Abstract:

The emergence of new infectious diseases, resurgence of several infections that appeared to have been controlled and the increase in bacterial resistance has led to the need for studies directed towards the development of new antimicrobials. Considering the challenge of obtaining new molecules with antimicrobial properties from microorganisms, identifying antimicrobials from other natural sources is of great importance. The phytochemical and antimicrobial activity of ethanolic leaf extracts of <em>Calotropis procera</em>, <em>Momordica charantia</em> and <em>Allium ascalonicum</em> was investi

In recent decades, an increase in resistance of bacteria and fungi to antimicrobials has been observed. Therefore, have each other investigated the antimicrobial potential of plants with medicinal properties. In this context, the Amazon has a high variability of plants with potentially active compounds. Thus, the present study aimed to evaluate the antimicrobial activity of ethanol extracts from Amazonian medicinal plants. Leaves and stems of 19 plant species were dried, crushed and extracted by cold maceration with ethanol. The extracts were dried and solubilized at a concentration of 100 mg

Part I: The purpose of the investigation was to develop the extraction process that was simple, practical and giving high yield. The maceration of dried powder of Garcinia mangostana fruit husk with ethyl acetate gave yellow crystalline powder of mangostin. The yield was calculated as 7.47%. The identification of the Garcinia mangostanahusk extract was carried out by thin-layer chromatography (TLC) and differential scanning calorimetry. The TLC of mangostin was done by using the alumina sheet and ethyl acetate: hexane (3:1) as mobile phase. The Rf value as compared with standard mangostin was

Abstract:

Extract from mangosteen pericarp has demonstrated various pharmacological activities including anti-bacterial, anti-inflammatory and anti-fungal. It may have potential for the treatment of periodontal disease, which is a chronic inflammatory disease caused by anaerobic bacteria. The aim of this study was 1) to investigate the toxicity of mangosteen extract to human gingival fibroblast, 2) to examine the anti-bacterial activity of the extract against periodontopathic bacteria including P. gingivalis and A. actinomycetemcomitans, and 3) to examine the inhibitory effect of the extract on PGE[subs

Original objectives . 1. Test anti-fungal gene products for activity against Uncinula necator, Aspergillus niger, Rhizopus stolonifer and Botrytis cinerea. 2. For Agrobacterium transformation, design appropriate vectors with gene combinations. 3. Use biolistic bombardment and Agrobacterium for transformation of important cultivars. 4. Characterize gene expression in transformants, as well as level of powdery mildew and Botrytis resistance in foliage of transformed plants. Background The production of new grape cultivars by conventional breeding is a complex and time-consuming process. Transfer

Abstract:

This research was aimed to develop an active film from chitosan film incorporated with green tea extract to enhance antioxidant and antimicrobial properties in order to be used for food shelf life extension. The experiments were divided into 3 parts. Firstly, chitosan-based film preparation and modification were determined. The results suggested that the optimum chitosan films could be prepared from 2% chitosan in 1% acetic acid. However, the chitosan film was brittle and had low flexibility. Mechanical property of chitosan film was modified by adding different concentrations of glycerol, as a

Abstract:

Fusarium oxysporum spp. causes Panama disease in bananas and crown and root rot in an array of vegetables and field crops, but increased regulations have restricted the use of many conventional chemical pesticides, and there are a limited number of commercially available products effective against them. The soil microbiome represents a largely untapped reservoir of secondary metabolites that can potentially antagonize fungal pathogens. However, most soil bacteria cannot be cultivated using conventional techniques and therefore most of these compounds remain unexplored. The overall goal of this
