Occurrence of begomoviruses in cotton-vegetable agro ecosystem in India
Begomoviruses are the important pathogens of variety of crop plants and are responsible for causing huge economic losses. It is assumed that cotton vegetable agro eco system plays a vital role in the complex etiology of the diseases caused by begomoviruses. Therefore, the present work was planned to study the relationship among begomoviruses infecting cotton, chilli, radish, tomato and papaya. For this purpose, the...

Evaluation of hygienic-sanitary quality of honey from Apis mellifera L. obtained in semi-arid region of PiauÃ, Brazil
This study aimed to evaluate the quality of honey from Apis mellifera L. obtained in Piauí, Brazil. The completely randomized design (CRD) was used in the experiments. Two treatments of honey were prepared: one from beekeepers that use Extraction Units for Bee Products (EUBP) with Best practices for beekeeping (T1), and another one from those which use EUBP without the best practices (T2). Parameters analyzed...

Cultivation and nutritional studies of an edible mushroom from North Brazil
The vertical mycelial growth to investigate the feasibility of Pleurotus ostreatoroseus DPUA 1720 production in lignocellulosic Amazonic residues was evaluated. Mycelial development was carried out in cupuaçu exocarp (Theobroma grandiflorum Willd Former Spreng Schum), açai seed (Euterpe oleracea) and sawdust as substrates. Each residue was supplemented with rice bran, crown and pineapple peel. The average...

Effect of processing steps and storage on microbiota and volatile amines content of salted semi preserved cuttlefish (Sepia officinalis)
Microbial and volatile amines changes during processing steps and storage in optimal and abuse temperatures of semipreserved cuttlefish and their efficiency for quality was investigated. After osmotic treatment the initial microbial contamination and the total volatile basic nitrogen (TVBN) decreased sharply. The microbiota changed to Gram positive bacteria in which species of Bacillus and Staphylococcus were dominant....

Bacteriophage based self-assembled monolayer (SAM) on gold surface used for detection of Escherichia coli by electrochemical analysis
Bacteriophages (or phages) are parasites that infect specific bacteria. This host-selectivity can be useful to identify bacterial contaminants in food, water, environment etc. In the present study, phage was isolated from stagnant water and cultivated by overlay method against host bacteria that is E. coli. Phage titer was calculated to be 107 pfu/ml using 10-fold dilutions. Plaque reaction activity was observed...

Evaluation of antibacterial activities of Barleria Prionitis Linn
In the present study, 1 g/ml each of Barleria prionitis leaves (BPL) and B. prionitis stem (BPS) were extracted from different solvents like petroleum ether, chloroform ethyl acetate and methanol. Ethyl acetate extract of BPL showed maximum inhibition zone on Gram positive Bacillus pumilus (9.83 mm) and methanol extract of BPS showed minimum inhibition zone on Gram negative Escherichia coli (0.16 mm). Petroleum ether...

Comparison of two storage conditions of Candida albicans for DNA extraction and analysis
The major human fungal pathogens are species from the genus Candida, especially Candida albicans. C. albicans sample preservation from human source is essential for clinical purposes and epidemiologic studies; however, little is known about its conservation for DNA extraction and analysis. Therefore, the aim of this study was to evaluate and compare two storage conditions of C. albicans for performing DNA extraction and...
