Abstract Mexico is one of the largest agricultural producers in Latin America and generates a large amount residue. The aim this study was to establish usefulness four main Mexican crops (corn, wheat, sugarcane, Agave ) as feedstock for lignocellulosic bioethanol production. residue ratio (RR), defined weight (in tons) per ton product, measured by sampling crop fields 11 geographic regions Mexico. chemical composition, assessed Fourier‐transform infrared spectroscopy (FTIR) carbon‐13 nuclear...
Background Demographic compensation is a complex process by which populations can compensate for the effects of anthropogenic disturbance and other environmental changes restore growth-rate stability ( λ » 1). Dynamic equilibrium achieved when growth rate [λ] close to one. This enables population persist under changing conditions. The demographics fragmented provides an ideal model explore processes adapt through demographic responses. Aims To characterize Quercus oleoides detect various...
Summary The fate of organic matter during composting is poorly understood. Therefore, we analysed composts sewage sludges and green wastes (44 samples representative 11 stages biodegradation) by conventional chemical methods: pH, humic (HA) fulvic acid (FA) content, C, N (OM) 13 C CPMAS NMR to assess the decomposition process matter. Chemical changes clearly occurred in two phases: first, OM first 2 months was characterized decreased C/N ratios, content increased pH; second, a humification...
The effect of atrazine concentrations on mycelial growth and ligninolytic enzyme activities eight native macrofungi isolated in Veracruz, México, were evaluated a semi-solid culture medium. Inhibition rates significantly affected (p=0.05) by (468, 937, 1875, 3750 mg/l). In accordance with the median effective concentration (EC50), Pleurotus sp. strain 1 proved to be most tolerant isolate (EC50=2281.0 mg/l), although its activity was not highest. Pycnoporus sanguineus 2, Daedalea elegans...
Ethanol has been pointed out as a laccase inducer. However, there are controversial reports about its efficiency with some fungi. In this study, we hypothesized that ethanol induced in Pycnoporus sanguineus depends on nitrogen nutriment conditions. To prove this, assessed production submerged cultures of P. sanguineus, different concentrations and with, or without added factorial designed experiment. order to analyze the effects factors response variables, ANOVA, response-surface models were...
Summary Organic matter mineralization of forest litter is catalysed by the action different extracellular enzymes produced microorganisms. Coupling enzyme activities with data on general macromolecular structure organic matter, provided cross‐polarization magic angle spinning 13 C nuclear magnetic resonance ( CPMAS NMR), allows researchers new insights into degradation processes. In this paper, effect temperature incubation processes was evaluated in three distinct layers (OhLn, OhLv and...
Summary We show the presence of interfering substances when total microbial activity in litter samples is measured with fluorescein diacetate (FDA), and we propose some methodological modifications to avoid such interference. Three distinct layers (the OhLn, OhLv OhLf) evergreen oak ( Quercus ilex L.) were characterized by 13 C CPMAS NMR spectra that recalcitrant aromatic phenolic compounds increase degree degradation litter. A wide range sources interference hydrolysis FDA was found. To...
Chemical changes in leaf input to forest soils have been reported affect decay processes. In this work, litter mass loss and decomposition constants (k) during 200 days solid-state fermentation of the native tree Celtis tala Gill. ex Planch. exotic one Ligustrum lucidum Ait. with three common saprotrophic basidiomycetes were compared. Alterations quality characterized by 13 C NMR spectroscopy, pH, soluble sugars, ammonium, proteins, phenol content determination associated extracellular...
Abstract Alkaline and biological lignocellulose pre‐treatments are commonly used to enhance enzymatic hydrolysis improve ethanol production. In this study, 13 C CPMAS NMR spectroscopy was describe changes in sugarcane bagasse (SCB) pre‐treated with NaOH, Ca(OH) 2 Pycnoporus sanguineus . Changes the contents of alkyl C, Carboxyl Aromatic (tertiary, quaternary p‐hydroxyphenyl C), O ‐alkyl amino acids, ergosterol chitin, as well crystallinity index cellulose were observed. Through a...
We identified diverse bradyrhizobia having distinct ERIC-PCR genomic fingerprints from native American trees Inga vera and Lysiloma spp. In addition, two nodule isolates recovered divaricatum seedlings inoculated with soil the tropical house of a UK botanical garden were also as Bradyrhizobium. Genomes obtained (with sizes around 9 Mb each) nine bradyrhizobial isolates; plasmids detected in strains analyzed. Average Nucleotide Identity whole genomes revealed five novel Bradyrhizobium...
