25. Forage cactus associated with different fiber sources for lactating Sindhi cows: intake, digestibility and microbial protein production
This experiment was carried to evaluate the effect of forage cactus with different fiber sources (elephant grass hay [EGH], corn straw [CS], hay of cassava shoots [HCS], fresh sugarcane bagasse [FSB], and hydrolyzed sugarcane bagasse [HSB]) on intake, apparent digestibility and macrobiotic protein production of cows. Five cows with 265 kg average body weight

27. 1,3-propanodiol: produção, aplicações e potencial biotecnológico
1,3-propanediol is a high-value specialty chemical which has many industrial applications. Its main use is the production of the polymer polypropylene terephthalate, a thermoplastic used in the textile and automobile industries. The interest in 1,3-propanediol production from glycerol bio-conversion has increased after the employment of biodiesel by various

28. Effect of whey fermented by Enterococcus faeciumin consortium with Veilonella parvulaon ruminal bacteria in vitro
The objective of this research was to evaluate the effect of whey fermented by Enterococus faecium in consortium with Veilonella parvula in vitro on ruminal microorganisms in different substrates, with or without monensin. The first experiment was carried out in a completely randomized design, in a 6 × 3 factorial arrangement (six substrates × three whey l

29. Effects of phenolic compounds in propolis on digestive and ruminal parameters in dairy cows
Four rumen-cannulated primiparous lactating cows were studied in a 4 × 4 Latin square design experiment to evaluate the effects of propolis-based products (PBP) with different concentrations of propolis and alcohol levels on total digestibility, (TD), ruminal digestibility (RD), intestinal digestibility (ID), pH, ruminal ammonia-nitrogen production (NH3-N),

30. Prebiotic inulin: Useful dietary adjuncts to manipulate the livestock gut microflora
In recent years, there has been a growing appreciation on the relevance of gastrointestinal microflora in both ruminants and non-ruminants owing to revelation of their role in several physiological functions including digestion, nutrient utilization, pathogen exclusion, gastrointestinal development, immunity system, gut gene expression and quality of animal

31. Rumen fermentation and rumen microbes in Nellore steers receiving diets with different lipid contents
The objective of the present study was to evaluate the effects of dietary lipid content (20, 40 and 60 g/kg dry matter) on intake, total and ruminal apparent digestibility of dry matter (DM), nutrient digestibility, rumen fermentation parameters, microbial synthesis efficiency and rumen microbial content of beef cattle. Nine cannulated steers at 6 months of

32. Hemocidinas derivadas da hemoglobina: estruturas, propriedades e perspectivas
The increasing incidence of microbial infections, high toxicity, and high level of resistance associated with conventional antibiotics has created a need for new drugs. Antimicrobial peptides (AMPs) constitute a promising alternative and/or an important source of knowledge given their ability to inhibit the growth and/or to kill bacteria, fungi, parasites an

33. Silver nanoparticle production by the fungus Fusarium oxysporum: nanoparticle characterisation and analysis of antifungal activity against pathogenic yeasts
The microbial synthesis of nanoparticles is a green chemistry approach that combines nanotechnology and microbial biotechnology. The aim of this study was to obtain silver nanoparticles (SNPs) using aqueous extract from the filamentous fungus Fusarium oxysporum as an alternative to chemical procedures and to evaluate its antifungal activity. SNPs production

34. Grão de soja em suplementos múltiplos para novilhas de corte em pastejo / Soybean in multiple supplements for grazing beef heifers
This dissertation was prepared from two experiments with beef heifers submitted to different supplementation strategies on pasture. In the first experiment aimed to evaluate the effect of replacing soybean meal by soybean at different levels in multiple supplements on the nutritional characteristics and productive performance of heifers grazing in Uruchloa d

35. Complexos metálicos de hidrazonas, tiossemicarbazonas e lapachol: atividade farmacológica e avaliação de relações estrutura-atividade
The present work comprises the synthesis and characterization of metal compounds with bioactive ligands and the study of their pharmacological profile. Anti-inflammatory, antimicrobial, antiparasitic and antitumor drug candidates were designed. Complex [Zn(LASSBio-466)H2O]2 was synthesized with salicylaldehyde-2-chlorobenzoyl hydrazone (H2LASSBio-466), while

36. Production of gaba (γ - aminobutyric acid) by microorganisms: a review
GABA (γ-aminobutyric acid) is a four carbon non-protein amino acid that is widely distributed in plants, animals and microorganisms. As a metabolic product of plants and microorganisms produced by the decarboxylation of glutamic acid, GABA functions as an inhibitory neurotransmitter in the brain that directly affects the personality and the stress managemen
