Heavy usage of gasoline, burgeoning fuel prices, and environmental issues have paved the way for exploration cellulosic ethanol. Cellulosic ethanol production technologies are emerging require continued technological advancements. One most challenging is pretreatment lignocellulosic biomass desired sugars yields after enzymatic hydrolysis. We hypothesized that consecutive dilute sulfuric acid-dilute sodium hydroxide would overcome native recalcitrance sugarcane bagasse (SB) by enhancing...
Background Independent surveys across the globe led to proposal of a new basidiomycetous yeast genus within Bulleromyces clade Tremellales, Bandoniozyma gen. nov., with seven species. Methodology/Principal Findings The species were characterized by multiple methods, including analysis D1/D2 and ITS nucleotide sequences, morphological physiological/biochemical traits. Most can ferment glucose, which is an unusual trait among yeasts. Conclusions/Significance In this study we propose...
We profiled the microfungal communities in gardens of fungus-growing ants to evaluate possible species-specific ant–microfungal associations and assess potential dependencies diversity on ant foraging behavior. In a 1-year survey, we isolated microfungi from nests ofCyphomyrmex wheeleri, Trachymyrmex septentrionalis andAtta texana Central Texas. Microfungal prevalence was higher ofC. wheeleri (57%) than ofT. (46%) andA. (35%). Culture-dependent methods coupled with polyphasic approach...
Leafcutter ants propagate co-evolving fungi for food. The nearly 50 species of leafcutter (Atta, Acromyrmex) range from Argentina to the United States, with greatest diversity in southern South America. We elucidate biogeography cultivated by using DNA sequence and microsatellite-marker analyses 474 cultivars collected across range. Fungal belong two clades (Clade-A Clade-B). dominant widespread Clade-A form three genotype clusters, their relative prevalence corresponding America, northern...
Diminishing supplies of fossil fuels and oil spills are rousing to explore the alternative sources energy that can be produced from non-food/feed-based substrates. Due its abundance, sugarcane bagasse (SB) could a model substrate for second-generation biofuel cellulosic ethanol. However, efficient bioconversion SB remains challenge commercial production We hypothesized oxalic-acid-mediated thermochemical pretreatment (OAFEX) would overcome native recalcitrance by enhancing cellulase...
For the implementation of cellulosic ethanol technology, maximum use lignocellulosic materials is important to increase efficiency and reduce costs. In this context, appropriate pentose released by hemicellulose hydrolysis could improve de economic viability process. Since Saccharomyces cerevisiae unable ferment pentose, search for pentose-fermenting microorganisms be an alternative. work, isolation yeast strains from decaying vegetal materials, flowers, fruits insects their application...
The focus of this study was the identification compounds from plant extracts for use in crop protection. This paper reports on toxic activity fractions leaf Ricinus communis L (Euphorbiaceae) and isolated active leaf-cutting ant Atta sexdens rubropilosa Forel its symbiotic fungus Leucoagaricus gongylophorus (Singer) Möller. main responsible against R were found to be fatty acids former ricinine ants.
Nine limonoids were isolated from Carapa guianensis and Cedrela fissilis. Among them, 1,2-dihydro-3beta-hydroxy-7-deacetoxy-7-oxogedunin is a new compound. Moreover, the assignments of some chemical shifts xyloccensin k have been corrected ¹H NMR data 7-deacetylgedunin assigned for first time. These assayed on Atta sexdens rubropilosa workers showing moderate insecticidal activities.
Endophytic fungi were isolated from leaves, flowers and fruit of healthy apple trees (Malus domestica , Borkh.) growing in southern Brazilian orchards under three different cultivation systems (conventional, integrated organic), during two vegetative cycles. The greatest total number endophytic isolates was obtained the organic when compared to conventional systems. Filamentous genera Colletotrichum Xylaria Botryosphaeria most frequent ones representative yeast Sporobolomyces Rhodotorula...
Thirty-nine yeast strains were recovered from a field nest of primitive and putative novel attine ant species in the genus Myrmicocrypta (Hymenoptera: Formicidae: tribe Attini). Yeasts isolated fungus garden waste deposit included Candida dubliniensis , oleophila Cryptococcus haglerorum Hanseniaspora uvarum . In addition, one morphological type was overwhelmingly. Sequencing data partial large-subunit (LSU) rDNA internal transcribed spacer (ITS) region coupled with physiological...
