“…This is in line with Mouafo et al [41], who reported an 81% ± 1.14% emulsification index with sugar cane molasses as a carbon source for biosurfactant production by Lactobacillus strains. The use of molasses as a carbon source in fermentation medium increased rhamnolipid production by P. fluorescens [42]. On the screening of different nitrogen sources for biosurfactant production, sodium nitrate gave the highest biosurfactant yield (88.3% ± 1.5%) with CGA1 ( Figure 3).…”

Biosurfactants are biomolecules produced by microorganisms, which possess several advantages over their chemical counterparts. Production can be cost-effective if renewable wastes are utilized as substrates. In this study, optimization of biosurfactant production by Pseudomonas aeruginosa strain CGA1 was carried out using response surface methodology. The conventional "One factor at a time" method of optimization was initially adopted to ascertain the impact of different renewable wastes on biosurfactant production. Four independent variables were tested: carbon and nitrogen concentration, medium volume, and inoculum size. Biosurfactant production was based on the emulsification index measurement. Results indicated that the preferred carbon source by the isolate was sugar cane molasses. A 2.31-fold increase in biosurfactant yield and emulsification index of 96.3% ± 0.75% under optimized cultural conditions of 20 g/L of molasses, 5 g/L of sodium nitrate, 1.93 ml inoculum size and 60 ml medium volume in 250 ml conical flask were obtained. The regression coefficient (R 2) value of 84.15% implied adequate fitness of the model. The surface tension of distilled water was reduced from 72.1 mN/m to 35.0 ± 0.0 mN/m, and critical micelle concentration was attained at 60 mg•L −1. FTIR and GC-MS analysis indicated that the biosurfactant was a lipopeptide having characteristic lipid and peptide peak values. This study proves that the sole use of agro-industrial wastes for the production of biosurfactant is very efficient, and ensures the economic feasibility of biosurfactant production.

Water treatment of tapioka and tofu wastewater was studied. Water treatment was conducted by coagulation process by winged bean (Psophocarpus tetragonolobus) seed powder which was followed by adsorbstion by natural active zeolite. The changing of turbidity, DO and pH during water treatment were investigated. Turbidity of tapioca wastewater which was initially 798 FNU, decreased to 57 FNU. Increasing of tapioca wastewater DO value was obtained from 1.20 to 5.92 ppm. Increasing pH tapioca wastewater was also observed from 5.8 to 6.7. Similar results were obtained for tofu wastewater. Turbidity of tofu wastewater which was initially 680 FNU, decreased to 37 FNU. Increasing of tofu wastewater DO value was obtained from 1.67 to 6.61 ppm. Increasing pH tofu wastewater was also observed from 4.7 to 6.7. Results showed that the improvement qualities of tapioca and tofu wastewater was achieved which meet wastewater quality standard by Minister of Environment of the Republic of Indonesia.

“…Biosurfactants have been applied for agrochemical solubilization, emulsification, and foaming in food processing and phase dispersion for cosmetic and textiles. Biosurfactants also have potential environmental applications for bioremediation, oil spills control, crude oil transferring and oil recovery enhancement [1][2][3].…”

The batch removal of Cu(II), Cd(II) and Pb(II) adalah berturut-turut 0,169; 0,276; and 0,323 ABSTRAK Pengambilan ion logam Cu(II), Cd(II) dan Pb(II) dengan metode batch dari larutan menggunakan biosurfaktan yang diproduksi oleh Pseudomonas aeruginosa menggunakan minyak jagung sebagai substrat telah dipelajari. Proses pengambilan ion logam oleh biosurfaktan yang belum dimurnikan tergantung oleh pH awal dan waktu kontak. Pengambilan ion logam berat dalam larutan mempunyai kondisi optimum pada pH awal larutan 6,0 dan waktu kontak 10 menit. Urutan kekuatan pengambilan ion logam berat oleh CPB adalah Pb(II)>Cd(II)>Cu(II). Biosurfaktan mempunyai kapasitas pengambilan untuk logam Cu(II), Cd(II) dan Pb(II) dari larutan logam tunggal
