A practical approach for the removal of cationic surfactants using planktonic and immobilized bacterial cells
(Inst Biology, 2019-05-20)
Among the efforts directed at remediating contaminated sites, the use of immobilized microorganisms is an appealing alternative because it offers several advantages over the use of free cells, including protecting cells ...
Enzyme or whole cell immobilization for efficient biocatalysis: focusing on novel supporting platforms and immobilization techniques
(Corporación Universidad de la Costa, 2021)
Cyclodextrin glycosyltransferase production by free cells of Bacillus circulans DF 9R in batch fermentation and by immobilized cells in a semi-continuous process.
Cyclodextrin glycosyltransferase (CGTase) catalyzes the starch conversion into cyclic or linear oligosaccharides, important industrial products. In this work, conditions to increase the enzyme production from Bacillus ...
Bioremediation of Heavy Metals by Cells or Metabolites Microbial Immobilized
(CRC Press - Taylor & Francis Group, 2018)
Heavy metals concentrations in the environment increases alarmingly. Heavy metals profoundly affect biological systems either positively because they are essential in low concentrations or negatively because they are toxic. ...
Petroleum oil removal by immobilized bacterial cells on polyurethane foam under different temperature conditions
(Pergamon-Elsevier Science Ltd, 2017-05)
In this work, a mixed biofilm composed by Pseudomonas monteilii P26 and Gordonia sp. H19 was formed using polyurethane foam (PUF) as immobilization support, for crude oil removal from artificial sea water. Fresh immobilized ...
Cell immobilization technique for the enhanced removal of lindane using Streptomyces strains isolated from Northwestern Argentina
Lindane (γ-HCH) is an organochlorine insecticide which has a negative effect as a pollutant agent of soil, water and sediments. Nowadays it has been banned in almost all countries of the world, but its residues still remain ...
Cell immobilization strategies for biotransformations
This review deals with up-to-date applications related to cell immobilization used for varied biocatalytic purposes in diverse areas ranging from the food and dairy industry, synthesis of added value products such as ...
Removal of the insecticide diazinon from liquid media by free and immobilized Streptomyces sp. isolated from agricultural soil
(Wiley VCH Verlag, 2013-12-11)
From an agricultural soil that had received continuous applications of organophosphorus pesticides, 30 actinobacteria strains were isolated. Two strains, identified as Streptomyces sp. AC1-6 and Streptomyces sp. ISP4, were ...
Scaling up and kinetic model validation of Direct Black 22 degradation by immobilized Penicillium chrysogenum
(IWA Publishing, 2018-01)
This research was undertaken to develop tools that facilitate the industrial application of an immobilized loofah-fungi system to degrade Direct Black 22 (DB22) azo dye. In laboratory-scale tests, the DB22, and loofah as ...
Immobilization of gold nanoparticles on living cell membranes upon controlled lipid binding
(American Chemical Society, 2010-08)
We present a versatile and controlled route to immobilize gold nanoparticles (NPs) on the surface of living cells, while preserving the sensing and optothermal capabilities of the original colloid. Our approach is based ...
