Research on adsorption of cationic dyes by waste brewer's yeast

2011 International Conference on Electric Technology and Civil Engineering (ICETCE), 2011
The potential of waste brewer's yeast(WBY) used as bio-adsorbent to adsorb BasicGreen(BG) was investigated in this paper. Adsorption of BG was pH-dependent and the optimum pH for cation dye is 5.0 . Kinetic process of Basic Green adsorbed by waste brewery's yeast can well described by pseudo-second-order models.

Preparation of Yeast Extract from Brewer’s Yeast Waste and Its Potential Application as a Medium Constituent

Applied Biochemistry and Biotechnology
Yeast extract serves as a source of nutritional components essential for human dietary requirements, feed formulations, and the vital growth factors and nutrients necessary for microorganisms. However, the production cost of yeast extract using cultivated active dry yeast is relatively high.

Biochemical Methane Potential Determination of the Solid Waste - "Brewer's Spent Yeast" as Optional Anaerobic Waste Treatment

2014
Potential alternative uses of by­products and solid wastes from Brewing Industry should be explored. Large amounts of brewer’s spent yeast (SY) are commonly used as cattle food or as low­value compost; however this waste still has an important potential for energy production.

Sphingolipids of Waste Brewer's Yeast

2004
The aim of our research was to determine the concentration of sphingoid bases, C-18sphinganine, C-18sphingosine and C-18phytosphingosine in different generations of waste brewer's yeast. The second aspect of the research was to ascertain whether there is difference in the concentration of sphingolipids between different generations of waste brewer's ...

Influence of growth phase and zeolite on the sphingoid bases biosythesis in waste brewer's yeast

The FEBS journal, 2006
Sphingolipids are a group of lipids which are present in all eukaryotic cells, particulary in plasma membranes. The backbones of complex sphingolipids (sphingoid bases and ceramides) are important intracellular second messengers that play a role in the regulation of cell growth, differentiation and programmed cell death.

Valorization of damaged rice grains: Optimization of bioethanol production by waste brewer’s yeast using an amylolytic potential from the Paenibacillus chitinolyticus CKS1

Fuel, 2018
Abstract Damaged grains that are not useful for food or feed are abundant and cheap. The main objective of this paper was to valorize damaged rice grains for bioethanol production using presacchararification step followed by simultaneous saccharification and fermentation (SSF) by using waste brewer’s yeast.

Sequential hydrolysis of spent brewer's yeast improved its physico-chemical characteristics and antioxidant properties: A strategy to transform waste into added-value biomolecules

Process Biochemistry, 2019
Abstract The spent brewer's yeast (SBY) is a promising raw material due to its high content of proteins, but cells must be disrupted to release yeast compounds. Our work aimed to study the rupturing of SBY cell wall comparing conventional methods (autolysis and mechanical rupture) with enzymatic hydrolysis using proteolytic enzymes (Brauzyn ...

Application of aqueous two-phase partition in PEG-phosphate systems. Design and implementation of a prototype process for recovery of bulk protein fractions from waste brewer's yeast.

Bioseparation, 1992
The practical development of a process exploiting aqueous two-phase partition in PEG/phosphate systems is described for the recovery and partial purification of a bulk protein fraction from waste Brewer's yeast. Inadequacies in current assumptions concerning de novo process design of such systems necessitated the empirical establishment of conditions ...

Waste Brewer’s Yeast as an Alternative Source of Protein for Use as a Bait in the Management of Tephritid Fruit Flies

2016
Yeast, and products of yeast, are composed of proteins, carbohydrates and minerals that fruit flies can utilize for development. They are being considered widely as alternative sources of protein for baits used for fruit fly suppression. In this chapter, we describe how we used techniques developed in Australia to developed fruit fly protein baits from

ATTRACTION OF THE OLIVE FRUIT FLY TO TWO TYPES OF MODIFIED WASTE BREWER'S YEAST

Book of Abstracts of 60th Croatian and 20th International Symposium on Agriculture
The olive fruit fly (Bactrocera oleae Rossi) is the most economically important olive pest. To limit the economic damage and reduce the use of insecticides, sustainable methods must be developed. Current knowledge suggests that various modified waste brewer's yeasts (WBY) attract certain tephritids, but the interaction between B. oleae and modified WBY
