A full‐length cDNA and the corresponding At‐P5S gene encoding first enzyme of proline biosynthetic pathway, Δ 1 ‐pyrroline‐5‐carboxylate (P5C) synthetase, were isolated in Arabidopsis thaliana . The encodes a protein 717 amino acids showing high identity with P5C synthetase Vigna aconitifolia Strong homology is also found at N‐terminus to bacterial yeast γ‐glutamyl kinase C‐terminus phosphate reductase. Putative ATP‐ NAD(P)H‐binding sites are suggested protein. transcribed region 4.8 kb long...
Aspergillus spp. infection of grape may lead to ochratoxin A (OTA) contamination in processed beverages such as wine and juice. The aim the current study was evaluate biocontrol potential two non-fermenting (Cyberlindnera jadinii 273 Candida friedrichii 778) low-fermenting (Candida intermedia 235 Lachancea thermotolerans 751) yeast strains against pathogenic fungus OTA-producer carbonarius, their ability remove OTA from Two strains, 751, showed a significant inhibit A. carbonarius both on...
Detection and identification of new antagonistic activities towards Bacillus cereus relatives.Twenty thuringiensis strains were screened for their capacity to express bacteriocin-like agents. Strain BMG1.7, isolated from soil, showed an activity called thuricin 7. Thuricin 7 was active against several species the genus Bacillus, including three four known B. thuringiensis/B. bacteriocin producers, as well Streptococcus pyogenes Listeria monocytogenes strains. Antimicrobial lost after...
We are interested in this paper recovering lacking data on some part of a domain boundary, from the knowledge Cauchy other part. It is first proved that desired solution unique fixed point appropriate operator, which naturally gives rise to an iterative process be convergent. Discretization provides additional regularization: algorithm reads as least square fitting given data, with regularization term effect fades iterations go on. Displayed numerical results highlight its accuracy, well robustness.
The use of yeast-derived volatile organic compounds (VOCs) represents a promising strategy for the biological control various plant pathogens, including mycotoxin-producing fungi. Previous studies demonstrated efficacy low-fermenting yeast Candida intermedia isolate 253 in reducing growth, sporulation, and ochratoxin A biosynthesis by Aspergillus carbonarius MPVA566. This study aimed to investigate whether inhibitory effect volatilome is solely attributable 2-phenylethanol, its major...
Climate change is predicted to have a significant impact on the geographic distribution of various flora, fauna, and insect species by expanding, contracting, or shifting their suitable climate environment. The plant pathogenic fungus Fusarium known for causing crop diseases like blight, root stem rots, wilts, making it most mycotoxigenic genus in weeds food across climatic zones worldwide. In this study, we hypothesize that caused spp. will increase all four corners world 2050 2070 response...
We consider the problem of determining Robin coefficient some specimen material, by performing measurements on part boundary. An identifiability result is proved for coefficients which are continuous functions with negative lower bound. Both local and monotone global Lipschitz stability results established. Finally, a cost function turning inverse into an optimization one proposed numerical purposes. This function, may be viewed as energetic least-squares one, has easy-to-compute...
Purification and characterization of a new bacteriocin, Bacthuricin F4 Bacillus thuringiensis.A newly isolated B. thuringiensis subsp. kurstaki strain BUPM4, was shown to produce novel bacteriocin named F4. The highest activity found in the growth medium evidenced late exponential phase. could be purified by two-step procedure: ammonium sulphate precipitation protein from culture supernatant followed reverse phase chromatography. Upon purification, specific increased 100-fold. This...
The moulds' filling process may generate flaws consisting of small gas bubbles trapped inside the material, which weaken solidity casted piece. We consider here inverse problem determining these size flaws' locations from velocities boundary measurements. fluid flow is described by a simplified model based on Stokes system. A numerical algorithm topological sensitivity analysis applied to an energy-like misfit functional worked out that end.
Dolomite (MgCa(CO3)2) is an important petroleum reservoir rock mineral common in ancient sedimentary rocks which infrequently found modern environments. The mechanism of dolomite formation remains poorly understood, although recent research has focused on the contribution microbial processes. Sabkha Arabic term for saline mudflats occurring regions characterized by extreme environmental conditions (high temperature, salinity, light intensity, and aridity), where diverse halophilic...
