Abstract
Istamycins (ISMs) are 2-deoxyfortamine-containing aminoglycoside antibiotics (AGAs) produced by Streptomyces tenjimariensis ATCC 31603 with broad-spectrum bactericidal activities against most of the clinically relevant pathogens. Therefore, this study aimed to statistically optimize the environmental conditions affecting ISMs production using the central composite design (CCD). Both the effect of culture media composition and incubation time and agitation rate were studied as one factor at the time (OFAT). The results showed that both the aminoglycoside production medium and the protoplast regeneration medium gave the highest specific productivity. Results also showed that 6 days incubation time and 200 rpm agitation were optimum for their production. A CCD quadratic model of 17 runs was employed to test three key variables: initial pH, incubation temperature, and concentration of calcium carbonate. A significant statistical model was obtained including, an initial pH of 6.38, incubation temperature of 30 ˚C, and 5.3% CaCO3 concentration. This model was verified experimentally in the lab and resulted in a 31-fold increase as compared to the unoptimized conditions and a threefold increase to that generated by using the optimized culture media. To our knowledge, this is the first report about studying environmental conditions affecting ISM production as OFAT and through CCD design of the response surface methodology (RSM) employed for statistical optimization. In conclusion, the CCD design is an effective tool for optimizing ISMs at the shake flask level. However, the optimized conditions generated using the CCD model in this study should be scaled up in a fermenter for industrial production of ISMs by S. tenjimariensis ATCC 31603 considering the studied environmental conditions that significantly influence the production proces.

Abstract
Lichens are structured associations of a fungus with a cyanobacteria and/or green algae in a symbiotic relationship, which provide specific habitats for diverse bacterial communities, including actinomycetes. However, few studies have been performed on the phylogenetic relationships and biosynthetic potential of actinomycetes across lichen species. In the present study, a total of 213 actinomycetes strains were isolated from 35 lichen samples (22 lichen genera) collected in Yunnan Province, China. 16S rRNA gene sequence analysis revealed an unexpected level of diversity among these isolates, which were distributed into 38 genera, 19 families, and 9 orders within the Actinobacteria phylum. The detailed taxa of isolates had no clear relationship to the taxonomic affiliations of the associated lichens. To the best of our knowledge, this is the first report to describe the isolation of Actinophytocola, Angustibacter, Herbiconiux, Kibdelosporangium, Kineosporia, Kitasatospora, Nakamurella, Nonomuraea, Labedella, Lechevalieria, Lentzea, Schumannella, and Umezawaea species from lichens. At least 40 isolates (18.78%) are likely to represent novel actinomycetes taxa within 15 genera. In addition, all 213 isolates were tested for antimicrobial activity and screened for genes associated with secondary metabolite production to evaluate their biosynthetic potential. These results demonstrate that the lichens of Yunnan Province represent an extremely rich reservoir for the isolation of a significant diversity of actinomycetes, including novel species, which are potential source for discovering biologically active compounds.

Abstract
In this study, an efficient high-performance liquid chromatography (HPLC)-electrospray ionization (ESI)-ion trap-tandem mass spectrometry (MS/MS) was developed for the identification of the biosynthetic congeners involved in the aminocyclitol aminoglycosidic fortimicin pathway from Micromonospora olivasterospora fermentation. The usage of both acid extraction (pH ∼2.5) followed by an cationic-exchanging SPE cleanup and pentafluoropropionic acid mediated ion-pairing chromatography with ESI-ion trap-MS/MS detection was determined to be sufficiently practical to profile the fortimicin (FOR) congeners produced in a culture broth. The limit of the quantification for the fortimicin A (FOR-A) standard spiked in the culture broth was ∼1.6 ng mL(-1). The average recovery rate was 93.6%, and the intra- and inter-day precisions were <5% with accuracy in the range from 87.1 to 94.2%. Moreover, the epimeric mixtures including FOR-KH, FOR-KR, and FOR-B were separately resolved through a macrocyclic glycopeptide (teicoplanin)-bonded chiral column. As a result, ten natural FOR pseudodisaccharide analogs were identified and semi-quantified in descending order as follows: FOR-A, FOR-B, DCM, FOR-KH plus FOR-KR, FOR-KK1, FOR-AP, FOR-KL1, FOR-AO, and FOR-FU-10. This is the first report on both the simultaneous characterization of diverse structurally closely related FORs derived from bacterial fermentation using HPLC-ESI-ion trap-MS/MS analysis and the chromatographic separation of the three FOR epimers.

