Última Glucose(xylose) isomerase production by Streptomyces sp. CH7 grown on agricultural residues BJM Chanitnun,Kankiya; Pinphanichakarn,Pairoh. Streptomyces sp. CH7 was found to efficiently produce glucose(xylose) isomerase when grown on either xylan or agricultural residues. This strain produced a glucose(xylose) isomerase activity of roughly 1.8 U/mg of protein when it was grown in medium containing 1% xylose as a carbon source. Maximal enzymatic activities of about 5 and 3 U/mg were obtained when 1% xylan and 2.5% corn husks were used, respectively. The enzyme was purified from a mycelial extract to 16-fold purity with only two consecutive column chromatography steps using Macro-prep DEAE and Sephacryl-300, respectively. The approximate molecular weight of the purified enzyme is 170 kDa, and it has four identical subunits of 43.6 kDa as estimated by SDS-PAGE. Its Km values for glucose and...

Ano: 2012 URL: http://www.scielo.br/scielo.php?script=sci_arttext&pid=S1517-83822012000300035 Draft genome sequence of Streptomyces sp. strain F1, a potential source for glycoside hydrolases isolated from Brazilian soil BJM Melo,Ricardo Rodrigues de; Persinoti,Gabriela Felix; Paixão,Douglas Antonio Alvaredo; Squina,Fábio Márcio; Ruller,Roberto; Sato,Helia Harumi. ABSTRACT Here, we show the draft genome sequence of Streptomyces sp. F1, a strain isolated from soil with great potential for secretion of hydrolytic enzymes used to deconstruct cellulosic biomass. The draft genome assembly of Streptomyces sp. strain F1 has 69 contigs with a total genome size of 8,142,296 bp and G + C 72.65%. Preliminary genome analysis identified 175 proteins as Carbohydrate-Active Enzymes, being 85 glycoside hydrolases organized in 33 distinct families. This draft genome information provides new insights on the key genes encoding hydrolytic enzymes involved in biomass deconstruction employed by soil bacteria.

Ano: 2017 URL: http://www.scielo.br/scielo.php?script=sci_arttext&pid=S1517-83822017000400612 Production of actinomycin-D by the mutant of a new isolate of Streptomyces sindenensis BJM Praveen,Vandana; Tripathi,C.K.M.; Bihari,Vinod; Srivastava,S.C.. An actinomycin-D producing strain was isolated from soil and characterized as Streptomyces sindenensis. The culture was subjected to UV irradiation and a mutant with 400% higher actinomycin-D production was isolated (400 mg/l-1 as compared to 80 mg/l-1 produced by the parent). Production medium was optimized and antibiotic yield with the mutant was enhanced to 850 mg/l-1 which is 963% higher as compared with the parent.

Ano: 2008 URL: http://www.scielo.br/scielo.php?script=sci_arttext&pid=S1517-83822008000400017 Antimicrobial activity of actinomycetes and characterization of actinomycin-producing strain KRG-1 isolated from Karoo, South Africa BJPS Charousová,Ivana; Medo,Juraj; Hleba,Lukáš; Císarová,Miroslava; Javoreková,Soňa. In the present study we reported the antimicrobial activity of actinomycetes isolated from aridic soil sample collected in Karoo, South Africa. Eighty-six actinomycete strains were isolated and purified, out of them thirty-four morphologically different strains were tested for antimicrobial activity. Among 35 isolates, 10 (28.57%) showed both antibacterial and antifungal activity. The ethyl acetate extract of strain KRG-1 showed the strongest antimicrobial activity and therefore was selected for further investigation. The almost complete nucleotide sequence of the 16S rRNA gene as well as distinctive matrix-assisted laser desorption/ionization-time-of-flight/mass spectrometry (MALDI-TOF/MS) profile of whole-cell proteins acquired for strain KRG-1 led to...
