Physico - chemical characteristics of the collected tannery effluent was analyzed. The tannery effluent was acidic nature with brown colour and emitted unpleasant smell. High value of TSS and TDS and BOD and COD, calcium, magnesium, sodium, potassium, fluoride, nitrate, nitrite, sulphate and the toxic heavy metals chromium, nickel, zinc, copper and iron were recorded in the collected tannery effluent sample. Ten different bacterial isolates \u003ci\u003eviz\u003c\/i\u003e., \u003ci\u003ePseudomonas \u003c\/i\u003e sp. \u003ci\u003e \u003c\/i\u003e(P1), \u003ci\u003e Proteus\u003c\/i\u003e sp., \u003ci\u003eBacillus \u003c\/i\u003esp., \u003ci\u003e Escherichia\u003c\/i\u003e sp.\u003ci\u003e, Serratia \u003c\/i\u003esp., \u003ci\u003ePseudomonas \u003c\/i\u003esp.\u003ci\u003e \u003c\/i\u003e(P2)\u003ci\u003e, Staphylococcus \u003c\/i\u003esp.\u003ci\u003e, Enterobacter \u003c\/i\u003esp., \u003ci\u003eAlcaligenes \u003c\/i\u003esp., \u003ci\u003eMicrococcus \u003c\/i\u003esp. and \u003ci\u003eStaphylococcus\u003c\/i\u003e sp. were identified. The bacterial isolates were screened for its resistance against toxic heavy metals. All the ten isolate were resistant to all the heavy metals. Heavy metal adsorption by living bacterial cells (Bioaccumulation), dead bacterial cells (Biosorption) and immobilized bacterial cells (Immobilization) was studied. Immobilized (Sodium alginate) bacterial cells were considered as the best was for the bioremediation of heavy metals. The bacterial isolates which were identified in genus level were subjected to 16S rRNA sequencing and identified in species level. The bacteria \u003ci\u003eBacillus\u003c\/i\u003e sp. confirmed as was confirmed as \u003ci\u003eBacillus subtilis\u003c\/i\u003e, \u003ci\u003eSerratia\u003c\/i\u003e sp. was confirmed as \u003ci\u003eSerratia marcescens\u003c\/i\u003e and\u003ci\u003e Pseudomonas \u003c\/i\u003esp. was confirmed as \u003ci\u003ePseudomonas fluorescens.\u003c\/i\u003e The bacterial isolate \u003ci\u003eBacillus subtilis\u003c\/i\u003e, \u003ci\u003eSerratia marcescens\u003c\/i\u003e, \u003ci\u003ePseudomonas fluorescens \u003c\/i\u003ewere selected for optimization study based on heavy metal adsorption. The collected tannery effluent was inoculated with (immobilized beads) 5 per cent inoculum containing \u0026gt;105 cfu\/ml of bacterial consortium (\u003ci\u003eBacillus subtilis\u003c\/i\u003e + \u003ci\u003eSerratia marcescens \u003c\/i\u003e+ \u003ci\u003ePseudomonas fluorescens\u003c\/i\u003e), and air was passed continuously using an aerator. After 6 months, the sample was filtered under aseptic condition and physico - chemical parameters were estimated. The colour of the bioremediated tannery effluent sample was black to colourless and odorless. The physico - chemical characteristics of the bioremediated tannery effluent was significantly reduced after 6 month\u003cbr\u003e\u003cbr\u003e\u003cb\u003eAuthor:\u003c\/b\u003e Hanan Selman Hessan\u003cbr\u003e\u003cb\u003eISBN-10:\u003c\/b\u003e 9391342094\u003cbr\u003e\u003cb\u003eISBN-13:\u003c\/b\u003e 9789391342098\u003cbr\u003e\u003cb\u003ePublisher:\u003c\/b\u003e JPS Scientific Publications, India\u003cbr\u003e\u003cb\u003eLanguage:\u003c\/b\u003e English\u003cbr\u003e\u003cb\u003ePublished:\u003c\/b\u003e 10\/15\/2021\u003cbr\u003e\u003cb\u003ePages:\u003c\/b\u003e 100\u003cbr\u003e\u003cb\u003eFormat:\u003c\/b\u003e Paperback\u003cbr\u003e\u003cb\u003eWeight:\u003c\/b\u003e 0.56lbs\u003cbr\u003e\u003cb\u003eSize:\u003c\/b\u003e 11.00h x 8.50w x 0.21d","brand":"Hanan Selman Hessan","offers":[{"title":"Paperback","offer_id":46721386807551,"sku":"9789391342098","price":13.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0662\/2982\/9887\/files\/img_75ab458f-8bfd-4c70-892b-ae5ebc4aec08.jpg?v=1742752716","url":"https:\/\/www.whiterainbookhouse.com\/products\/bacterial-bioremediation-of-heavy-metals-hanan-selman-hessan-9789391342098","provider":"WR Book House","version":"1.0","type":"link"}
