Carbazole 1,9a-dioxygenase (CARDO) from Pseudomonas sp. strain CA10 is a multicomponent enzyme that catalyzes the angular dioxygenation of carbazole, dibenzofuran, and dibenzo-p-dioxin. It was revealed by gas chromatography-mass spectrometry and 1H and 13C nuclear magnetic resonance analyses that xanthene and phenoxathiin were converted to 2,2',3-trihydroxydiphenylmethane and 2,2',3-trihydroxyd...

The IncP-7 plasmid pCAR1 of Pseudomonas resinovorans CA10 confers the ability to degrade carbazole upon transfer to the recipient strain P. putida KT2440. We designed a customized whole-genome oligonucleotide microarray to study the coordinated expression of pCAR1 and the chromosome in the transconjugant strain KT2440(pCAR1). First, the transcriptome of KT2440(pCAR1) during growth with carbazol...

The present author and coworkers have engaged in the research developments of inorganic phosphate materials with high performance, utilizing characteristic properties phosphates forms crystals glasses. review described our previous regarding (i) preparation fibrous octacalcium (Ca8H2(PO4)6∙5H2O) hydroxyapatite (Ca10(PO4)6(OH)2; HAp) particles due to anisotropic crystal growth, (ii) superplastic...

Hidroksiapatit, Ca10(PO4)6(OH)2 adalah mineral utama penyusun tulang dan gigi. Material pengganti yang tersusun atas hidroksiapatit, telah digunakan secara luas untuk aplikasi biomedis seperti di bidang periodontologi ortopedi. Hidroksiapatit dapat disintesis menggunakan bahan sintetis pula diekstraksi dari hewan laut atau disebut juga sumber biogenik. Biogenik antara lain bersumber koral, spon...

Synthetic hydroxyapatite (Ca10(PO4)6(OH)2, HAp) is very similar to the inorganic part of bones and teeth mammals. It a well-known biomaterial with good biocompatibility, osteoconductivity bioactivity. Nifuroxazide (C12H9N3O5, NFX) broad-spectrum antibacterial drug poorly soluble in water. In order increase solubility NFX, nano-sized HAp powder raw NFX were mixed giving, as result, HAp/NFX conju...
