Alcaligenes latus, isolated from industrial effluent, was able to grow in mineral salts medium with 50 ppm (0.15 mM) of H-acid as a sole source of carbon. Immobilization of Alcaligenes latus in Ca-alginate and polyurethane foam resulted in cells embedded in the matrices. When free cells and immobilized cells were used for biodegradation studies at concentration ranging from 100 ppm (0.3 mM) to ...

The composition of a chloroform seed extract of C. papaya was determined by GC-MS. Nineteen compounds were identified, with oleic (45.97%), palmitic (24.1%) and stearic (8.52%) acids being the main components. The insecticidal and insectistatic activities of the extract and the three main constituents were tested. Larval duration increased by 3.4 d and 2.5 d when the extract was used at 16,000 ...

A field experiment was conducted during 2006-2007 and 2007-2008 seasons at Herbal garden, Rajendranagar, Hyderabad, India to study the influence of exogenous application of CPPU and GA yield, 3 fruit quality characters and seedlessness in watermelon. The experiment consists of 12 treatments (CPPU-50 ppm (T ), CPPU-100 ppm (T2), CPPU-200 ppm (T3), GA -100 ppm(T ), GA -200 ppm(T ), CPPU 50 ppm + ...

Phthalates are common plasticizers used in pPVC (plasticized polyvinyl chloride) products. Phthalates are commonly found in the child rearing products (for teething, toys etc.), blood bags, dialysis tubing, paints, lacquers, cosmetics, coatings of capsules etc. The present study was conducted to explore the potential of new microbial strains for the biodegradation and biotransformation of phtha...

a pot experiment was conducted to evaluate the effect of foliar spray of salicylic acid (0, 50, 100 ppm), ascorbic acid (0, 100, 200 ppm) and thiamine (0, 50, 100 ppm) on vegetative growth, flowering and photosynthetic pigments of marigold (calendula officinalis l.) plants at greenhouse of sb university of kerman, iran. results showed that application of salicylic acid and thiamine increased nu...

The oxidation products of selenomethionine (SeMet) have been studied via experimental (77)Se NMR and theoretical (77)Se chemical shifts. Four signals are observed: a diastereomeric pair of selenoxides at 840 ppm and two unidentified resonances at 703 and 716 ppm. Theoretical DeltaG and chemical shifts suggest the 703 and 716 ppm resonances correspond to hypervalent selenium heterocycles, called...

Pollution by pathogenic microorganisms in food materials is capable of resulting in various diseases and increased resistance against various types of antimicrobial. Therefore, new more effective antibiotics are needed to overcome the multi-drug resistant bacteria. This study was aimed to examine the effectiveness of extracted antibacterial compound from hydroid Aglaophenia cupressina Lamoureou...

BACKGROUND Taking into account the improvement in insecticidal activity by the inclusion of fluorine in the hydrazone moiety, the authors synthesized new 4-fluorobenzoic acid hydrazides and 3-acetyl-2,5-disubstituted-2,3-dihydro-1,3,4-oxadiazoles, substituting a phenyl group or a heteroaryl ring carrying one or two atoms of F, Cl and Br, and investigated their biting deterrent and larvicidal ac...
