“…Reaction order 0 and reaction order 1 were not used in this study because both graphs show that biomass x time (xt) has no effect on TPH removal, and is not in accordance with this study. The modeling of the relationship between the substrate and the concentration of bacteria obtained from this kinetic calculation can be used to estimate the degradation process periodically on a pilot scale [33,34]. The results of this laboratory-scale research are planned on a larger scale or pilot scale to treat 1000 L of oilcontaminated water by utilizing Acetobacter tropicalis and Lactobacillus casei bacteria consortium.…”

The objective of this research is to remove Total Petroleum Hydrocarbon (TPH) contained in crude oil by utilizing Acetobacter tropicalis and Lactobacillus casei bacteria consortium through degradation process. Crude oil degradation was conducted on Stone Mineral Salt Solution (SMSS) liquid media and artificial sea water in a controlled environment with limited system. The implemented variations on SMSS liquid media are differentiated based on acidity (pH) of 3, 5, and 7, with contact time of 7, 14, and 21 days. On the other hand, the variation implemented on artificial sea water only applied on contact time of 7, 14, and 21 days. Samples were incubated on a shaker incubator with 30°C and 150 rpm. The sensitivity test revealed that consortiom bacteria are resistant against crude oil, which proven by the missing inhibiting zone formation around disc paper that contains crude oil. This research shows that the optimum condition to degreade TPH both on SMSS liquid media and artificial sea water is at pH level of 7 in 7 days with TPH removal efficiency of 94%. This research provides an important information that Acetobacter tropicalis and Lactobacillus casei bacteria consortium has the potential to degrade crude oil TPH in a controlled environment.

“…This states that the larger the concentration of the drug greater will be the elimination rate. In other words, the process does not become saturated and inhibits the accumulation of the drug form the body (Wang, Qin, & Witarsa, 2018). 1st order elimination dynamics are responsible for the elimination of 95 percent of the medication that is used therapeutically.…”

Biological half-life and volume of distribution of the drug are the key parameters in understanding the pharmacokinetics of the drugs within the body as they affect all the pharmacokinetic processes including absorption, distribution, metabolism and elimination of drugs and also associated with each other, ultimately effecting the Pharmacological action of the drug on its target site. Given study elaborates the various aspects of half-life, i.e., Alpha & beta half-lives, the contribution of Zero-order and first-order kinetics in ADME and interrelation among the volume of distribution & half-life along with the distribution & redistribution of the drug within the body. Moreover, the importance of half-life & Vd and the idea of Steady-state concentration is also discussed. Various types of physiological barriers, including the blood-brain barrier, placental barrier, blood-CSF barrier, affect the distribution of drugs.
