During biodegradation, microorganisms can directly metabolize surfactants for energy and nutrients or co-metabolize them with other compounds. Maximum growth of the bacterial consortium on SDS was seen between 30 35 °C, while optimal pH range 6.5 7.5. As nitrogen source, 2 g/L ammonium sulfate optimum in supporting SDS. The greatest rate recorded at a concentration 1 1.5 (p<0.05). At 2–3, SD...

Tetanus merupakan penyakit yang disebabkan oleh kuman Clostridium tetani. Penyakit ini termasuk mematikan di negara berkembang. Melihat masih tingginya kasus tetanus berkembang serta untuk memberikan pelayanan terbaik dan pengobatan efektif terhadap pasien terkena tetanus, maka diperlukan optimalisasi pada proses pembuatan serum anti sehingga dapat meningkatkan kapasitas produksi kualitas dihas...

Surfactants are adaptable amphiphilic compounds have an especially distinctive polar hydrophilic head and non-polar tail group. The surfactant is extensively used in each walk of life such as care products, domestic cleaners, pharmaceuticals, oil recovery, food handling, nanotechnologies due to decreasing the interfacial tension,. Micellization anionic surfactants potassium dodecyl sulphate (KD...

beta-N-Acetylhexosaminidase from boar epididymis was separated into two forms, A and B, on DEAE-cellulose. Both these forms were excluded from Sepharose S-200 and had apparent Mr values of 510 000 on gradient gel electrophoresis under non-denaturing conditions. Affinity chromatography on 2-acetamido-N-(6-aminohexanoyl)-2-deoxy-beta-D-glucopyranosylam ine coupled to CNBr-activated Sepharose 4B w...

Alpha2-M (alpha2-macroglobulin) was purified from human plasma by two different procedures. As well as having no detectable impurities by the usual criteria for testing the homogeneity of protein preparations, these alpha2M preparations showed a single component, after reduction in urea, of 185000 daltons by sodium dodecyl sulphate/polyacrylamide-gel electrophoresis. The molecular weight of the...
