Spore counts, species composition and richness of arbuscular mycorrhizal fungi, and soil glomalin contents were evaluated in a soil contaminated with Zn, Cu, Cd and Pb after rehabilitation by partial replacement of the contaminated soil with non-contaminated soil, and by Eucalyptus camaldulensis planting with and without Brachiaria decumbens sowing. These rehabilitation procedures were compared...

Corn cob is a major component of agricultural and domestic waste in many parts of the world. It is composed mainly of cellulose which can be converted to energy in form of bioethanol as an efficient and effective means of waste management. Production of cellulolytic enzymes were induced in the fungi Aspergillus niger and Penicillium decumbens by growing them in mineral salt medium containing al...

Brachiaria species are cultivated worldwide in tropical and subtropical climates as the main forage source for ruminants. Numerous tropical and warm-season grasses cause hepatogenous photosensitization, among them several species of Brachiaria. Steroidal saponins present in these plants may be responsible for liver damage. However, sporidesmin and other hepatotoxic mycotoxins are likely to prod...

A study of the aerobic degradation of beet molasses alcoholic fermentation wastewater diluted to 50% (chemical oxygen demand, COD: 82 g/l) was carried out using the following fungi: Penicillium sp., Penicillium decumbens , Penicillium lignorum and Aspergillus niger . These four microorganisms produce a decolorization of the wastewater from the first day of incubation, achieving the maximum deco...

Here, we report the draft 2,261,881-bp genome sequence of Caloranaerobacter sp. TR13, isolated from a deep-sea hydrothermal vent on the East Pacific Rise. The sequence will be helpful for understanding the genetic and metabolic features, as well as potential biotechnological application in the genus Caloranaerobacter.

The spittlebugs Mahanarva spectabilis economically challenges cattle production of neotropical regions, due to its voracious feeding on tropical grasses. Here, we evaluated biochemical responses the interaction between M. and widely cultivated grasses Brachiaria spp. (i.e., brizantha decumbens) elephant (cvs. Roxo de Botucatu Pioneiro), regarding lipoxygenases, protease inhibitors, phytohormone...

Thirty-seven warm-season bermudagrass (Cynodon spp.) accessions, two cool-season grasses (Lolium perenne and Festuca arundinacea), 'Transvala' digitgrass (Digitaria decumbens), and Sorghum bicolor were evaluated to determine host suitability and susceptibility to the sting nematode, B. longicaudatus, in a 140-day microcell bioassay. All seven of the evaluated commercial cultivars of Cynodon wer...

The objective of this study was to verify and compare the P availability in an Oxisol cultivated with Megathyrsus maximus cv BRS-Zuri Urochloa decumbens Basilisk predict best soil extractor pastures Southern Amazonia. Two experiments were carried out, one grass other Signal grass. experimental design randomized blocks five doses P2O5 based on maximum capacity adsorption (MCAP), corresponding 0,...

This is the first report on using Catathelasma ventricosum for production of fruiting body and lignocellulosic enzymes. To improve the laccase activity and productivity of mushroom, the substrate was added with different supplements (eight aromatic compounds, Mn2+, and Cu2+). Based on the results, all these supplements can improve the laccase activity and productivity of C. ventricosum, and it ...

The present study aims to determine the hematology, serum biochemistry, and acute phase proteins (APPs) responses of both cerebrospinal fluid (CSF) in sheep fed with low high levels Brachiaria decumbens (B. decumbens) diets at different time phases. A total 30 6-month-old male Dorper cross were randomly divided into three treatment groups consisted 10 each. Treatment 1 (control) Pennisetum purp...
