Different volume of silver nanoparticle solution (15, 10, and 5 ml) were used in producing the edible films. the films were evaluated for their inhibitory effectiveness against some types of bacteria that cause food spoilage. The results showed that the gelatin films containing 10 ml of silver nanoparticle solution gave effective activity against Bacteria for all strains tested. The results also showed an improvement in the mechanical properties of the coating supported with silver nanoparticles, as the thickness increased to 0.9 mm compared to the regular control gelatin film of 0.5 mm. Therefore, the tensile strength and elongation rate of the nano-silver treated films increased compared to the control regular coatings. The results also showed that the solubility of the regular gelatin film was 45.2% which significantly diffed from the solubility of the Nano-silver gelatin treated film, which recorded approximately half the solubility (23.3%).

Abstract. A total of twelve bacterial isolates from different samples of yoghurt and milk purchased from local markets in Diwaniyah Governorate. The preliminary screening was carried out all bacterial isolates by gram staining. The six isolates were selected based on the intensity of colour variation in the fermentation medium and were identified according to phenotypic, microscopic, and biochemical examinations, which included twelve isolates of Lactobacillus spp. Vitek II Compact instrument was used with all isolates to confirm the initial identification. The secondary screening was performed for isolates of Lactobacillus spp.species. Given the amount of the produced lactic acid, the L.casei strain 1859 had the highest lactic acid production, which was 64.32 g/L. The 16S rRNA test allowed the identification of this isolate. The results showed that the best conditions for acid production were 62.76 mg/L and the L.casei strain 9836 grown on the alternative medium containing 50 % whey, 7% molasses, and pH 6.9, incubated on an orbital shaker at 38°C for 24 hours, and agitated at 250 rpm. FTIR techniques were used to identify the nucleus of the hydrogen atom (proton) 1H and the carbon atoms 13C in the presence of standard lactic acid for comparison. The results revealed the peaks and bands of the produced acid were some similar to that of the standard acid.
