The anaerobic zones of Lakes Cisó and Vilar (Banyoles karstic area, NE Spain) had mass developments purple sulfur bacteria during summer 1982. In Lake Vilar, Chromatium spp. was dominant (up to 92% the microbial biovolume). Cisó, predominant microorganisms were 71%) another bacterium forming aggregates (20%). bacterial layer could be divided according physiological state cells into a top part maximal specific activity, peak abundance, bottom inactive cells. in predominantly limited by light;...
Abstract Background Pantoea agglomerans strains are among the most promising biocontrol agents for a variety of bacterial and fungal plant diseases, particularly fire blight apple pear. However, commercial registration P. products is hampered because this species currently listed as biosafety level 2 (BL2) organism due to clinical reports an opportunistic human pathogen. This study compares plant-origin in search discriminating genotypic/phenotypic markers using multi-locus phylogenetic...
The antibacterial activity against bacterial plant pathogens and its relationships with the presence of cyclic lipopeptide (cLP) biosynthetic genes ituC (iturin), bmyB (bacillomycin), fenD (fengycin) srfAA (surfactin), their corresponding antimicrobial peptide products have been studied in a collection 64 strains Bacillus spp. isolated from environments. most frequent (AMP) were bmyB, (34-50% isolates). Most isolates (98.4%) produced surfactin isoforms, 90.6% iturins 79.7% fengycins. was...
The use of lactic acid bacteria (LAB) to control multiple pathogens that affect different crops was studied, namely, Pseudomonas syringae pv. actinidiae in kiwifruit, Xanthomonas arboricola pruni Prunus and fragariae strawberry. A screening procedure based on vitro planta assays the three bacterial successful selecting potential LAB strains as biological agents. antagonistic activity 55 first tested Lactobacillus plantarum CC100, PM411 TC92, Leuconostoc mesenteroides CM160 CM209 were...
Accurate studies of the pigment composition and isolation in pure cultures Chlorobiaceae from samples eight Spanish lakes show that there are two main coexisting groups green brown Chlorobium spp. represented respectively by limicola phaeobacteroides . Laboratory experiments with mixed isolated strains light quality plays a selective role on species among This selection depends which determines vivo absorption spectrum cells as well their ability to adjust intracellular concentration...
ABSTRACT Short peptides of 11 residues were synthesized and tested against the economically important plant pathogenic bacteria Erwinia amylovora , Pseudomonas syringae Xanthomonas vesicatoria compared to previously described peptide Pep3 (WKLFKKILKVL-NH 2 ). The antimicrobial activity 22 analogues was evaluated in terms MIC 50% effective dose (ED 50 ) for growth. Peptide cytotoxicity human red blood cells stability toward protease degradation also determined. several inhibited growth three...
Abstract BACKGROUND: Commercially available fruits and raw ready‐to‐eat vegetables ( n = 445) were examined for aerobic, coliform, yeast mould counts using normalised methods. Listeria spp., monocytogenes Salmonella spp. detected by real time polymerase chain reaction (QPCR) after enrichment. RESULTS: Aerobic plate ranged from < 10 to > 9 colony‐forming units (CFU) g −1 , with the lowest highest recorded sprouts respectively. The incidence level of coliforms was found in vegetables, up...
Cecropin A is a natural antimicrobial peptide that exhibits rapid, potent and long-lasting lytic activity against broad spectrum of pathogens, thus having great biotechnological potential. Here, we report system for producing bioactive cecropin in rice seeds.Transgenic plants expressing codon-optimized synthetic gene drived by an endosperm-specific promoter, either the glutelin B1 or B4 were generated. The signal sequence from N-terminally fused to coding A. We also studied whether presence...
Antimicrobial and plant defence elicitor peptides have received attention on last decades as novel tools to combat bacterial diseases. We previously reported a library of peptide conjugates resulting from the combination an antimicrobial (BP16, BP143, BP387 or BP475) sequence (flg15, BP13, Pep13 PIP1). From this library, we selected set 14 including both highly poorly active sequences performed structure-activity relationship study by NMR MD simulations. Analysis their structure in 30%...
The antifungal activity of cecropin A(2-8)-melittin(6-9) hybrid undecapeptides, previously reported as active against plant pathogenic bacteria, was studied. A set 15 sequences screened in vitro Fusarium oxysporum, Penicillium expansum, Aspergillus niger, and Rhizopus stolonifer. Most compounds were highly F. oxysporum (MIC < 2.5 microM) but less the other fungi. best peptides studied for their sporicidal Sytox green uptake microconidia. significant inverse linear relationship observed...
ABSTRACT A set of 31 undecapeptides, incorporating 1 to 11 d -amino acids and derived from the antimicrobial peptide BP100 (KKLFKKILKYL-NH 2 ), was designed synthesized. This evaluated for inhibition growth plant-pathogenic bacteria Erwinia amylovora , Pseudomonas syringae pv. syringae, Xanthomonas axonopodis vesicatoria, hemolysis, protease degradation. Two derivatives were as active BP100, 10 peptides displayed improved activity, with all- isomer being most active. Twenty-six less...
Abstract Background The Biopeptide BP100 is a synthetic and strongly cationic α-helical undecapeptide with high, specific antibacterial activity against economically important plant-pathogenic bacteria, very low toxicity. It was selected from library of peptides, along other peptides activities relevant bacterial fungal species. Expression the series in plants major interest to establish disease-resistant facilitate molecular farming. Specific challenges were small length, peptide...
