Abstract

Eighty-nine Actinomycetes strains were tested for their viability, morphological and physiological characteristics after being kept under paraffin oil overlay and distilled water for a period between 10-30 years. Most of the studied strains belong to the "Lorenzo De Montemayor" collection. Almost all the recovered strains were 28-30 years old and had never been subcultured since the paraffin oil was overlaid. 71.4% of viable Streptomycetes strains had been kept on Sabouraud-dextrose agar and 28.6% were kept on Negroni and Bonfiglioli-medium. Streptomyces violaceusruber produced its characteristic pigment even after 28 years under these conditions. All of the recovered strains were tested for their biological activity, but only Streptomyces lavendulae showed growth-inhibition against Staphylococcus aureus and Bacillus subtilis.

Binding mechanisms for Thermobifida fusca Cel5A, Cel6B, and Cel48A cellulose-binding modules on bacterial microcrystalline cellulose.

The family II cellulose-binding modules (CBM) from Thermobifida fusca Cel5A and Cel48A were cloned in the Escherichia coli/Streptomyces shuttle vector pD730, and the plasmids were transformed into Streptomyces lividans TKM31. CBM(Cel5A), and CBM(Cel48A), CBM(Cel6B) were expressed and purified from S. lividans. The molecular masses were determined by mass spectrometry, and the values were 10595 +/- 2, 10915 +/- 2, and 11291 +/- 2 Da for CBM(Cel5A), CBM(Cel6B), and CBM(Cel48A), respectively. Three different binding models (Langmuir, Interstice Penetration, and Interstice Saturation) were tested to describe the binding isotherms of these CBMs on bacterial microcrystalline cellulose (BMCC). The experimental binding isotherms of T. fusca family II CBMs on BMCC are best modeled by the Interstice Saturation model, which includes binding to the constrained interstice surface of BMCC as well as traditional Langmuir binding on the freely accessible surface. The Interstice Saturation model consists of three different steps (Langmuir binding, interstice binding, and interstice saturation). Full reversibility only occurred in the Langmuir region. The irreversibility in the interstice binding and saturation regions probably was caused by interstice entrapment. Temperature shift experiments in different binding regions support the interstice entrapment assumption. There was no systematic difference in binding between the two types of exocellulase CBMs--one that hydrolyzes cellulose from the nonreducing (CBM(Cel6B)) end and one that hydrolyzes cellulose from the reducing end (CBM(Cel48A)).

Characterization of the early stage aminoshikimate pathway in the formation of 3-amino-5-hydroxybenzoic acid: the RifN protein specifically converts kanosamine into kanosamine 6-phosphate.

The biosynthesis of 3-amino-5-hydroxybenzoic acid (AHBA), precursor of the ansamycin and mitomycin antibiotics, proceeds by the aminoshikimate pathway from 3,4-dideoxy-4-amino-D-arabino-heptulosonic acid 7-phosphate (aminoDAHP). Identification of RifN, product of one of three genes from the rifamycin biosynthetic gene cluster known to be essential for aminoDAHP formation, as a specific kanosamine (3-deoxy-3-amino-D-glucose) 6-kinase establishes kanosamine and its 6-phosphate as specific intermediates in AHBA formation. This suggests a hypothetical reaction sequence for aminoDAHP formation, and thus for the early steps of AHBA biosynthesis, starting from UDP-D-glucose and introducing the nitrogen by oxidation and transamination at C-3.
