Rhodococcus sp. P14 was isolated from crude oil-contaminated sediments. This strain was capable of utilizing three to five rings polycyclic aromatic hydrocarbons (PAHs) including phenanthrene (Phe), pyrene (Pyr), and benzo[a]pyrene (BaP) as a sole carbon and energy source. After cultivated with 50mg/L of each PAH, strain P14 removed 43% Phe, 34% Pyr and 30%(More)
A bacterial strain BAP5 with a relatively high degradation ability of benzo[a]pyrene (BaP) was isolated from marine sediments of Xiamen Western Sea, China and identified as Ochrobactrum sp. according to 16S rRNA gene sequence as well as Biolog microbial identification system. Strain BAP5 could grow in mineral salt medium with 50 mg/L of BaP and degrade(More)
Two antifungal peptides, named EAFP1 and EAFP2, have been purified from the bark of Eucommia ulmoides Oliv. Each of the sequences consists of 41 residues with a N-terminal blockage by pyroglutamic acid determined by automated Edman degradation in combination with the tandem mass spectroscopy and the C-terminal ladder sequencing analysis. The primary(More)
AIMS Isolation and characterization of an agarase-producing bacterium Agarivorans sp. HZ105. METHODS AND RESULTS An agarase-producing bacterium strain HZ105 had been isolated from marine sediment sample. Based on phylogenetic analysis of the 16S rRNA gene sequence and phenotypic analysis, as well as biochemical analyses, this strain was named Agarivorans(More)
A β-agarase gene hz2 with 2,868 bp was cloned from the marine agarolytic bacterium Agarivorans sp. HZ105. It encoded a mature agarase HZ2 of 102,393 Da (920 amino acids). Based on the amino acid sequence similarity, agarase HZ2 was assigned to the glycoside hydrolase family 50. The β-agarase shared a gene sequence identity of 98.6% with the reported but(More)
ATHK1 has been implicated in drought and salt tolerance in Arabidopsis thaliana. In this study, the full-length coding sequence of ATHK1 was introduced into Lycium barbarum L. by Agrobacterium transformation. Our results indicated that the transgenic plants tolerated high concentrations of NaCl or water deprivation and exhibited faster recovery following(More)
A novel yellow-pigmented, agarolytic bacterial strain, designated ZC1T, was isolated from the surface of the marine red alga Porphyra haitanensis collected near Nan Ao Island, Guangdong province, China. The isolate was Gram-stain-negative, strictly aerobic and rod-shaped and displayed β-galactosidase, alkaline phosphatase, catalase and oxidase activities.(More)
An agar-degrading bacterium, Catenovulum sp. X3, was isolated from the seawater of Shantou, China. A novel β-agarase gene agaXa was cloned from the strain Catenovulum sp. X3. The gene agaXa consists of 1,590 bp and encodes a protein of 529 amino acids, with only 40 % amino acid sequence identity with known agarases. AgaXa should belong to the glycoside(More)
Polycyclic aromatic hydrocarbons (PAHs) are harmful persistent organic pollutants, while the high-molecular-weight (HMW) PAHs are even more detrimental to the environment and human health. However, microbial anaerobic degradation of HMW PAHs has rarely been reported. One facultative anaerobe Pseudomonas sp. JP1 was isolated from Shantou Bay, Shantou, China,(More)
Hemocyanin is an extracellular copper-containing protein present in the hemolymph of both mollusks and arthropods. The traditionally recognized function of hemocyanin is for oxygen transport. Lately, it was demonstrated that hemocyanin is a multifunctional protein, especially participating in multiple roles of immune defense. For better understanding its(More)
