Leaves of Pistacia lentiscus were collected from two Algerian sites in the mountains and littoral Tizi-Ouzou region. The harvest was conducted four consecutive seasons on same selected set trees. Essential oils (EOs) extracted by hydrodistillation; then, they analyzed gas chromatography coupled mass spectrometry (GC-MS). Forty-seven constituents could be detected quantified, including α-pinene (2-13%), β-caryophyllene (8-25%), β-myrcene (0.3-19%), bornyl acetate (0.8-7%), δ-cadinene (3-8%),...
Black Aspergilli represent one of the most important fungal resources primary and secondary metabolites for biotechnological industry. Having several black sequenced genomes should allow targeting production certain with bioactive properties.In this study, we report draft genome a Aspergilli, A. tubingensis G131, isolated from French Mediterranean vineyard. This 35 Mb includes 10,994 predicted genes. A genomic-based discovery identifies 80 biosynthetic gene clusters. Genomic sequences these...
Gabon has a rich flora, many species of which are used in traditional medicine. However, little research been carried out on this wealth. An ethnopharmacological survey the Fang language was among practitioners to collect antimicrobial medicinal plants. Phytochemical profiling ethanolic and methanolic extracts from
Ribosome biogenesis requires more than 200 trans-acting factors to achieve the correct production of two mature ribosomal subunits. Here, we have identified Efg1 as a novel, nucleolar ribosome factor in Saccharomyces cerevisiae that is directly linked surveillance pre-40S particles. Depletion impairs early pre-rRNA processing, leading strong decrease 18S rRNA and 40S subunit levels an accumulation aberrant 23S rRNA. Using bait, revealed novel degradation pathway Co-immunoprecipitation...
Flavonoids have been documented to good antioxidant activities in vitro. In recent years, reports on the of flavone C-glycosides, a subclass flavonoids, attracted great attention. Despite wealth information this subject, correlation between structure and function is not well understood. work, relationship activity 12 C-glycosides extracted from aerial part winter linseed (Linum usitatissimum L.) was studied fill current gaps. Orientin, isoorientin, vitexin, isovitexin, swertisin,...
Ochratoxin A (OTA) is a mycotoxin produced by several species of Aspergillus and Penicillium that contaminate food feed raw materials. To reduce OTA contamination, we first tested in vitro, actinobacterial strains as potential biocontrol agents afterward, through physical decontamination method using activated carbon fibers (ACFs). Actinobacterial were screened for their ability to solid co-culture with A. carbonarius, which the major OTA-producing European vineyards. Four showed high...
Erismadelphus exsul Mildbr bark is widely used in Gabonese folk medicine. However, little known about the active compounds associated with its biological activities. In present study, phytochemical profiling of ethanolic extract was performed using a de-replication strategy by coupling HPLC-ESI-Q/TOF molecular network approach. Eight families natural were putatively identified, including cyclopeptide alkaloids, esterified amino acids, isoflavonoid- and flavonoid-type polyphenols,...
Baillonella toxisperma is a medicinal plant used in northern Gabon to treat microbial diseases. It well-known by local populations, but very few studies have focused on the molecules responsible for antibacterial activities of B. toxisperma. This study proposes dereplication strategy based molecular networking generated from HPLC-ESI-Q/TOF data, allowing investigation activity From this strategy, eighteen compounds were putatively identified. All these belonged mainly five families natural...
In eukaryotes, ribosome biogenesis is a process of major interest that requires more than 200 factors acting coordinately in time and space. Using genetic proteomic studies, most the components have now been identified. Based on its nucleolar localization, we characterized protein encoded by open reading frame YGR251W, renamed Nop19p as playing an essential role biogenesis. Depletion yeast impairs pre-rRNA processing at sites A₀, A₁ A₂, leading to strong decrease 18S rRNA 40S subunit levels....
The main objective of this work is the development new active films based on yeast cell wall obtained by high-pressure homogenization (YCW-H) supplemented with naphtho-γ-pyrone (CL-NGP) extract, which a bioactive compound produced Aspergillus tubingensis G131 great antioxidant potential. A complete characterization functional properties films, such as their structural, colour, thermal, mechanical, hydration and water vapour transport, was carried out to evaluate influence addition compounds....
The production of indigo, primarily used by the denim industry, increases year year, and is mainly synthetic origin. textile on which its depends, responsible for 10% greenhouse gases 20% water pollution. However, source this pigment/colorant, based petrochemistry, remains a key issue today. Extracting indigo from plants becoming popular answer requires an understanding evaluation entire process, raw material to pigment recovery. In study, indigotin precursor, indoxyl, derived hydrolysis...
