Abstract

The rapid expansion of textile industry in Indonesia raises substantial concerns with regard to the disposal of excess dyes into the environment. The deleterious consequences of such issue can be alleviated through wastewater management by combining physical, chemical and biological approach. Biological treatment through bioremediation needs to be thoroughly considered and developed as it offers favorable attributes by being sustainable, inexpensive and environmentally friendly. In Indonesia, the employment of bioremediation technique, to treat textile dye effluent, has been extensively applied through the use of activated sludge. Apparently, studies describing the potential of various indigenous microorganisms to degrade textile dyes have continuously been reported. This paper proposed practical methods to isolate and select for potential indigenous microbes as well as their employment as bioremediation agent on dye contamination. Selections can be enhanced through the incorporation of bioinformatics analysis on the approach of microbiology. Appropriate systems are required to be carefully designed to optimized application on-site.

Abstract

Probiotics are a group of bacteria with health benefits, which are widely used in various nutritional products. Various efforts are made to effectively increase growth of probiotics, including adding supplemental nutrition, such as protein. In this study, a series of tests were conducted (optical density, colony forming unit, and pH test) to evaluate the effect of collagen hydrolysate supplementation, obtained from tuna waste, on the growth of Bacillus subtilis G8, a candidate of probiotic bacteria which have been isolated from the Japanese traditional food natto. The results demonstrated positive impacts of collagen hydrolysate supplementation on cell density and colony-forming units, as well as on the reduction of pH of bacterial growth medium. Concentration of 5% was observed as the most optimum concentration to support the bacterial growth, while the most acidic pH of bacterial growth medium is observed at 3% supplementation. In conclusion, supplementation of collagen hydrolysate derived from tuna waste supported the growth of B. subtilis G8 as well as reduced the pH of its growth media. Bahasa Indonesia Abstract: Probiotik merupakan sekelompok bakteri yang memiliki manfaat kesehatan dan banyak digunakan dalam berbagai produk nutrisi. Beragam upaya telah dilakukan untuk secara efektif meningkatkan pertumbuhan probiotik, salah satunya melalui penambahan nutrisi tambahan seperti protein. Dalam penelitian ini, serangkaian uji dilakukan, meliputi uji kerapatan optik, unit pembentuk koloni (CFU), dan pengukuran pH, untuk mengevaluasi pengaruh suplementasi kolagen hidrolisat yang diperoleh dari limbah ikan tuna terhadap pertumbuhan Bacillus subtilis G8, yakni kandidat bakteri probiotik yang diisolasi dari makanan tradisional Jepang, natto. Hasil penelitian menunjukkan bahwa suplementasi kolagen hidrolisat memberikan dampak positif terhadap kerapatan sel dan jumlah koloni, serta menyebabkan penurunan pH medium pertumbuhan bakteri. Konsentrasi 5% diketahui sebagai konsentrasi yang paling optimal dalam mendukung pertumbuhan bakteri, sedangkan pH terendah pada medium pertumbuhan tercatat pada konsentrasi suplementasi sebesar 3%. Dengan demikian, dapat disimpulkan bahwa suplementasi kolagen hidrolisat yang berasal dari limbah ikan tuna mampu mendukung pertumbuhan B. subtilis G8 serta menurunkan pH media pertumbuhannya.
