(
Elsevier B.V.
, 2011 , Article)
The present study describes the phytochemical profile and the protective effects of Ceratonia siliqua pods essential oil (CsEO), a food and medicinal plant widely distributed in Tunisia. Twenty five different components ...
Isolation of entomopathogenic Bacillus from a biodynamic olive farm and their pathogenicity to lepidopteran and coleopteran insect pests
(
Elsevier Ltd.
, 2012 , Article)
The occurrence of Bacillus entomopathogenic bacteria on a Tunisian biodynamic farm was determined by examining 75 samples from olive tree (Olea europaea L.) habitats. A total of 40 Bacillus isolates were characterized ...
Antioxidant constituents from Lawsonia inermis leaves: Isolation, structure elucidation and antioxidative capacity
(
Elsevier Ltd.
, 2011 , Article)
The antioxidant potential of different fractions of Lawsonia inermis (Lythraceae) was investigated. The n-butanolic fraction showed the highest yield of extraction; it also exhibited a strong antioxidant activity in the ...
Involvement of oxidative stress and growth at high cell density in the viable but nonculturable state of Photorhabdus temperata ssp. temperata strain K122
(
Elsevier Ltd.
, 2010 , Article)
Photorhabdus temperata ssp. temperata strain K122 represents a promising source of bioinsecticide. When cultured in an optimized medium, P. temperata exhibited restricted survival in terms of colony-forming ability on solid ...
Amino acids Y229 and F603 are involved in Bacillus thuringiensis Cry1Ac delta-endotoxin stability and toxicity
(
Blackwell Publishing
, 2012 , Article)
Bacillus thuringiensis Cry1Ac toxin shares structurally five conserved blocs with the other δ-endotoxins. To study the role of some amino acids belonging to these regions, two mutations, Y(229) P and F(603) S, were introduced ...
Evidence of a Role for Aerobic Bacteria in High Magnesium Carbonate Formation in the Evaporitic Environment of Dohat Faishakh Sabkha in Qatar
(
Frontiers Media
, 2017 , Article)
Dolomite (MgCa(CO3)2) is an important petroleum reservoir rock mineral common in ancient sedimentary rocks which is infrequently found in modern environments. The mechanism of dolomite formation remains poorly understood, ...
Considering the Specific Impact of Harsh Conditions and Oil Weathering on Diversity, Adaptation, and Activity of Hydrocarbon-Degrading Bacteria in Strategies of Bioremediation of Harsh Oily-Polluted Soils
(
Hindawi Publishing Corporation
, 2017 , Article)
Weathering processes change properties and composition of spilled oil, representing the main reason of failure of bioaugmentation strategies. Our purpose was to investigate the metabolic adaptation of hydrocarbon-degrading ...
Characterization of bioactive compounds and ameliorative effects of Ceratonia siliqua leaf extract against CCl4 induced hepatic oxidative damage and renal failure in rats
(
Elsevier Ltd.
, 2011 , Article)
Ceratonia siliqua is a typical Mediterranean plant, mainly used in food and Tunisian traditional folk medicine. Among the tested extracts, the ethyl acetate fraction (EACs) exhibited the highest total phenolic and flavonoids ...
