Besides being an essential source of nutrients, the bioactive components of some fruits also help in enhancing the physiological functions by expressing its therapeutic action, acting as radical scavenger, improving digestion and healing. Here, seven edible fruits juices of Punica granatum, Citrus reticulata, Anana scomosus, Ficus carica, Vitis vinifera, Vitis amurensis and Carica papaya were utilized against biofilm forming Gram negative bacteria, Pseudomonas aeruginosa to evaluate its effect on Quorum sensing. On proving its antibacterial activity and anti-swarming motility in our earlier report, this work is extended to determine the biofilm inhibitory action of these fruit juices due to the impact on AHL (Acyl Homoserine lactone), the signaling molecule responsible for developing cell-cell communication and also on AHL mediated metabolites production. The fruit juices were evaluated for their Antioxidant activity on subjecting to TLC bioautography, DPPH and FRAP assay. AHL, Pyocyanin and Rhamnolipid were extracted from fruit juices treated Pseudomonas aeruginosa and the influence of fruit juice was identified by FT-IR and LC-MS analysis. However, AHL production was not stopped by fruit juice molecules but showed least production level in Punica granatum treated P.aeruginosa. Whereas the production of pyocyanin pigment was disturbed in Punica granatum, Citrus reticulata, Vitis amurensis and Vitis vinifera treated culture. The production of a biosurfactant called Rhamnolipid (Rha 10) was a failure in Citrus reticulata, Vitis amurensis, Vitis vinifera and Ficus carica treated P.aeruginosa. Thus the organism was restrained by the fruit juice molecules from expressing its virulence factors in spite of having no impact on AHL synthesis.

“…Introduction of nanoparticles into tanning agents enhances the physical and mechanical properties of leather [60]. In order to this, silver nanoparticles due to its properties against bio-activities they can even impart some functional properties such as anti-microbial, UV-resistance and fungal resistance of leather [60][61][62][63]. Raji et al (2019) used various tannins mediated silver nanoparticles for tanning process and able to produce a stable leather [64].…”

There are several processes involved in leather making, one of the process is tanning. In tanning process, higher concentration of chromium is commonly used. Whereas chromium is regarded as one of the toxic heavy metal. The disposal of these chromium effluent into water bodies is known to cause various ill effects. To replace that, vegetable tanning can be practiced, where the method is easy as well as ecofriendly. In this review, we have dealt about various procedures in leather processing especially chrome tanning and health hazards caused by chromium. Also added a note on vegetable tanning using tannins to replace the chrome tanning for making better environment.

“…TLC Bioautography were performed for separation of individual plant component in the extract using silica plates (Merck, F245) 34 . Each plant extract was loaded onto silica plates and the chloroform extracts were run having chloroform: benzene: acetonitrile: ethanol (3:2:0.5:0.5) and water extracts were run with the mobile phase of water: butyl alcohol: acetonitrile: ethanol: ethyl acetate (1:1:1:0.5:0.5) respectively.…”

Five plant species namely, Phyllanthus acidus, Piper aduncum, Pandanus amaryllifolius, Macaranga peltata and Acacia mangium were analysed for their effective in-vitro bioactivity. The chloroform and aqueous extracted of the selected plants were subjected to TLC bioautography for antioxidant activity later all the extracted were subjected for DPPH assay where the chloroform extracts were found to express maximum antioxidant property. Amongst all the plants, Macaranga peltata accounted to 95% DPPH scavenging activity. The antimicrobial studies of the plant extracts were performed via agar well diffusion method, MIC determination, Biofilm inhibition assay in microtitre plate against clinical isolates like Staphylococcus aureus (MRSA) and Pseudomonas aeruginosa. It was found that Piper aduncum (chloroform and aqueous extract) and Macaranga peltata (only aqueous) expressed antibacterial activity, of which only chloroform extract of Piper aduncum could show negative influence against the biofilm development of P.aeruginosa.
