| optimization of d-lactic acid production using unutilized biomass as substrates by multiple parallel fermentation. | this study investigated the optimization of d-lactic acid production from unutilized biomass, specifically banana peel and corncob by multiple parallel fermentation (mpf) with leuconostoc mesenteroides and aspergillus awamori. the factors involved in mpf that were assessed in this study comprised banana peel and corncob, kh2po4, tween 80, mgso4·7h2o, nacl, yeast extract, and diammonium hydrogen citrate to identify the optimal concentration for d-lactic acid production. optimization of these comp ... | 2016 | 28330258 |
| immobilization of halophilic aspergillus awamori em66 exochitinase on grafted k-carrageenan-alginate beads. | a novel extreme halophilic exochitinase enzyme was produced by honey isolate aspergillus awamori em66. the enzyme was immobilized successfully on k-carrageenan-alginate gel carrier (ca) with 93 % immobilization yield. the immobilization process significantly improved the enzyme specific activity 2.6-fold compared to the free form. the significant factors influencing the immobilization process such as enzyme protein concentration and loading time were studied. distinguishable characteristics of o ... | 2016 | 28330097 |
| [influence of uv-radiation on physical-chemical and functional properties of free immobilized glucoamylase from aspergillus awamori]. | the effect of uv light (240-390 nm) at the doses of 151-1510 j/m2 on the catalytic activity of free and im- mobilized glucoamylase from aspergillus awamori was investigated. it was established that the loss of catalytic activity of the enzyme was associated with photochemical transformations of trp-120, which is part of the active site of glucoamylase. it was shown that the use of collagen as a carrier for immobilization of glucoamylase reduces the constant photoinactivation of the enzyme. it wa ... | 2016 | 25427372 |
