Abstract

Phytoremediation consists in treating environmental pollutions through the use of plants and their associated microbes. Phytoremediation can be used for pollutant stabilization, extraction, degradation or volatilization. Cadmium is one of the most toxic trace metallic elements for living organisms and its accumulation in the environment is recognized as a worldwide concern. Plants suitable for efficient pollutant extraction from the soil should combine different characteristics like fast growth, high biomass, high tolerance and high accumulation capacities in harvestable parts. Several studies haveshown that plants can accumulate Cd in the body such as Eichornia crassipes, Brassica napus, Avicenna marina, Lycopersicon esculentum, Wolffia globosa, Phytolacca Americana, Solanum nigrum, Typha domingensis, Sedum plumbizincicola, Thlaspi caerulescens, Helianthus annuus,Lolium perenne, Tagetes erecta, Chara australis, Jatropha curcas, Sedum alfredii, Atriplex halimus,Phragmites cummunis, Nitella opaca, Phragmites australis, Typha angustifolia, Cyperus esculentus, Chara aculeolata, Ricinus communis, Hibiscus cannabinus, Zea mays, Arabidopsis halleri, Arundo donax, and Vetiveria zizanioides.Keywords: Cadmium, Phytoremediation, Plant

Abstract

Bakteri Asam Laktat (BAL) yang berpotensi sebagai kandidat probiotik umumnya memiliki kemampuan menurunkan kadar kolesterol. Penelitian ini bertujuan untuk mengetahui kemampuan BAL asal dangke yaitu Lactobacillus fermentum dan Lactobacillus acidophilus untuk menurunkan kadar kolesterol secara in vitro. Penelitian ini menggunakan rancangan acak lengkap (RAL) dengan 4 perlakuan yaitu Ly0 (kontrol yang terdiri dari MRS + 0,1% kolesterol murni + 0,3% oxgal), Ly1 (Media MRS + L. Fermentum), Ly2 (Media MSR + L. Acidophilus) dan Ly3 (Media MSR + L. fermentum + L. acidophilus) dan 3 kali ulangan. Hasil sidik menunjukkan bahwa kadar kolesterol perlakuan berbeda sangat nyata dengan kontrol. Uji lanjut beda nyata terkecil menunjukkan bahwa perbedaan terjadi antara perlakuan Ly0 dengan ketiga perlakuan lainnya, sedangkan antara perlakuan Ly1, Ly2 dan Ly3 tidak berbeda nyata atau dapat dikatakan bahwa penambahan BAL yang diinokulasikan ke dalam media MRS dapat menurunkan kadar kolesterol secara signifikan namun pengaruh jenis/komposisi tidak mempengaruhi secara nyata. Hasil analisis dan uji lanjut juga menunjukkan bahwa penurunan tertinggi ditunjukkan oleh perlakuan Ly3. Hal ini mengindikasikan bahwa BAL asal dangke yaitu L. fermentum dan L. acidophilus memenuhi salah satu kriteria sebagai kandidat probiotik.Kata Kunci: Bakteri Asam Laktat (BAL), Dangke, In Vitro, kolesterol, probiotik
