Abstract

Límbah cair industri tempe bersifat biodegradable, sehingga dapat diuraí secara biologi. Pengoløhanyang dÍcobakan adalah sistem biofilm. Percobaan dilakukan dengan mengembangbíakkan Bakteri Bachillus Sphaericus menggunakan nutrisi MRS Broth dalam aquades dan media biofìlm batu apung yang dimasukkan dalam limbah. Laju pertumbuhan bakteri diamati pada variasi suhu 29C, 40C, 50C dan 60C pada fase pertumbuhan cepat. Hasil analísís data dengan pendekatan bahwa reaksi yang terjadimengikuti reaksi katalitik orde satu diperoleh persamaan laju pertumbuhan mikroba sebagai fungsi suhu sebagai r= 1,75 x 10^8 e^(-13.2/RT)xS.

Abstract

Plastics have important roles nowadays. However, its non-biodegradable property potentially makes a great problem because of the accumulation of its waste. Therefore, many researches about biodegradable plastics have been developed. Poly-β-hydroxybutyrate (PHB) is an alternative material to produce biodegradable plastics. The objectives of this research are to study the production of PHB by using Bulkhoderia cepacia bacteria and soluble starch substrate and determine the kinetics parameters including maximum specific growth rate (μmaks), saturation constant (Ks), and yield ratio of product-to-bacterial cell (YP/X). Fermentation was conducted at room temperature by using Ramsay medium with soluble starch at certain concentrations. The starter of Bulkhoderia cepacia incubated for 24 hours was inoculated as many as 10% by volume. The PHB product and dry cell weight were analyzed at certain several time intervals. This experiment was repeated at variation of phosphate concentrations.This research showed that the optimum cell growth and PHB production was obtained at soluble starch concentration of 8 g/100 ml and growth period of 72 hours. At this condition, the results were the dry cell weight of 7.5 mg/ml and PHB concentration of 0.0095 mg/ml. The values of kinetics parameters were μ maks of 0.01292 g/ml. h, Ks of 0.2854 g/ 100ml, YP/X of 0.00143. The accumulation of PHB was optimum at limited phosphate concentration. It could be also concluded that Bulkhoderia cepacia was a non-effective bacteria to produce PHB.

Abstract

This paper presents a mathematical model for the performance of a non-ìdeality plugflow reactor. An analytical technique used was the residence time distribution (RTD) involving tracer component. This model can give a prediction of the number of the ideal continuous stirred tank reactors that could represent the non-ideal plug flow reactor. Regardíng to the literature, the result obtained is 9 continuous stirred tank reactors in series would represent the performance of non-ideal plugflow reactor that was analyzed
