Cadmium uptake by Spirulina maxima: toxicity and mechanismWorld Journal of Microbiology and Biotechnology - Tập 14 - Trang 579-581 - 1998
A.C. Augusto da Costa, F.P. de França
Cadmium uptake by Spirulina maxima cells was more pronounced in living than in
dead cells, with a maximum recovery of 47.63mg Cd/g cells for living cells and
37.00mg Cd/g cells for inactivated cells. When in the medium at 1.2mg/l, cadmium
affected cell growth and diminished cell productivity. Cadmium was detected in
the outer and inner faces of the external membrane, essentially in the lipid
layer... hiện toàn bộ
Decolourization of textile dye Reactive Violet 5 by a newly isolated bacterial consortium RVM 11.1World Journal of Microbiology and Biotechnology - Tập 21 - Trang 667-672 - 2005
Safia Moosvi, Haresh Keharia, Datta Madamwar
Soil samples collected from contaminated sites of Vatva, Gujarat, India were
studied for screening and isolation of organisms capable of decolourizing
textile dyes. A bacterial consortium RVM 11.1 was selected on the basis of rapid
dye decolourization. Reactive Violet 5 (RV 5) was used as model dye. The
consortium exhibited 94% decolourization ability within 37 h under a wide pH
range from 6.5 to ... hiện toàn bộ
Characterization of a secreted cholesterol oxidase from Rhodococcus sp.GKI (CIP 105335)World Journal of Microbiology and Biotechnology - Tập 15 - Trang 579-585 - 1999
A. Elalami, J. Kreit, A. Filali-Maltouf, J. Boudrant, P. Germain
Extracellular cholesterol oxidase (COX) (EC 1.1.3.6) was produced by Rhodococcus
sp. GK1 cells grown in a defined mineral salt medium containing a mixture of
phytosterols (sitosterol, campesterol, stigmasterol) as the sole source of
carbon and energy. In the same time, the sterols acted as enzyme inducers. The
medium was enriched with yeast extract in order to stimulate enzyme secretion.
COX was p... hiện toàn bộ
Antibacterial activity of Bacillus licheniformis B6 against viability and biofilm formation of foodborne pathogens of health importanceWorld Journal of Microbiology and Biotechnology - Tập 38 - Trang 1-13 - 2022
Pablo R. Díaz, María J. Torres, Gabriela Petroselli, Rosa Erra-Balsells, Marcela Carina Audisio
We studied a strain of Bacillus isolated from an artisanal tannery in Salta,
Argentina. It was identified as Bacillus licheniformis B6 by 16 S phylogenetic
analysis and MALDI TOF (GenBank accession code No. KP776730). The synthesis of
lipopeptides by B6 and their antibacterial activity against clinical pathogenic
strains was analyzed both in the cell-free supernatant (CFS) and in the crude
fractio... hiện toàn bộ
Antioxidative properties and inhibitory effect of Bifidobacterium adolescentis on melanogenesisWorld Journal of Microbiology and Biotechnology - Tập 28 - Trang 2903-2912 - 2012
Huey-Chun Huang, Tsong-Min Chang
Melanin is a dark pigment produced by melanocytes. Tyrosinase is a key enzyme
which catalyzes the rate-limiting step of melanogenesis. However, accumulation
of melanin leads to various skin hyperpigmentation disorders. To find a novel
skin-whitening agent, the antioxidant capacity of Bifidobacterium adolescentis
culture filtrate and inhibitory effect on melanogenesis were investigated. The
antioxi... hiện toàn bộ
A novel enterocin T1 with anti-Pseudomonas activity produced by Enterococcus faecium T1 from Chinese Tibet cheeseWorld Journal of Microbiology and Biotechnology - Tập 32 - Trang 1-9 - 2016
Hui Liu, Lanwei Zhang, Huaxi Yi, Xue Han, Wei Gao, Chunliang Chi, Wei Song, Haiying Li, Chunguang Liu
An enterocin-producing Enterococcus faecium T1 was isolated from Chinese Tibet
cheese. The enterocin was purified by SP-Sepharose and reversed phase HPLC. It
was identified as unique from other reported bacteriocins based on molecular
weight (4629 Da) and amino acid compositions; therefore it was subsequently
named enterocin T1. Enterocin T1 was stable at 80–100 °C and over a wide pH
range, pH 3.0... hiện toàn bộ
