The optimum decolourisation (72.6%) of melanoidin was achieved at pH 7.5 and temperature 37 °C within 4-6 days fermentation. The toxicity evaluation of distillery effluent with mung bean (Vigna radiata) revealed that the raw effluent is highly toxic as compared to treated effluent. This indicated that the effluent after bacterial treatment is ecofriendly

Isolation, characterization and optimization of bacterial isolate SARR1 for biodegradation of pretreated low density polyethylene

Accumulation of low-density polyethylene (LDPE) has caused a threat to the environment because of its stable and inert nature as it cannot be degraded easily by microorganisms. Its lightweight, low cost, strength, durability, and its various other applications, have led to the wide usage of the polymer, which is exerting a negative effect on both marine and land biota. The development of an eco-friendly or a promising strategy is needed to reduce LDPE waste from both land and water. In the present study, observations have been made to isolate highly efficient LDPE degrading bacteria. The response surface methodology (RSM) was used to predict the best optimization of media for the degradation of LDPE by isolate SARR1. The isolate SARR1 was selected through primary screening by weight loss method and secondary screening using CO2 evolution test, TTC and MATH Test. The isolate SARR1 showed 6.30 ± 0.25 g/L CO2 evolution. The microbial adhesion hydrophobicity (MATH) was observed during log phase (100 to 56.89 ± 0.97 %) and stationary phase (100 to 82.92 ± 1.24 %). An isolate SARR1 converted the TTC into red coloured insoluble triphenyl formazan (TPF) after incubation of 7 days. The isolated bacteria SARR1 showed 38.3 ± 1.27 % biodegradation efficiency in the pretreated LDPE strips at 37 °C and pH 7.0 under optimized conditions within 30 days of incubation. This bioremediation and biodegradation approach is eco-friendly and safe for the environment. The results of treatment with isolate SARR1 had a potential hope to degrade LDPE at higher rate than natural degradation. 

CROSS-SECTIONAL STUDY OF ASSOCIATION BETWEEN GLYCEMIC CONTROL AND QUALITY OF LIFE AMONG DIABETIC PATIENTS

Objective: The present study aimed to evaluate the association between glycemic control and quality of life (QoL) in people with type 2 diabetesmellitus (T2DM) and identify that factors that influence glycemic control and QoL.Methods: This cross-sectional study was conducted at the general hospital in Depok City from October to December 2017. Respondents wereoutpatients diagnosed with T2DM, receiving routine care at the hospital. Glycemic control was assessed using glycated hemoglobin (HbA1c) levels,while QoL was measured using an Indonesian version of the validated 5-level EuroQol 5-Dimensional.Results: Among 108 participants, HbA1c levels were influenced by age, DM disease duration, DM treatment adherence, glycemic control, diet, andphysical activity suitable for patients with DM. The mean QoL value was 0.74±0.23 and the visual analog scale (VAS) score was 65.49±15.96. The QoLvalues of patients with DM were influenced by HbA1c levels, duration of DM, and physical activity, while the VAS score was significantly affected byHbA1c levels and duration of DM.Conclusion: The present study showed that the QoL of T2DM patients was significantly influenced by glycemic control and other factors

Influence of blend ratio on physical properties of oak tasar silk and acrylic blended spun yarn

In this study an attempt was made to utilize the oak tasar silk spinning waste through blending it with acrylic fibre and prepared yarn in mechanised spinning system.  The oak tasar silk and acrylic blended yarn were prepared on ring spinning machine with five different blend ratios viz. 100:0, 60:40, 50:50, 40:60 and 0:100. The prepared yarns were of medium to fine yarn count. Yarn Physical properties of yarns, unevenness and imperfections were studied and statistically analysed. Results revealed that the 100% acrylic and 50:50 tasar acrylic blended yarns had better properties as compared to 60:40 and 40:60. The addition of acrylic fibre content improved the physical properties, unevenness and imperfection of the blended yarns

Sustainable traditional dyeing of wool by Bhotia tribe in Himalayan region: A case study

Bhotia tribe is one of the community residing in the high Himalayan region of Uttarakhand state that shares the border with Tibet. The tribe is divided into five sub-groups viz., the Jadhs ,  Marchas, Tolchas ,  Shaukas and Rung. The present study was conducted in the five villages namely Lata and Chinka from Chamoli, Darkot and Baluwakot from Pithoragarh and Dunda from Uttarkashi of Uttarakhand for exploring the information from different sub-groups of Bhotia tribe about plants used by them for extracting dyes and used for traditional textile coloration in past and during present time. The rich flora of Himalayan region in Uttarakhand has been abode to varieties of plant species. The wild plant species were used by the Bhotia tribals for dyeing their woolen products. These plant dyes were obtained from jangli palak (Rumex nepalensis), bagmaru (Eupatorium), kilmora (Berberis asiatica), akhrot (Juglans regia), dholu (Rheum aystrale), tea leaves, tantri (Rheum moorcroftianum), kaphal (Myrica esculenta), darim (Punica grantum), burans (Rhodendron araborium) and harda (Terminlia chebula). Today only Shauka and Jadh tribals are using natural dyes for dyeing woolen yarn. Reasons for the reduction in usage of natural dyes among Bhotia tribals were the extinction of plant species, change in land use, natural disasters, government restriction on plucking certain plant species, the availability of synthetic dyes and colored yarns at low cost in the market. The identification of factors that led to the non-practice of sustainable dying practice among tribals for woolen craft will help in planning and conducting interventions through public, private and government organizations

Extraction of natural dye from the leaves of Wild Himalayan pear (Pyruspashia) and optimization of the dyeing parameters using Box-Behnken Design (RSM)

Today universe is inclined towards eco-friendly and sustainable products. Its interest is shifting from synthetic products to natural once. The present study involves the optimization of extraction pH of natural dye and optimization of dyeing parameters for dyeing of silk fabric using response surface methodology (RSM). The extraction of dye from the leaves of Pyrus pashia (Wild Himalayan pear) was carried out in acidic, neutral and alkaline pH. The neutral pH exhibited the highest colour strength than alkaline and acidic pH. Box-Behnken Design (RSM) was used for optimization of dyeing variables. The effect of independent variables i.e. dye material concentration, dyeing time and temperature were assessed on dependent variable i.e colour strength of the dyed silk fabric sample. The optimized dyeing variables obtained for application of P. pashia leaf dye on silk fabric were 5% (w/v) dye material concentration, 70°C dyeing temperature and 45 minutes dyeing time. It not only creates a source for a natural dye but can also lead to creating employment amongst the rural people. P. pashia has a potential to colour silk fabric and can be used to dye other natural fibres such as cotton and wool which can be a step towards sustainable development. dyeing with its leaf extract can be helpful in promoting eco-friendly processing of textiles
