Cyanide removal from aqueous environment by resting cells and PTFE immobilized cells of Sphingobacterium spp.

Microbial detoxification of cyanide offered an inexpensive, safe, and viable alternative to physiochemical processes for the treatment of cyanide in industrial effluents or contaminated sites. This study involved isolation of novel strain with high resistance against cyanide toxicity and able to degrade the cyanide radical. The strain was isolated from rocky area and identified as Sphingobacterium multivorium using 16S ribosomal RNA.

Bioprospection of Antiviral and Antitumor Compounds from Some Marine Algae from Egyptian Shores.

Background: The marine algae are considered a diverse source of bioactive compounds. Many active compounds have been isolated from algae and show good biological activities.

Materials And Methods: The aim of this study is to detect the antiviral and anticancer activities in some extracts of marine algae.

Drinking water quality and public health in Southwestern Saudi Arabia: The need for a national monitoring program.

Aim Of The Study: The aim was to investigate the bacteriological quality of drinking water, and explore the factors involved in the knowledge of the public about the quality of drinking water in Najran region, Saudi Arabia.

Study Design: A cross-sectional descriptive study.

Materials And Methods: A total of 160 water samples were collected.

Antiquorum from freshwater zoosporic isolated fungi: maximization of some ameliorative factors.

Many bacteria detect their critical cell numbers through a mechanism known as quorum sensing (QS). Acyl homoserine lactones (AHLs) mediated QS systems have been shown to operate in important human pathogens. The aim of this study was to evaluate the inhibitory effect generated by zoosporic freshwater fungi on AHLs production.

Synthesis and antimicrobial evaluation of 1-(benzofuran-2-yl)-4-nitro-3-arylbutan-1-ones and 3-(benzofuran-2-yl)-4,5-dihydro-5-aryl-1-[4-(aryl)-1,3-thiazol-2-yl]-1H-pyrazoles.

2-Acetylbenzofuran 1 on treatment with substituted aldehydes affords the corresponding chalcones 2a-c. Treatment of the chalcones with nitromethane under Michael addition condition furnished the corresponding Michael adducts 3a-c. Cyclocondensation of the chalcones 2a and 2b with thiosemicarbazide under basic refluxing conditions gave 3-(benzofuran-2-yl)-5-(4-aryl)-4,5-dihydropyrazole-1-carbothioamides 4a,b.

Convenient synthesis and antimicrobial activity of new 3-substituted 5-(benzofuran-2-yl)-pyrazole derivatives.

The reaction of ethyl 4-(benzofuran-2-yl)-2,4-dioxobutanoate 2 with two moles of hydrazine hydrate afforded 5-(benzofuran-2-yl)-1H-pyrazole-3-carbohydrazide 4a, while its reaction with equimolar amount of phenylhydrazine gave ester 3b which then converted to 5-(benzofuran-2-yl)-1-phenyl-1H-pyrazole-3-carbohydrazide 4b. Various new compounds such as imides 5 and 6, acyl hydrazones 7 and 8, bi-pyrazoles 9-12, and 1,3-thiazole derivatives 14 and 15 were prepared from carbohydrazide derivatives 4a, b. The new compounds are tested for their antimicrobial activity.
