Nisin, a bacteriocin produced by some strains of Lactococcus lactis, acts against foodborne pathogen Listeria monocytogenes. A single exposure of cells to nisin can generate nisin-resistant (Nisr) mutants, which may compromise the use of nisin in the food industry. The objective of this research was to compare the heat resistance of Nisr and wild type (WT) Listeria monocytogenes. The synergisti...
بمنظور ارزیابی کشت مخلوط ذرت (zea mays l.) و لوبیا (phaseolus vulgaris l.) آزمایشی در قالب طرح بلوکهای کامل تصادفی با 11 تیمار و سه تکرار اجرا گردید. تیمارهای آزمایش شامل کشت مخلوط تراکم معمول ذرت(c) با تراکم معمول لوبیا(b) باضافه 10%،20 % و30% {b(c+30%c),b(c+20%c),b(c+10%c)} ، کشت مخلوط تراکم معمول لوبیا(b) با تراکم معمول ذرت(c) باضافه 10%، 20% و 30% {b(c+30%), b(c+20%),b(c+10%)} کشت مخلوط ترا...
The effect of environmental conditions on the fracture behaviour two types adhesively bonded joints (wet-aged and non-aged) is experimentally studied under mode II loading. End Loaded Split tests were performed at various temperatures (−55 °C, room temperature (RT) 80 °C) non-aged aged specimens. specimens stored in a laboratory controlled RT (23 °C/55 RH) while wet-aged exposed to accelerated ...
Anthrax outbreaks in livestock have social, economic and health implications, altering farmer's livelihoods, impacting trade and posing a zoonotic risk. Our study investigated the survival of Bacillus thuringiensis and B. anthracis spores sporulated at 15, 20, or 37°C, over 33 days of composting. Spores (∼7.5 log10 CFU g(-1)) were mixed with manure and composted in laboratory scale composters. ...
Methyl oleate, an example of a FAME (fatty acid methyl ester), was produced by oleic (OA) photoesterification with TiO2 and UVA light. Different parameters were evaluated optimised: catalyst pretreatment, temperature (25–65 °C), loading (1–30 % w/wOA) : alcohol molar ratio (1 3–1 55). Response surface quadratic methodology obtained central composite rotational design (RSM-CCRD) used to evaluate...
