1. Selecting alternative sterile and non-sterile substrates for mycorrhizal inoculant production
ABSTRACT Alternative substrates were evaluated for mycorrhizal inoculants production considering the beneficial effects of arbuscular mycorrhizal fungi (AMF) for plants and environment. The first step of the experiment aimed at evaluating the potential of substrates produced from sugarcane bagasse (SB), coconut fibre (CF) and urban waste compost (UWC) to pro

2. Reaction of weeds, found in vegetable production areas, to root-knot nematodes Meloidogyne incognita and M. enterolobii
RESUMO Os nematoides-das-galhas causam muitos prejuízos às lavouras de hortaliças no Brasil, além de possuírem grande gama de plantas hospedeiras, incluindo as plantas daninhas. Estas podem manter o inóculo ou mesmo favorecer a multiplicação desses nematoides. Diante do exposto, objetivou-se com esse trabalho avaliar a reação de espécies seleciona

3. Beneficial effects of bio-controlling agent Bacillus cereus IB311 on the agricultural crop production and its biomass optimization through response surface methodology
ABSTRACT Disease in agricultural field is a big problem that causes a massive loss in production. In this present investigation, we have reported a soil-borne bacterium Bacillus cereus IB311 which is antagonistic to plant pathogens (Pseudomonas syringae and Agrobacterium tumefaciens), and could make a substantial contribution to the prevention of plant disea

4. Cellulase activity and dissolved organic carbon release from lignocellulose macrophyte-derived in four trophic conditions
Abstract Considering the importance of lignocellulose macrophyte-derived for the energy flux in aquatic ecosystems and the nutrient concentrations as a function of force which influences the decomposition process, this study aims to relate the enzymatic activity and lignocellulose hydrolysis in different trophic statuses. Water samples and two macrophyte spe

5. Optimization Medium Composition for Vitamin K2 by Flavobacterium sp. using Response Surface Methodology and Addition of Arachis hypogaea
ABSTRACT The purpose of this research was to enhance the production of vitamin K2 by fermentation optimization and Arachis hypogaea supplementation in Flavobacterium sp. mutant SP-L-01. Optimized culture condition were as follows: 6-days shake-flask culture at 37oC with initial pH value 7.0 ± 0.2, shaking speed in 120 r/min and medium volume of 30 mL with 2

6. Improved 1-Deoxynojirimycin (DNJ) production in mulberry leaves fermented by microorganism
DNJ, an inhibitor of α-glucosidase, is used to suppress the elevation of postprandial hyperglycemia. In this study, we focus on screening an appropriate microorganism for performing fermentation to improve DNJ content in mulberry leaf. Results showed that Ganoderma lucidum was selected from 8 species and shown to be the most effective in improvement of DNJ

7. Enhancement of chitosanase production by cell immobilization of Gongronella sp. JG
Chitosanase production of Gongronella sp. JG cells immobilized in calcium alginate gel and polyurethane foam was compared with that of the free cells, there was a 60% increase in the enzyme yield (2429 U/L) compared to the highest yield obtained from free cells (1513 U/L). The optimal immobilization parameters (concentrations of sodium alginate, calcium chlo

8. Avaliação da eficácia da desinfecção de instrumentos usados durante o período transoperatório do tratamento endodôntico / Evaluation of the desinfection efficacy of instruments used during the transoperatory period in endodontic treatment
This investigation aimed to evaluate the antimicrobial efficacy of disinfectant agents used to maintain the disinfection of endodontic instruments during the transoperatory period in endodontic treatment. The antimicrobial activity of disinfectants isopropyl alcohol, acetone and peracetic acid were evaluated upon planktonic micro-organisms by time kill assay

9. The potential of bamboo in the design of polymer composites
Bamboo is an alternative sustainable material for use in product design and has been incorporated into the concepts of eco-design. Here, we investigated the mechanical properties and morphologies of low density polyethylene (LDPE)/bamboo flour (BF) composites that were modified with polyethylene-graft-maleic anhydride (PE-g-MA) and glycerol. Scanning electro

10. Growth inhibition of Staphylococcus aureus and escherichia coli strains by neutralizing IgY antibodies from ostrich egg yolk
Ostrich raising around the world have some key factors and farming profit depend largely on information and ability of farmers to rear these animals. Non fertilized eggs from ostriches are discharged in the reproduction season. Staphylococcus aureus and Escherichia coli are microorganisms involved in animal and human diseases. In order to optimize the use of

11. Isolation and characterization of a Pichia anomala strain: a promising candidate for bioethanol production
A yeast strain designated as Y-1 was isolated and characterized from wine yeast ("Jiuqu"). Based on the morphological and biochemical results, along with the rDNA internal transcribed spacer region (ITS), Y-1 was identified to be a Pichia anomala strain. Y-1 is an ethanol-tolerant strain, enduring ethanol concentrations of up to 14 %. Y-1 growth medium condi

12. Ethambutol resistance of indigenous Mycobacterium tuberculosis isolated from human patients
The present study was conducted to find out the ethambutol resistance pattern of indigenous isolates of Mycobacterium tuberculosis from Tuberculosis diagnosed human patients. A total of 172 specimens were collected from six different sources and comprised of 84.9% sputum, 10.5% pus and 4.7% bronchial washings. There were 70.9% males and 29.1% females with 84
