: Archidendron jiringa seed peel extract was used to aid the coagulation-flocculation process to ultimately remove lead from synthetic residual water. The effectiveness of this method was studied to obtain an alternative approach that is easy to be handled with low cost and energy in removing the lead from residual water. Optimum parameters were analyzed to determine the effectiveness of lead removal, including pH, alum dose, and A. jiringa seed peel extract dose. A study on the coagulation-flocculation process with and without the aid of A. jiringa was also conducted. The optimum pH, the alum dose, and the A. jiringa seed peel extract dose were 9.0, 2.44 g / l, and 60.2 mg / l, respectively. The percentage of lead removal with the aid of A. jiringa seed peel extract was 79%, and the percentage was dropped to only 47% without the extract. A significantly higher rate in the coagulation-flocculation process due to the presence of A. jiringa seed peel extract proved its effectiveness in removing lead from wastewater.
:采用鸡苓籽皮提取物辅助混凝-絮凝工艺，最终去除合成残水中的铅。研究了该方法的有效性，以获得一种易于操作、低成本、低能耗的除铅方法。通过对pH、明矾用量、木林子皮提取物用量等参数的分析，确定了木林子皮提取物对铅的去除效果。并对加、不加牛蒡的混凝-絮凝过程进行了研究。最适pH为9.0 g / l，明矾用量为2.44 g / l，木参籽皮提取物用量为60.2 mg / l。加枸杞籽皮提取物对铅的去除率为79%，不加枸杞籽皮提取物的去除率仅为47%。在混凝-絮凝过程中，栀子皮提取物的去除率显著提高，证明了其对废水中铅的去除效果。

Microbiome is known to exist as symbiotic commensals in humans, domestic and wild animals, birds, fishes, reptiles, insects etc. DNA sequencing and metagenomic platforms have deciphered the complex role played by communities of microbiota (bacteria, fungi, viruses, protozoa and other eukaryotic species) in survival and regulation of host physiology, metabolism and regulation of host immune system. Any alteration in the microbial population or breach in the symbiotic alliance with the host may ultimately lead to development of different kinds of pathologies. Realization of the enormous role played by the microbiome in health and diseases of human and domestic livestock led researchers to find ways to modulate these resident microbiomes for improvement in health and management of diseases. Theoretically there are several ways that can be employed for manipulating the composition and functional capacity of the resident microbiome, which may lead to improvements in human and livestock health. Though studies have shown therapeutic potential of the microbiome, considerable challenges exist in the actual implementation of these strategies in clinical settings. This review discusses the symbiotic relationship between microbiome and host and strategies to modulate host immune responses by manipulating microbiome profile. Paper also highlights how to overcome existing obstacles for successful implementation of microbiome manipulation techniques. In this era of COVID-19, it would be worth analysing the role of resident microbiome in the magnitude of COVID-19 severity which may have occurred through immunomodulation.
