A Repeating Sulfated Galactan Motif Resuscitates Dormant Micrococcus luteus Bacteria

open access: yes, 2018
Only a small fraction of bacteria can autonomously initiate growth on agar plates. Nongrowing bacteria typically enter a metabolically inactive dormant state and require specific chemical trigger factors or signals to exit this state and to resume growth.

Chemical structure and antioxidant activity of a new exopolysaccharide produced from Micrococcus luteus

open access: yesJournal of Genetic Engineering and Biotechnology, 2014
An exopolysaccharide (EPS) reaching a maximum of 13 g/L was isolated from Micrococcus luteus by ethanol precipitation. The crude EPS was purified by chromatography on DEAE-cellulose and Sephacryl S-200, affording a polysaccharide active fraction (AEP ...

Biotransformation of Oleic Acid byMicrococcus luteusCells

open access: yesBioscience, Biotechnology, and Biochemistry, 1994
We isolated bacterial strains tolerant to high concentrations of oleic acid from soil samples, and studied biotransformation of fatty acids with the bacteria. We found that a strain BL0–3 identified as Micrococcus luteus metabolized oleic acid to 10-hydroxystearic acid, 10-oxostearic acid, and 4-oxolauric acid.

Investigation of Biological Removal of Nickel (II) Using the Isolated Bacteria from Industrial Wastewater of Mobarakeh Steel Complex in Isfahan

open access: yesMajallah-i Dānishgāh-i ’Ulūm-i Pizishkī-i Īlām, 2019
Introduction: Heavy metals are among the most stable and non-degradable biological pollutants in the environment that can enter the water, soil, air, and therefore, the food chain. In recent years, biological methods, especially with the help of bacteria,

Biosorption of Strontium from Aqueous Solutions byMicrococcus luteusSr02

open access: yes, 2018
Although strontium (Sr2+) is found in soils, sediments and surface waters, there is limited evidence about its biosorption. In this study, a surface water strain being highly tolerant to Sr2+ was isolated and identified as Micrococcus luteus Sr02 by ...
