Abstract. Deshmukh AS, Siddiqui MM, Pathan UK, Dhuldhaj UP. 2020. Microbial study of organisms isolated from nutritional fruit juices surrounded by local fruit market in Nanded, Maharashtra, India. Biodiversitas 21: 4240-4246. Growing populations depend on the various food products for their nutritional values, but the hidden hunger for nutrients and vitamins are fulfilled by the fruits and their juices. Fruit juices are one of the most dependable food products, available in the Indian markets. But, standard and quality of juices always matters, hence most suggested one are freshly prepared juices as processed and packed one are mostly contains artificial flavors and food additives in the form of preservatives. Even these freshly prepared juices by local staler are also not free from contaminations. Hence, in this study we focus on the quality of fruit juices sold by the local seller. For this purpose, we collected 5 samples of fruit juices from the premises of Swami Ramanand Teerth Marathwada University, Nanded. The fruit juices are on orange, chiku, banana, apple and grapes. These samples were maintained in the basal media nutrient broth and uniculture of bacteria were isolated and maintained in the slant agar for further experiments. Total microbial load was calculated from collected and it was found that these juice samples contain significant bacterial load (2.5 x 106cfu/mL) that can cause diseases. In further investigations and identifications through the biochemical tests, we found that these juices contaminated with coliforms like E. coli and Klebsiella, along with this we also detected the presence of Listeria spp and Staphylococcus in juices samples.

This study demonstrates the antimicrobial activity of three spices, Piper guineense (Uziza), Xylopia aethiopica (Uda), Tetrapleura tetraptera (oshorisho) and their potential use as food biopreservatives. Essential oils of the spices seed were obtained and used in the agar-diffusion and tube dilution assays to determine their minimum inhibition (MIC) and bactericidal concentrations (MBC) against a common fruit juice spoilage organism (Bacillus cereus). MIC values of 50mg/ ml (Oshorisho) and 25mg/ml (Uziza and Uda) were obtained. Similarly, all spice extracts were bactericidal at a concentration of 100mg/ml. The spice extracts were utilized in the fortification of fresh fruit juice. Fortification of orange, pineapple and watermelon juices with extracts of the spices caused a reduction in the bacterial and fungi load of the juices over a period of 7 days in comparison to unpreserved controls. Orange juice preserved with uda had a fungal load of 1.9 x106 and bacterial load of 8.0 x106 compared to control with loads of 2.3 x107 and 1.1 x107 , respectively. Watermelon juice preserved with oshorisho had a fungal load of 1.2 x106 and bacterial load of 1.1 x107 compared to control with loads of 2.1 x107 and 8.8 x107 , respectively while pineapple juice preserved with uziza had a fungal load of 1.2 x107 and bacterial load of 1.6 x107 compared to control with loads of 2.7 x107 and 2.5 x108 , respectively. These results show that the spice extracts have potential for use as food preservatives for extending the shelf life of freshly prepared fruit juices. This is important as the demand for fresh foods free from chemical preservatives but microbiologically safe is on the increase.

<div>The failure of frontline antibiotics in the clinic is one of the most serious threats to human health and requires a multitude of novel therapeutics and innovative treatment approaches to curtail the growing crisis. In addition to traditional resistance mechanisms resulting in the lack of efficacy of many antibiotics, most chronic and recurring infections are further made tolerant to antibiotic action by the presence of biofilms. Herein, we report an expanded set of 5-benzylidene-4-oxazolidinones that are able to inhibit the formation of Staphylococcus aureus biofilms, disperse preformed biofilms and in combination with common antibiotics are able to significantly reduce the bacterial load in a robust collagen-matrix model of biofilm infection.</div>
