Assessment of the antioxidant and antibacterial activities of different olive processing wastewaters
Olive processing wastewaters (OPW), namely olive mill wastewater (OMW) and table-olive wastewaters (TOW) were evaluated for their antibacterial activity against five Gram-positive and two Gram-negative bacteria using the standard disc diffusion and thin layer chromatography (TLC)-bioautography assays. Disc diffusion screening and bioautography of OMW were compared to the phenolic extracts of ta...
The present work was designed to study the antioxidant activity and to identify the main active components of the essential oil of ajowan (Trachyspermum copticum) fruit. GC and GC-MS analyses of the essential oil showed the presence of eight compounds. The main constituents of the oil were thymol (43.7%), p-cymene (26.8%), and γ-terpinene (24.9%). The antioxidant and free radical scavenging act...
The antibacterial activity of immune haemolymph Galleria mellonella directed against Escherichia coli D31 was destroyed by Pseudomonas aeruginosa crude proteolytic fraction. This was demonstrated by diffusion well assay and acid gel electrophoresis and subsequent bioautography. On the contrary, lysozyme activity appeared to be insensitive to extracellular proteases of P. aeruginosa when activit...
S treptococcus mutans (Gram-positive) and higella dysenteriae (Gram-negative) are two types of pathogen bacteria. The use synthetic antibiotics against both bacteria is known to impact the bacteria's resistance. E. spinosum from Tasikmalaya a potential macroalgae as source an antibacterial compound for research aims determine metabolite s pinosum originated S. . was conducted through several st...

In this study antimicrobial effects of Salivia mirzayanii and Saliva atropatana were evaluated against six gram-positive and gram-negative bacteria by immersion bioautography, cylinder plate and tube dilution methods separately. In bioautography method, essential oils of Salvia mirzayanii and Salvia atropatana were separated on silicagel TLC plates by toluene-ethyl acetate (93-7). In cylander p...

Objective: The aims of the present study were to screen actinobacteria with high potential ability produce secondary metabolites that have inhibitory activity against plant pathogenic fungi, Magnaporthe oryzae. Production was analysis by thin-layer chromatography and bioautography assay.
 Methods: Screening selection Streptomyces sp. morphological, cultural, physiological, biochemical char...
Fruits and vegetables are an essential part of a healthy diet, providing humans with vitamins, phytonutrients, minerals. They significantly vulnerable, however, to post-harvest diseases caused by numerous fungal bacterial pathogens. These pathogens can cause significant quantitative qualitative losses from harvest consumption during the handling storage processes. Chemical fungicides commonly u...
