“…The maximum inhibition zone against P. aeruginosa was observed in case of antibiotic followed by peel extract with mean inhibition zone of 19.00 mm and 13.50mm, respectively and the minimum inhibition was observed in case of pomace extract with mean inhibition zone of 9.05 mm. The results were closely related to the findings of Fratianni et al [31]. Who observed 6 mm to 13mm inhibitory zone of apple extracts against E. coli.…”

The present study was designed to evaluate the antibacterial activity of aqueous extracts of Malus domestica (peel and pomace) against food-borne pathogens (Escherichia coli, Pseudomonas aeruginosa, Staphylococcus aureus and Enterococcus feacalis). Extraction conditions (temperature and time) were optimized to obtain maximum yield by using response surface methodology. Antibacterial potentials of the extracts were examined through disc inhibition zone technique and the results were compared with commercial antibiotic. Results Indicated that maximum antibacterial activity was shown by peel extract against Staphylococcus aureus with average zone of inhibition 19.25±0.89 mm while pomace 12.75±0.71 mm. Maximum recovery for water soluble compounds from peel was obtained at 70ºC followed by 90ºC and 50ºC, which was 16.33, 14.67 and 12.67%, respectively. The extraction yield was also increased but after 30 minutes. The antibacterial activities of peel extract were comparable with commercial antibiotic (20.13±0.83 mm). Escherichia coli were appeared to be the most resistant with inhibition induced by the extracts of peel 15.00±1.07 mm and pomace11.50±0.53mm.

“…The increasing number of research studies have found that apples can possess some antimicrobial activity. Conventionally produced apples inhibited Bacillus cereus , while the organic peel demonstrated antimicrobial activity against Escherichia coli 0157:07 [ 47 ]. It was also reported that the presence of phloretin and its glycosylated derivatives in apples are able to inhibit growth of Gram-positive bacteria, and are active against some strains of the Gram-negative bacteria [ 48 ].…”

Bioconversion of Milk Permeate with Selected Lactic Acid Bacteria Strains and Apple By-Products into Beverages with Antimicrobial Properties and Enriched with Galactooligosaccharides

et al. 2020

The present research study aims to prepare prototypes of beverages from milk permeate (MP) using fermentation with 10 different strains of lactic acid bacteria (LAB) showing antimicrobial properties (L. uvarum LUHS245, L. casei LUHS210, L. curvatus LUHS51, L. plantarum LUHS135, P. acidilactici LUHS29, L. plantarum LUHS122, L. coryniformins LUHS71, L. paracasei LUHS244, P. pentosaceus LUHS183, L. faraginis LUHS206) and MP with (AppMP) or without (MP) the addition of 8% (w/w) apple by-products (App). Two groups of prototypes of beverages were prepared: fermented MP and fermented MP with App (AppMP). Acidity parameters, LAB viable counts, lactose and galactooligosaccharides (GOSs) content, antimicrobial properties against 15 pathogenic and opportunistic bacterial strains, overall acceptability and emotions induced of the final fermented beverages for consumers were evaluated. Results showed that all LAB grew well in MP and LAB strain exhibited a significant (p ≤ 0.05) influence on galactobiose and galactotriose synthesis in the fermentable MP substrate. The highest total content of GOS (26.80 mg/100 mL) was found in MPLUHS29 fermented beverage. In addition, MPLUHS245, MPLUHS210 and AppMPLUHS71 fermented beverages showed high antimicrobial activity, inhibiting 13 out of 15 tested microbial pathogens. The overall acceptability of AppMP fermented beverages was 26.8% higher when compared with fermented beverages without App (MP), and the most intensive “happy” emotion was induced by MPLUHS71, MPLUHS24, MPLUHS183 and MPLUHS206 samples. Finally, very promising results were also attained by the bioconversion of MP with selected LAB and App addition into the prototypes of antimicrobial beverages enriched with GOS.

“…In another study by Florida Fratianni et al .,[ 10 ] antimicrobial effect of two varieties of apples: organically produced and conventionally produced apples were tested against useful lactobacillus species and pathogenic microorganisms, i.e., Bacillus cereus , which is responsible for several cases of foodborne illness and the enterohemorrhagic E. coli , that causes serious cases of food poisoning. None of the apple extracts assayed gave positive results against the 6 strains of lactic acid bacteria.…”

Evaluation of antibacterial activity of three selected fruit juices on clinical endodontic bacterial strains

et al. 2017

View full text Add to dashboard Cite

Introduction:The increasing problem of antibiotic drug resistance by pathogenic microorganisms in the past few decades has recently led to the continuous exploration of natural plant products for new antibiotic agents. Many consumable food materials have good as well as their bad effects, good effect includes their antibacterial effects on different microorganisms present in the oral cavity. Recently, natural products have been evaluated as source of antimicrobial agent with efficacies against a variety of microorganisms.Methodology:The present study describes the antibacterial activity of three selected fruit juices (Apple, Pomegranate and Grape) on endodontic bacterial strains. Antimicrobial activity of fruit juices were tested by wel l diffusion assay by an inhibition zone surrounding the well. The aim of the study was to evaluate the antibacterial activity of three fruit juises on different endodontic strains.Result:Agar well diffusion method was adopted for determining antibacterial potency. Antibacterial activity present on the plates was indicated by an inhibition zone surrounding the well containing the fruit juice. The zone of inhibition was measured by measuring scale in millimeter. Comparision between antibacterial efficacy of all three fruit juices against Enterococcus feacalis and Streptococcus mutans was observed with significant value of P ≤ 0.05.Conclusion:The results obtained in this study clearly demonstrated a significant antimicrobial effect of apple fruit juice against Enterococcus fecalis and Streptococcus mutans. However, preclinical and clinical trials are needed to evaluate biocompatibility & safety before apple can conclusively be recommended in endodontic therapy, but in vitro observation of apple effectiveness appears promising.
