Phytoextraction of heavy metal polluted soils using Sedum plumbizincicola inocu...
Ma, Ying; Rajkumar, Mani; Luo, Yongming; Freitas, H.The aim of this study was to investigate the effects of metal mobilizing plant-growth beneficial bacterium Phyllobacterium myrsinacearum RC6b on plant growth and Cd, Zn and Pb uptake by Sedum plumbizincicola under laboratory conditions. Among a collection of metal-resistant bacteria, P. myrsinacearum RC6b was specifically chosen as a most favorable metal mobilizer based on its capability of mobilizing high conc...
Improvement of Ni phytostabilization by inoculation of Ni resistant Bacillus me...
Rajkumar, Mani; Ma, Ying; Freitas, H.The use of metal tolerant plants for the phytostabilization of metal contaminated soil is an area of extensive research and development. In this study the effects of inoculation of Ni-resistant bacterial strains on phytostabilization potential of various plants, including Brassica juncea, Luffa cylindrica and Sorghum halepense, were studied. A Ni-resistant bacterial strain SR28C was isolated from a nickel rich ...
Grain refinement of AZ91D magnesium alloy by MgCO3
Chen,Ti Jun; Jiang,Xiang Dong; Ma,Ying; Wang,Rui Quan; Hao,YuanThe grain refining technique of AZ91D magnesium alloy by MgCO3 has been investigated. The refining mechanism and tensile properties of the resulting alloy have also been discussed. The results indicate that MgCO3 can decrease its grain size from 311 to 53µm. Correspondingly, the tensile properties are obviously improved. The higher the cooling rate from addition temperature to pouring temperature or the higher ...
Familial congenital cyanosis caused by Hb-M Yantai (α-76 GAC → TAC, ...
Sun,Yanbo; Wang,Pingyu; Li,Youjie; Jiao,Fei; Li,Zunling; Ma,Ying; Li,Wei; Xie,ShuyangMethemoglobin (Hb-M) is a rare hemoglobinopathy in China. We hereby report on a family living in Yantai, East China, with congenital cyanosis due to Hb-M mutation. The proband, a 65-year-old female, presented 63% oxygen saturation. Both Hb-M concentration and arterial oxygen saturation remained unchanged, even following intravenous treatment with methylene blue. There was also no change in blood-color (chocolat...

Inoculation of plant growth promoting bacterium Achromobacter xylosoxidans stra...
Ma, Ying; Rajkumar, Mani; Freitas, HelenaIn this study, a copper-resistant plant growth promoting bacterial (PGPB) strain Ax10 was isolated from a Cu mine soil to assess its plant growth promotion and copper uptake in Brassica juncea. The strain Ax10 tolerated concentrations up to 600 mg Cu L-1 on a Luria-Bertani (LB) agar medium and utilized 1-aminocyclopropane-1-carboxylic acid (ACC) as a sole N source in DF salts minimal medium. The strain Ax10 was...
Characterization of metal-resistant plant-growth promoting Bacillus weihensteph...
Rajkumar, Mani; Ma, Ying; Freitas, HelenaA metal-resistant bacterial strain SM3 isolated from a serpentine soil in the north-east of Portugal was characterized as Bacillus weihenstephanensis based on the morphological and biochemical characteristics and on the comparative analysis of the partial 16S ribosomal DNA sequence. Bacillus weihenstephanensis SM3 showed a high degree of resistance to nickel (1500 mg l-1), copper (500 mg l-1) and zinc (700 mg l...
