Assessing Bacillus subtilis biosurfactant effects on the biodegradation of petroleum products
(Environmental Monitoring And Assessment, 2015-01-01) [Artigo]
Microbial pollutant removal capabilities can be determined and exploited to accomplish bioremediation of hydrocarbon-polluted environments. Thus, increasing knowledge on environmental behavior of different petroleum products ...
Structure and Biogenesis of Roussoellatide, a Dichlorinated Polyketide from the Marine-Derived Fungus Roussoella sp DLM33
(Organic Letters, 2015-11-06) [Artigo]
The structure of the fungal metabolite roussoellatide (1) has been established by spectroscopic and X-ray diffraction analyses. Results from feeding experiments with [1-C-13]acetate, [2-C-13]acetate, and [1,2-C-13]acetate ...
Escovopsis trichodermoides sp nov., isolated from a nest of the lower attine ant Mycocepurus goeldii
(Antonie Van Leeuwenhoek International Journal Of General And Molecular Microbiology, 2015-03-01) [Artigo]
Currently, five species are formally described in Escovopsis, a specialized mycoparasitic genus of fungus gardens of attine ants (Hymenoptera: Formicidae: tribe Attini). Four species were isolated from leaf-cutting ants ...
Marine-derived fungi: diversity of enzymes and biotechnological applications
(Frontiers In Microbiology, 2015-04-10) [Artigo]
The ocean is considered to be a great reservoir of biodiversity. Microbial communities in marine environments are ecologically relevant as intermediaries of energy, and play an important role in nutrient regeneration cycles ...
Leaf-cutter ant fungus gardens are biphasic mixed microbial bioreactors that convert plant biomass to polyols with biotechnological applications
(Applied And Environmental Microbiology, 2015-07-01) [Artigo]
Leaf-cutter ants use plant matter to culture the obligate mutualistic basidiomycete Leucoagaricus gongylophorus. This fungus mediates ant nutrition on plant resources. Furthermore, other microbes living in the fungus garden ...
Screening the toxicity and biodegradability of petroleum hydrocarbons by a rapid colorimetric method
(Archives Of Environmental Contamination And Toxicology, 2015-02-01) [Artigo]
Crude oil and petroleum products have a wide variety of hazardous components with high toxicity and low biodegradability. Certain dyes change their colors by intercepting electron transfer reactions during the transformation ...
Neutron activation analysis for chemical characterization of Brazilian oxo-biodegradable plastics
(Journal Of Radioanalytical And Nuclear Chemistry, 2015-01-01) [Artigo]
The chemical characterization of oxo-biodegradable plastic bags was performed by neutron activation analysis. The presence of several chemical elements (As, Br, Ca, Co, Cr, Fe, Hf, K, La, Na, Sb, Sc, Ta and Zn) with large ...
Biodegradation of PP and PE blended with PHBV in soil samples
(Advances In Polymer Technology, 2015-06-01) [Artigo]
This work studied the biodegradation of polyethylene/poly(hydroxybutyrate-co-hydroxyvalerate) (PE/PHBV) and polypropylene/PHBV (PP/PHBV) films, by respirometry in soil, using biometric flasks. Additionally, the characteristics ...
Biodegradation of films of low density polyethylene (LDPE), poly(hydroxibutyrate-co-valerate) (PHBV), and LDPE/PHBV (70/30) blend with Paecilomyces variotii
(Polimeros-ciencia E Tecnologia, 2015-01-01) [Artigo]
The increased consumption of plastics in the world has been a subject of great concern and special attention by the scientific community. The aim is to promote development of materials that are biodegradable in a shorter ...
