Two new antibiotics, A-218 and K-41. Isolation and characterization.

Isolation and characterization of bacteria from the lesion of juvenile sea cucumber Holothuria scabra (Jaeger, 1938) with symptom of skin ulceration disease

Echinoderm diseases have attracted little interest in contrast to the other commercial marine organisms. This study reports the pathogenesis pattern of juvenile Holothuria scabra. 11 pure bacteria were isolated from lesions of juvenile H. scabra with the symptoms of skin ulceration disease. Phylogenetic identification based on 16S rRNA gene sequences analysis revealed that they belonged to the ...

Isolation and Characterization of a New Peroxisome Deficient CHO Mutant Cell Belonging to Complementation Group 12

We searched for novel Chinese hamster ovary (CHO) cell mutants defective in peroxisome biogenesis by an improved method using peroxisome targeting sequence (PTS) of Pex3p (amino acid residues 1–40)-fused enhanced green fluorescent protein (EGFP). From mutagenized TKaEG3(1–40) cells, the wild-type CHO-K1 stably expressing rat Pex2p and of rat Pex3p(1–40)-EGFP, numerous cell colonies resistant to...

New antiviral antibiotics; xanthocillin X mono- and dimethylether, and methoxy-xanthocillin X dimethylether. I. Isolation and characterization. (Studies on antiviral and antitumor antibiotics. V).

The production, isolation, chemical and physical characteristics and biological properties of the new antiviral antibiotics, xanthocillin X monoand dimethylether, and methoxy-xanthocillin X dimethylether are described. They were produced by two strains of Aspergillus sp. isolated from soil samples. The active principles were extracted from the mycelium, and isolated as yellowish crystals. They ...

Isolation and Characterization of Burkholderia Cepacia Strains from Hospitalized Patients in the Hospitals of West Guilan Province

Abstract Background and Objective: Burkholderia cepacia complex (BCC) is a plant pathogen that is an important mortality factor in immune-compromised and hospitalized patients. We aimed to Isolate and Characterize the Burkholderia Cepacia Strains from Hospitalized Patients in the Hospitals of West Guilan Province. Material and Methods: This study was conducted on 90 saliva and blood ...
