“…2.8 | Determination of antioxidant activities by ABTS scavenging ability ABTS scavenging ability was determined according to the method of Chang, Wang, Yang, Chena, and Song (2011). An aqueous solution of ABTS (7 mM) was oxidized with potassium persulfate (2.45 mM) for 16 hr in the dark at room temperature.…”

Germinated green gram seeds are widely consumed in the world. During germination, significant volume of exudate is wasted. Total polyphenol, flavonoid and anthocyanin contents in exudate were 80.8 mg GAE/g, 52.42 mg CAE/g and 15.23 µg/g (dw), respectively. In exudate, sinapic acid content was the highest followed by ferulic and gallic acids. Similarly, polyphenol and flavonoid contents in germinated seeds increased, while in husk, it decreased significantly with the germination period, however, anthocyanin content decreased significantly in both. During germination, contents of tannic and gallic acids decreased, while contents of ferulic and sinapic acids increased in both seed and husk. Exudate exhibited potential antioxidant and antibacterial activities. First day germinated seed and husk had the highest antioxidant and antibacterial potential. Thus, exudate and germinated seed extracts can be used as nutraceuticals and used in functional foods. This is the first report on antioxidant and antibacterial properties of green gram exudate. Practical applications Germinated seeds are rich in nutrients and nutraceuitcals. Food industry produces significant amount of germinated green gram and these germinated seeds are consumed as raw as well as after mild processing. After germination, large quantities of liquid as well as husk are obtained. As germinating seeds produce antimicrobial compounds to protect the seedlings, during germination these compounds may leach into exudate. In the present study, we found that green gram exudate and the germinating seed husks possess stronger antioxidant and antibacterial activity against food borne bacteria compared to raw seed. The results suggest that the exudate can be a good source of natural preservatives in food products and it may be an alternative to the use of chemical additives in the food industry.

“…Many treatment options have been investigated in the past few years for treating hard-to-heal wounds; however, none of them seem to be optimal for an effective management [32, 58]. Honey as a wound dressing provides a moist environment but also antibacterial and anti-oxidative action from the presence of high osmosis, hydrogen peroxide, and other substances [15, 26, 30]. It has also been reported to reduce swelling and inflammation and can decrease the healing time by stimulating angiogenesis, granulation, and epithelialization [2, 15].…”

Fighting Off Wound Pathogens in Horses with Honeybee Lactic Acid Bacteria

In the global perspective of antibiotic resistance, it is urgent to find potent topical antibiotics for the use in human and animal infection. Healing of equine wounds, particularly in the limbs, is difficult due to hydrostatic factors and exposure to environmental contaminants, which can lead to heavy bio-burden/biofilm formation and sometimes to infection. Therefore, antibiotics are often prescribed. Recent studies have shown that honeybee-specific lactic acid bacteria (LAB), involved in honey production, and inhibit human wound pathogens. The aim of this pilot study was to investigate the effects on the healing of hard-to-heal equine wounds after treatment with these LAB symbionts viable in a heather honey formulation. For this, we included ten horses with wound duration of >1 year, investigated the wound microbiota, and treated wounds with the novel honeybee LAB formulation. We identified the microbiota using MALDI-TOF mass spectrometry and DNA sequencing. In addition, the antimicrobial properties of the honeybee LAB formulation were tested against all wound isolates in vitro. Our results indicate a diverse wound microbiota including fifty-three bacterial species that showed 90 % colonization by at least one species of Staphylococcus. Treatment with the formulation promoted wound healing in all cases already after the first application and the wounds were either completely healed (n = 3) in less than 20 days or healing was in progress. Furthermore, the honeybee LAB formulation inhibited all pathogens when tested in vitro. Consequently, this new treatment option presents as a powerful candidate for the topical treatment of hard-to-heal wounds in horses.

The beneficial effects of honey on human health have long been recognized. Today, many of those positive effects have been studied to elucidate its mode of action. This review briefly summarizes the best studied features of honey, highlighting it as an appealing alternative medicine. In these reports, the health benefits of honey range from antioxidant, immunomodulatory, and anti-inflammatory activity to anticancer action, metabolic and cardiovascular benefits, prebiotic properties, human pathogen control, and antiviral activity. These studies also support that the honey’s biological activity is mainly dependent on its floral or geographic origin. In addition, some promising synergies between honey and antibiotics have been found, as well as some antiviral properties that require further investigation. Altogether, these studies show that honey is effectively a nutraceutical foodstuff.