Abstract
Micromonospora olivasterospora, a fortimicin A (FTM A, astromicin) producer, was found to carry an enzyme that converts FTM A to N-formimidoyl FTM A (FI-FTM A). This enzyme (FI-FTMase) was purified to homogeneity and shown to be a flavin adenine dinucleotide (FAD) enzyme. Tracer experiments proved that the formimidoyl group was derived from C-2 of glycine via oxidation of the amino acid in the presence of FTM A and oxygen. The gene encoding this enzyme, fms 14, was cloned using a 26-mer oligonucleotide probe, designed according to the N-terminal amino acid sequence of purified FI-FTMase, from a cosmid clone pGLM990, which has been shown to contain a cluster of FTM A biosynthetic genes. The nucleotide sequence, and biochemical and genetic analysis revealed that FI-FTMase is composed of four identical subunits of mol. wt. 52,000, and contains at least one FAD per subunit. DNA regions homologous to fms14 were found in two other producers of the fortimicin group of antibiotics, Dactylosporangium matsuzakiense ATCC31570 and Micromonospora sp. SF-2098.

Abstract
The cloning of five DNA segments carrying at least seven genes (fms1, fms3, fms4, fms5, fms7, fms11, and fms12) that participate in fortimicin A (astromicin) biosynthesis was described previously. These DNA fragments were used to screen a cosmid library of genomic DNA in order to examine if these biosynthetic genes are clustered in Micromonospora olivasterospora. One cosmid clone (pGLM990) was obtained, which hybridized to all the probes. Complementation analysis, using mutants blocked at various steps and chimeric plasmids subcloned from pGLM990, showed that three additional genes (fms8, fms10, and fms13) are present in pGLM990. A gene conferring self-resistance to the antibiotic, which was independently cloned in Streptomyces lividans, using the plasmid vector pIJ702 was also found to be linked to the cluster of biosynthetic genes. Thus, at least ten biosynthetic genes and a self-defense gene are clustered in a chromosomal region of about 27 kb in M. olivasterospora. Interestingly, the fms8 gene which participates in the dehydroxylation step of fortimicin A biosynthesis was found to have homology with a neomycin resistance gene nmrA from the neomycin-producing Micromonospora sp. MK50. Studies using a cell-free extract of the fms8 mutant and its parent strain showed that the enzyme encoded by fms8 phosphorylates a biosynthetic precursor, fortimicin KK1, in the presence of ATP. Thus the dehydroxylation reaction is suggested to occur via the phosphorylation of the target hydroxyl group. DNA regions homologous to fms genes were found in Micromonospora sp. SF-2098 and Dactylosporangium matsuzakiense, both producers of fortimicin group antibiotics.

Abstract
We have developed a gene-cloning system in Micromonospora olivasterospora, a fortimicin A (astromicin) producer. Plasmids of Micromonospora from two strains of M. olivasterospora were used for construction of the vectors. Two antibiotic-resistance genes, nmrA and nmrB, cloned from a neomycin-producing Micromonospora, were introduced into these plasmids for the selection of transformants. In a new protoplasting protocol for lysozyme-resistant bacteria, protoplasts of M. olivasterospora were found in short-time incubation with lysozyme and transformed efficiently, indicating that the method was suitable to shotgun cloning. Using this system, seven biosynthetic genes for fortimicin A were cloned. Their physical maps revealed that at least four of these genes were clustered. Analysis of a cosmid library of M. olivasterospora showed that eleven biosynthetic genes and a self-defense gene existed in a region of approx. 25 kb of DNA.

Abstract
We have cloned the seven genes that are responsible for biosynthesis of the antibiotic fortimicin A (FTM A) using a recently developed self-cloning system that employes the plasmid vector pMO116 for Micromonospora olivasterospora. Five chimeric plasmids that restored FTM A production in M. olivasterospora mutants blocked at different biosynthetic steps were isolated by shotgun cloning. Secondary transformation using other non-producing mutants showed that two additional FTM A biosynthetic genes were included on these plasmids, and that at least four of the genes were clustered. Interestingly AN38-1, a non-producing mutant that had a defect in dehydroxylation of a precursor of FTM A, was complemented by the DNA fragment containing a neomycin resistance gene that had been cloned from a neomycin-producing strain (Micromonospora sp. FTM A non-producing strain) in the course of constructing the plasmid vector pMO116. These results clearly show that this novel gene cloning system in Micromonospora is of practical use.

Abstract
O-Demethylfortimicin A (compound A49759) was tested against 445 bacteria, and the results were compared with those obtained with fortimicin A, amikacin, gentamicin, netilmicin, sisomicin, and tobramycin. A49759 was found to be active and bactericidal against the Enterobacteriaceae, nonfermentative gram-negative bacilli, and Staphylococcus aureus. A49759 was two- to fourfold more active than fortimicin A against most species tested, but generally fourfold less active than amikacin against this population of Pseudomonas aeruginosa (85% inhibited at less than or equal to 16 microgram of amikacin per ml and 85% inhibited at less than or equal to 64 microgram of A49759 per ml). Only amikacin and A49759 were resistant to most aminoglucoside-inactivating enzymes and also had significant antipseudomonal activity. Amikacin was inactivated by aminoglycoside 6'-acetyltransferase, and A49759 was inactivated by aminoglycoside 3-acetyltransferase. The minimal inhibitory concentrations of all tested aminoglycosides were increased by augmenting the inoculum size.
