Title: Effect of a New Attachment in Rapier Loom on Properties of Textiles Authors: Shen G T, Pavithra; Kumar M, Ramesh; Ahmed Qureshi, Sajid; Das, Subrata Abstract: Design and development of an innovative automated device focus on eliminating the auxiliary selvedge in shuttleless rapier looms. This auxiliary selvedge continuously contributes to increased material waste, additional labor and time for removal. So, the proposed device integrates cutting-edge automation technologies with existing loom mechanisms to address these challenges. The auxiliary selvedge is by grasping the protruding weft ends after each pick insertion in the weaving process, with consequent cutting and suctioning the projecting ends and so the device presents a sustainable solution for the textile industry by optimizing material utilization and by reducing the production costs. The scaling down in material remnants was quantified, and the quality of fabric is analyzed by testing the yarn density, areal density, tensile strength, tearing strength, bursting strength, air permeability, dimensional stability and crimp percentage for the fabric produced before and after installation of the attachment. A new attachment to the loom significantly reduces yarn wastage and cost, achieving a 62.5% reduction in both, without altering the loom's constructional parameters in the process of weaving and the produced fabric quality. The statistical significance of the fabric properties produced with and without the attachment was evaluated using a t-test. No significant differences were found in yarn density, areal density, tearing strength, and dimensional stability of the fabrics produced with and without the attachment. However, there were slight but statistically significant differences observed in crimp percentage, tensile strength, bursting strength, and air permeability of the fabrics produced with and without the attachment Page(s): 1041-1050

Title: Formulation of Corchorus olitorius Leaves and Jowar-based Ready-to-Eat Snack Authors: Soujanya, Kanneboina; Anila Kumari, B.; Jyothsna, E Abstract: India has a great heritage of traditional snack foods. Murukku is a traditional snack of Telangana state, India, which has a distinct culture and food habits. A ready-to-eat, nutritious snack was developed by blending sorghum flour, Corchorus olitorius leaves, and other ingredients in optimal proportions. The developed product's sensory evaluation, nutrient, and phytonutrient composition were analysed. This nutritional powerhouse and sensory delight snack was crafted with a perfect blend of taste and texture. The unique combination of ingredients, carefully balanced flavours, and textures makes it a treat for the senses. Based on the sensory data, 10% Corchorus olitorius leaves incorporated murukku (JMCO- Jowar murukku with 10% incorporation of Corchorus olitorius) was selected for further study and compared with the control (JMC). The addition of Corchorus olitorius in murukku significantly (p < 0.01) enhanced the ash content (4.26%), crude protein level (16.87%), and crude fibre (3.84%), while reducing the carbohydrate content (45.56%) and energy content (480.6 kcal/100g). Adding leaf powder significantly (p < 0.01) enhanced the vitamin and mineral content of murukku, providing a wealth of nutritional benefits. Total phenol, flavonoid, tannin, and antioxidant activity of murukku (JMCO) were 122.14 mg GAE/100g, 60.3 mg RE/100g, 20.97 mg TAE/100g, and 5.57% respectively. Corchorus olitorius leaves and jowar-based ready-to-eat murukku have good sensory, nutritional, and phytonutrient properties. Page(s): 1051-1058

Antimicrobial Activities of Lipoxazolidinone A Purified from Lactobacillus apis YMP3 against Various Infant Diarrheal Pathogens and its Cytotoxicity against Normal Mammalian Cells

Title: Antimicrobial Activities of Lipoxazolidinone A Purified from Lactobacillus apis YMP3 against Various Infant Diarrheal Pathogens and its Cytotoxicity against Normal Mammalian Cells Authors: Satish Kumar, Dayanidhi; Venkatachalam, Palanisamy Abstract: Infant diarrheal infections continue as one of the critical challenges of global health issues, demanding the development of safe therapeutic solutions; hence, this study was performed. This study explores the antimicrobial potential of lipoxazolidinone A against various infant diarrheal infectious pathogens and its cytotoxicity against mammalian cells. As reported earlier in our studies, this compound was produced and purified from a probiotic Lactobacillus apis YMP3. The antimicrobial study was performed in this study against a panel of 12 clinical bacterial pathogens causing infant diarrheal infections, collected from the Thanjavur Government Medical College, Thanjavur, Tamil Nadu, India. The purified lipoxazolidinone A showed appreciable antimicrobial activities against seven pathogens viz., Vibrio cholerae, Proteus mirabilis, Salmonella typhi, Vibrio vulnificus, Bacillus cereus, Escherichia coli, and Salmonella paratyphi, at the minimum inhibitory concentration of 100, 125, 150, 150, 150, 175, and 200 μg/ml, respectively, and the remaining five pathogens, viz., Pseudomonas aeruginosa, Staphylococcus aureus, Klebsiella oxytoca, Shigella dysenteriae, and Shigella boydii, revealed partial growth inhibition of 73, 56, 37, 27 and 21% at the highest tested concentration (200 μg/ml), respectively. The cytotoxicity studies of lipoxazolidinone A using two normal mammalian cell line cultures, viz., primary mouse embryonic fibroblast cells (NIH/3T3) and Madin-Darby Canine kidney cells (MDCK), evidenced negligible toxicity till 400 μg/ml. These findings reveal that lipoxazolidinone A is a promising antimicrobial candidate, proving its appreciable inhibitions against pathogenic bacteria and nontoxicity towards mammalian cells. The mammalian cell-safe antimicrobial activities of lipoxazolidinone A suggest futuristic research for the potential drug development in treating many infant gastrointestinal infections Page(s): 1059-1068

Title: Isolation of Multi Stress Tolerant Yeast for Ethanol Production at Elevated Temperature Authors: Pal, Upma; Saifi, Rizwan; Pal, Sumit; Vij, Shilpa Abstract: In recent decades, bioethanol and biofuels have emerged as alternatives to fossil fuels globally. Utilizing dairy waste (whey) as substrate is lucrative option for utilizing it and producing ethanol. Therefore, in deliberating the cost-effectiveness of ethanol fermentation there is a requirement of a microorganism strain that can convert substrate (lactose) into ethanol at higher temperatures. The study aims to isolate multi-stress tolerant lactose fermenting yeast strain for economical production of ethanol. Out of 215 samples of lactose fermenting yeast 9 strains were selected for ethanol production. Taxonomical identification and multi-stress tolerance (thermal, sugar, ethanol) of the 9 strains were conducted. After optimizing ethanol production at different temperatures (37℃, 40℃, 42℃, 45℃), significant ethanol production (8% v/v) could be observed at 37℃ in 40 h from 15% w/v lactose (YPL medium) while at 40℃ and 42℃ the productivity of ethanol slightly decreased, i.e., 7.5% v/v after 30 h with 0.5% residual lactose and at 45℃, only 3.5% v/v ethanol has been produced with approximately 7.5% w/v residual lactose. Thus, the isolated Kluyveromyces sp. 6C17 strain showed notable stress tolerance, making it promising for economical bioethanol production using lactose containing substrates at high temperature Page(s): 1069-1075
