in this work, mathematical modeling of microbial(trichosporon sp.) biomass production in a stirred tankbioreactor and in an external airlift bioreactor has beeninvestigated. a model based on a tanks-in-seriesmodel without back-flow has been used to simulate theproduction of single cell protein in the external airliftbioreactor under an unsteady condition and withoutoxygen limitation, utilizing ...

Considering the projected demand for protein supplementation in animal feed, as well prioritizing plant-based provision growing human population, great stress is imposed on conventional sources, calling new sustainable alternatives. In this regard, production and application of single-cell proteins (SCPs) has proven to be a promising alternative. Therefore, study, volatile fatty acids (VFAs) ef...

Although the 20-amino acid presequence present in 15-kDa pro-sterol carrier protein-2 (pro-SCP-2, the precursor of the mature 13-kDa SCP-2) alters the function of SCP-2 in lipid metabolism, the molecular basis for this effect is unresolved. The presequence dramatically altered SCP-2 structure as determined by circular dichroism, mass spectroscopy, and antibody accessibility such that pro-SCP-2 ...

Although in vitro studies suggest a role for sterol carrier protein-2 (SCP-2) in cholesterol trafficking and metabolism, the physiological significance of these observations remains unclear. This issue was addressed by examining the response of mice overexpressing physiologically relevant levels of SCP-2 to a cholesterol-rich diet. While neither SCP-2 overexpression nor cholesterol-rich diet al...

On the basis of their abilities to bind bile acids and/or cholesterol, the physiological role(s) of liver fatty acid-binding protein (L-FABP) and sterol carrier protein (SCP) 2/SCP-x (SCP-2/SCP-x) gene products in biliary bile acid and cholesterol formation was examined in gene-ablated male mice. L-FABP (LKO) or L-FABP/SCP-2/SCP-x [triple-knockout (TKO)] ablation markedly decreased hepatic bile...

Alphaviruses are enveloped, insect-borne viruses, which contains a positive-sense RNA genome. The protein capsid is surrounded by a lipid membrane, which is penetrated by glycoprotein spikes. The structure of the Sindbis virus (SINV) (the type virus) core protein (SCP) was previously determined and found to have a chymotrypsin-like structure. SCP is a serine proteinase which cleaves itself from...

In the present study Candida utilis was employed for the production of single cell protein (SCP) from wheat bran using solid state fermentation in 250ml Erlenmeyer flask. Various cultural conditions were also optimized for the maximum yield of cell biomass of Candida utilis. Maximum cell biomass was obtained when wheat bran was supplemented with 2% molasses as carbon and 0.25% ammonium nitrate ...

The food crisis due to the global population boom requires agriculture revolutions and a transition sustainable, affordable sources of proteins. Single cell protein (SCP) derived from microorganisms such as brewer's yeast is one best possible options meet challenges. Utilization carbon nitrogen recovered waste streams, instead sugar-rich substrate, for yeast-driving SCP production could improve...

abstract these days, scientsts search for cheap protein sources because of growthing of population.one of these sources is single cell protein.this study deals with single cell protein production process by saccharomyces cerevisiae and saccharomyces carlsbergensis .these yeast are known as the most ideal and practical eukaryotic microorganism in biological studies. in this survey we added the w...

To help advance the understanding of cloud life cycle and improve model skill in representing clouds, Deng et al. (2003a and b) investigated cloud processes, and developed a mass-flux-based shallow/deep convection parameterization (SCP, hereafter referred as the Penn State SCP) scheme that involves all aspects of the cloud life cycle, including dynamics, microphysics and radiation. In the Penn ...
