimized enzyme proportion for immobilization was 15-20 mg g-1 of support. Treatments of whey were performed (microfiltration, thermal treatment and ultrafiltration), seeking the elimination of...

Action of a pancreatin and an Aspergillus oryzae protease on whey proteins: correlation among the methods of analysis of the enzymatic hydrolysates BABT
Morais,Harriman Aley; Silvestre,Marialice Pinto Coelho; Silveira,Josianne Nicácio; Silva,Ana Cristina Simões e; Silva,Viviane Dias Medeiros; Silva,Mauro Ramalho.
The objectives of this study were to hydrolyze whey proteins using a pancreatin and an Aspergillus oryzae protease; to evaluate the degree of hydrolysis (DH) and the peptide profile; and to establish the correlations among the analytical methods. Ten hydrolysates were prepared at different reaction times and the highest DH was obtained by the protein content method. Good correlations (r > 0.87) between the methods of formaldehyde and orthophthalaldehyde (OPA), formaldehyde and osmometry as well as osmometry and OPA were observed using pancreatin. Similar results were obtained between OPA and soluble protein content for the A. oryzae protease. The action of pancreatin produced the highest contents of di- and tripeptides (9.07, 7.12 and 6.46%) and the...
