1. Pumilacidins A-E from Sediment-Derived Bacterium Bacillus sp. 4040 an Their Antimicrobial Activity Evaluation
Marine strains of Bacillus are known to produce secondary metabolites different from that accumulated by their terrestrial counterparts, for example, lipopeptides such as surfactins, iturins and fengycins, which exhibit a variety of biological activities. Another important class of lipopeptides are pumilacidins, identified specially from Bacillus pumilus str

2. OPTIMIZATION OF BIOFLOCCULANT PRODUCTION BY Bacillus spp. FROM SUGARCANE CROP SOIL OR FROM SLUDGE OF THE AGROINDUSTRIAL EFFLUENT
Abstract Biological flocculants are advantageous due to their biodegradability and safety to living beings. In this work, four bacterial strains, isolated from sugarcane cropped soil (Bacillus megaterium LBPMA-APFSG3Isox and B. toyonensis LBPMA-ACOPR1.Isox) and sludge of an agroindustrial effluent (B. pumilus LBPMA-BLD07 and B. thuringiensis LBPMA-EFIII), we

3. Nitric oxide inhibitory and anti-Bacillus activity of phenolic compounds and plant extracts from Mesua species
ABSTRACT Species from the genus Mesua, Calophyllaceae, are rich source for phenolic compounds such as coumarin xanthone, and benzophenone derivatives. An investigation on the potential biologically active phenolic compounds 1–5 and crude extracts from the stem bark of Mesua hexapetala (Hook. f.) P.S. Ashton and Mesua beccariana (Baill.) Kosterm. for nitric

4. 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

5. BACTÉRIAS ENDOFÍTICAS COMO BIOINOCULANTES PARA MUDAS MICROPROPAGADAS DE BANANEIRA
RESUMO A utilização de biofertilizantes ou inoculantes microbianos capazes de promover o crescimento e incrementar a produtividade das plantas têm sido aceita como alternativa a redução do uso de adubos químicos. Diante do exposto objetivou-se avaliar o o crescimento e qualidade de mudas micropropagadas de bananeira ‘Prata Anã’ após a bioinocula

6. Genetic diversity and population densities of endophytic Bacillus spp. in yam plants
ABSTRACT This study was conducted as a first step in exploiting endophytic bacteria to improve yam production. Little information is available on population densities and genetic diversity of endophytic bacteria in yam cultivated in tropical regions. This study demonstrated that higher densities of total endophytic bacteria and Bacillus occur in the interior

7. Avaliação in vitro da adsorção de aflatoxina B1 por produtos comerciais utilizados na alimentação animal
RESUMO: Objetivou-se avaliar a capacidade de adsorção in vitro de aflatoxina B1 (AFB1) por produtos comerciais utilizados na alimentação animal. Muitas pesquisas estão sendo realizadas para a descontaminação de AFB1 em alimentos. Os produtos comerciais utilizados frequentemente na alimentação de peixes, disponíveis na forma de probióticos, são fo

8. PREPARATION AND CHARACTERIZATION OF IMMOBILIZED SPORES WITH LACCASE ACTIVITY FROM Bacillus pumilus W3 ON DEAE-CELLULOSE AND THEIR APPLICATION IN DYE DECOLORIZATION
Abstract In order to obtain a more stable and reusable immobilized spore laccase for dye decolorization, the spores from Bacillus pumilus W3 were immobilized on diethylaminoethyl cellulose (DEAE-cellulose). Free and immobilized spore laccase retained 34.38% and 46.11% of their initial activity, respectively, after 10 days incubation at pH 9.0. Their residual

9. SELEÇÃO POLIFÁSICA DE MICRORGANISMOS PRODUTORES DE POLIHIDROXIALCANOATOS
Polyhydroxyalkanoates (PHAs) are fully biodegradable biopolyesters produced by many prokaryotes and accumulated as insoluble cytoplasmatic inclusions. The detection of these intracellular granule is usually provided using lipofilic azodyes, which are not specific. Another way to screen PHA-producing bacteria is through culture-independent molecular technique

11. Aerobic cyanide degradation by bacterial isolates from cassava factory wastewater
Ten bacterial strains that utilize cyanide (CN) as a nitrogen source were isolated from cassava factory wastewater after enrichment in a liquid media containing sodium cyanide (1 mM) and glucose (0.2% w/v). The strains could tolerate and grow in cyanide concentrations of up to 5 mM. Increased cyanide levels in the media caused an extension of lag phase in

12. Thermophilic bacteria in Moroccan hot springs, salt marshes and desert soils
The diversity of thermophilic bacteria was investigated in four hot springs, three salt marshes and 12 desert sites in Morocco. Two hundred and forty (240) thermophilic bacteria were recovered, identified and characterized. All isolates were Gram positive, rod-shaped, spore forming and halotolerant. Based on BOXA1R-PCR and 16S rRNA gene sequencing, the recov
