1. Conversion of ammonium to nitrate and abundance of ammonium-oxidizing-microorganism in Tropical soils with nitrification inhibitor
ABSTRACT The use of nitrification inhibitors (NIs; dicyandiamide - DCD) is an alternative to reduce oxidation of ammonium (NH4+-N) to nitrate (NO3–-N) in the soil, reducing NO3–-N losses from fertilization practices. Based on the hypothesis that DCD reduces conversion of NH4+-N to NO3–-N in tropical soils and inhibits ammonia oxidizing microorganisms (

2. Degradation of monoaromatics by Bacillus pumilus MVSV3
ABSTRACT Monoaromatics, such as benzene, toluene, ethylbenzene and xylene (BTEX), are simple aromatic compound that are highly toxic due to their high solubility nature. Many chemical and physical methods for their degradation and breakup into nontoxic products are available, but still use of microorganism is preferred over these processes. In this present s

3. Use of Organic Compost Containing Waste from Small Ruminants in Corn Production
ABSTRACT Composting is a useful way of transforming livestock waste into organic fertilizer, which is proven to increase soil nutrient levels, and thus crop yield. Remains from production and slaughter of small ruminants can become a source of important elements for plant growth, such as N, after microorganism-driven decomposition.The aim of this investigati

4. Composition of Poultry Litter in Southern Brazil
ABSTRACT Determining the chemical composition of poultry litter is important in order to apply this waste as soil fertilizer without causing negative environmental impacts. The aim of this study was to evaluate the average and variability of some chemical parameters of 165 samples of poultry litter produced from confined animal production facilities located

5. Molecular Identification of Trichoderma spp. in Garlic and Onion Fields and In Vitro Antagonism Trials on Sclerotium cepivorum
ABSTRACT Trichoderma species are non-pathogenic microorganisms that protect against fungal diseases and contribute to increased crop yields. However, not all Trichoderma species have the same effects on crop or a pathogen, whereby the characterization and identification of strains at the species level is the first step in the use of a microorganism. The aim

6. Assessment of cellulolytic microorganisms in soils of Nevados Park, Colombia
A systematized survey was conducted to find soil-borne microbes that degrade cellulose in soils from unique ecosystems, such as the Superpáramo, Páramo, and the High Andean Forest in the Nevados National Natural Park (NNNP), Colombia. These high mountain ecosystems represent extreme environments, such as high levels of solar radiation, low atmospheric pres

7. Bioprocessing of some agro-industrial residues for endoglucanase production by the new subsp.; Streptomyces albogriseolus subsp. cellulolyticus strain NEAE-J
The use of low cost agro-industrial residues for the production of industrial enzymes is one of the ways to reduce significantly production costs. Cellulase producing actinomycetes were isolated from soil and decayed agricultural wastes. Among them, a potential culture, strain NEAE-J, was selected and identified on the basis of morphological, cultural, physi

8. Análise transcricional dos genes envolvidos na nodulação e predição in silico de microRNAs em raízes de soja inoculadas com a estirpe CPAC 15 de Bradyrhizobium japonicum
A fixação biológica de nitrogênio é um processo de grande importância para a cultura da soja, capaz de suprir toda sua demanda de nitrogênio, necessário para a síntese de biomoléculas. Entretanto, para que os nódulos sejam formados todas as etapas devem ser estreitamente coordenadas por uma série de sinais moleculares entre a planta e a bactéria

9. Desenvolvimento de inoculante microbiano promotor de crescimento de Schizolobium parahyba (Vell.) Blake
No contexto do desmatamento ocorrido ao longo dos anos no Estado do Paraná com a perda drástica da cobertura vegetal nativa e a crescente demanda por projetos de recuperação da mata ciliar, o estudo do Schizolobium parahyba (guapuruvú) para avaliar o seu potencial como fonte de madeira e de cobertura vegetal incrementar seu uso por ser uma espécie arb�

10. Production of peptide antibiotics by Bacillus sp: GU 057 indigenously isolated from saline soil
A total of 112 soil samples were taken from differents areas of district D.I.Khan and Kohat (KPK) Pakistan and screened for production of antibiotics against the Micrococcus luteus and Staphylococcus aureus. Widest zone of inhibition (18mm) was produced by microorganism isolated from saline soil. The strain was later identified as Bacillus GU057 by standard

11. Production of α-amylase from Streptomyces sp. SLBA-08 strain using agro-industrial by-products
Approximately 1.5 trillion tons are the estimated yearly biomass production, making it an essentially unlimited source of raw material for environmentally friendly and biocompatible products transformed by microorganism, specially fungi and actinomycetes. Several lignocellulosic residues, such as sisal waste and sugarcane bagasse contain starch in their stru
