We demonstrate new method for the synthesis of gold and silver nanoparticles from pineapple extract. Furthermore, we have studied interactions between nanoparticles (gold and silver) with aminoglycosides such as Kanamycin A, Neomycin. Both nanoparticles were prepared by reducing AuCl4 and AgNO3 using pineapple extract, kanamycin A and neomycin as both reducing and stabilizing agents respectivel...

SIMILAR MEALYBUGS: There are several mealybugs that are reported as occurring on orchids, and in Florida the most commonly encountered mealybugs on orchids are: pineapple mealybug (Dysmicoccus brevipes), longtailed mealybug (Pseudococcus longispinus), Jack Beardsley mealybug (Pseudococcus jackbeardsleyi), orchid mealybug (Pseudococcus microcirculus) and the obscure mealybug (Pseudococcus viburn...

E&acts of pineapple stem tissue constitute the most potent known source of indoleacetic acid oxidase, despite the presence of an inhibitor which is difficult to remove without simultaneously removing some other factor necessary for maximal activity (I). Dialysis invariably lowers the enzyme activity as compared with photolysis, and even prolonged photolysis is never completely effective in remo...

Several purification and characterization studics have been reported en enzymes from such sources as pineapple,"} rnushroom,2) hen oviduct,3) snails,barley,S] and from microbial seurces su ¢h as these of alkatophilic Bacillu.s speciese) and Aspergiltus niger,7'S) However, the use ef fimannosidase in transmannosidation studies have not been reported. The enzymatic method for the synthesis of gly...

This study investigated the effect of injecting pineapple concentrate and honey into low marbled beef in order to enhance its sensory qualities, particularly tenderness and flavor, without compromising its fresh appearance. Beef loin was injected with a solution of 6.0% pineapple concentrate, 2.5% honey, 0.5% monosodium L-glutamate, 0.5% phosphate, and 0.3% salt (w/w) to 120% (w/w) of initial m...

Brazil produces over than 70,000 ha of pineapple, being the world leader in pineapple production, and Minas Gerais State alone produces over than 600 kt/y. The pineapple is the marketable plant part, which represents only 23 % of the plant itself, and the remaining plant, stem, leaves, bark and crown, being considered an agroindustrial residue. This residue contains great amount of bromelain, a...

Heterogeneity in fruit quality (size and taste) is a major problem in pineapple production chains. The possibilities were investigated of reducing the heterogeneity in pineapple in the field by pruning slips on selected plants, in order to promote the fruit growth on these plants. Slips are side shoots that develop just below the pineapple fruit during fruit development. Two on-farm experiments...

Fruit color and odor are the main features regulating the rate of fruit predation and dispersal. The aim of this study was to analyze the effect of odor and color on fruit predators and dispersers. The present study was conducted in a 30ha area of secondary forest in Southeastern Atlantic Brazil. This area was divided into two transects, in which four points were marked with a 30m distance from...

BACKGROUND The aim of the present study was to evaluate the physicochemical and antioxidant properties of Malaysian monofloral honey samples-acacia, pineapple and borneo honey-and compare them with tualang honey. Acacia and pineapple honey are produced by Apis mellifera bees while borneo and tualang honey are produced by Apis cerana and Apis dorsata bees, respectively. METHODS The physical pa...
