Crude bacterial extracts of two new Streptomyces sp isolates as bio-colorants for textile dyeing
(Springer, Dordrecht, 2014)
Renewed demand for incorporation of natural dyes (bio-colorants) in textile industry could be met through biotechnological production of bacterial pigments. Two new Streptomyces strains (NP2 and NP4) were isolated for the ...
CFD analysis of the influence of centrifugal separator geometry modification on the pulverized coal distribution at the burners
(Transactions of Famena, 2014)
This paper presents the results of 3D numerical flow simulation in the ventilation mill (VM) and air mixture channel (AMC) of Kostolac B power plant, where a centrifugal separator with adjustable blade angle is used. ...
Preparation of cellulosic fibers with biological activity by immobilization of trypsin on periodate oxidized viscose fibers
(Springer, Dordrecht, 2014)
In this study, a biologically active fibrous material was designed by immobilizing trypsin on viscose fibers. The viscose yarn was first oxidized with sodium periodate to produce aldehyde groups and then employed as a ...
