“…Heavy metal tolerance assay Contamination occurring from metals like mercury (Hg), arsenic (As), and cadmium (Cd) etc. poses a serious toxic threat to all living organisms as it can cause cancer in humans when present in small quantities (Acharyya et al, 2021). These traumatic and stressful surroundings often encourage microbial populations to adapt and gain tolerance toward the metals.…”

Leguminous shade trees are ubiquitous parts of tea plantations of the Terai region. However, their shed leaves might have an effect on the soil microflora under those shade trees, so it is important to find out how leaf litter affect the soil microflora. Isolation of soil microbial consortia followed by downstream experiments were conducted to observe the tolerance/susceptible pattern of those soil microflora against the fallen leaves. Sample from under Albizia odoratissima has higher organic carbon, organic matter and nitrogen content but the same property was found to be low in the sample collected under Melia azedarach. Isolation of consortia was done on nutrient agar. In vitro tolerance assay was conducted to find out the tolerance pattern against leaf extracts, heavy metal salts, pesticides, antibiotics and antifungals. Heavy metals salts like Arsenic trioxide (AS2O3) and Cupric chloride (CuCl2); and pesticides like Thiamethoxam; Spiromesifen; Phorate etc. showed no inhibition against all the isolated consortia. Co-Trimoxazole and Augmentin have not showed any inhibition except consortia under Derris robusta, whereas no antifungals but Itraconazole had an impact over all the consortia. Shade trees, being a crucial member of the tea plantations, cannot be removed but replacement of these with other species could be a probable option, besides this limited use of chemical pesticides and fertilizers should be taken into consideration strictly to restrain the microbial population in tea garden soil. So, this study has disclosed the acceptability of each and every shade tree used in this region.

“…The chromatogram (TIC or Total Ion Chromatogram) is based on the intensity of fragments produced by the ionization. Quantification of the amount (area %) of each compound was done based on peak areas (Majumder et al, 2020;Acharyya et al, 2021). The data obtained from GCMS analysis were further studied from available reported scientific literature to find out responsible growth promoting components or priming agents present in tea waste.…”

Valorization of agro-industrial waste resources is today’s main topic for the agribiotechnology researchers. This research work was designed to valorise tea industrial waste, i.e., manufactured by-products from CTC (crush-tear-curl) tea factory. Physicochemical analysis has been carried out to characterize tea waste treated soil. Pot experiment was considered to study impact of tea waste on plant growth. Morphological parameters such as length of plants and pods, and girth diameter were considered for growth study. Effect of tea factory waste on soil nutrition was found remarkable with increased organic carbon, organic matter, nitrogen, phosphorus, potassium, and sulphur content. Pot culture revealed impact of tea waste composted soil on boosted plant growth. GC-MS based metabolite profiling revealed xanthosine and caffeine as major compounds in tea waste extract. A possible pathway has been proposed to explain the role of xanthosine and caffeine breakdown in fertilization of soil and plant growth. Disposal of tea wastes produced during tea manufacturing can be managed in a sustainable manner if this research is implemented industrially. This research portrays a notable nutrient richness in tea waste treated soil. Detection of purine metabolites revealed remarkable fertilizing and plant growth promoting properties of CTC tea waste.

“…The Japanese traditional fermented beverage sake, the distilled liquor awamori (Yamamoto et al ., 2016), and Himalaya's millet-based distilled liquor raksi (Majumder et al ., 2021) are reported to contain this major compound of tongba . It is a taste-modulating compound responsible for the characteristic taste and aroma of various fermented beverages such as beer, wine, and sake (Yamamoto et al ., 2016;Acharyya et al, 2021) . Pyroglutamic acid was also reported in different fermented foods such as sake and soya sauce (Gazme et al ., 2019), the Tanzanian traditional millet-based liquor togwa (Mugula et al ., 2003), and the Korean ethnic rice wine makgeolli (Kim et al ., 2008) .…”

Tongba, a millet-based fermented ethnic drink of the Limbu and other Nepalese-Tibetan communities, is consumed in the highlands of Singalila Ridge of the Himalayas and the adjoining high-altitude places of Nepal, the northern and north-eastern parts of India, and the Tibetan Plateau and is valued for its ethnomedicinal properties. In this research, the GCMS-based metabolite profiling of an authentic sample of tongba was carried out, identifying various bioactive metabolites. Several biologically active components, such as glycoside, amino acids, fatty acids, and other long-chain hydrocarbon derivatives, terpenoids and phenol, were detected in tongba, which have therapeutic properties against various high-altitude illnesses. Probable biosynthesis routes of those compounds in tongba’s broth were also studied, where many similarities were noticed with the Japanese beverage sake. The key finding of this metabolomic investigation was the detection of bioactive ethyl-α-D-glucopyranoside and cyclo(L-Leu-L-Pro) with abundant peak areas, which confirmed tongba’s therapeutic importance in high-altitude illnesses and its metabolomic similarities with sake.
