Abstract In this study, Bioconversion process of glucose to fructose from date syrup using Escherichia coli K12 is modeled using a commercial computational fluids dynamics (CFD) code fluent FLUENT 6.3.23 [8] which we implemented a user-defined functions (UDF) to simulate the interrelationships at play between various phases. A two phases CFD model was developed using an Eulerian – Eulerian approach to calculate the fructose volume fraction produced during time. The bioconversion process was studied as function of three initial concentration of glucose (0.14, 0.242 and 0.463gL–1), three induction time (60, 120 and 180 mn) and three inoculum volume (100, 120 and 150mL). The numerical results are compared with experimental data for bioconversion rate and show good agreement (R2= 0.894). The optimal condition of diffusion was obtained by applying an initial concentration of glucose less than 0.2gL–1 and induction time great than 100 minutes.

Abstract Green-glazed jars were manufactured in southern Iraq during the Parthian, Sasanian, and early Islamic periods. In the latter period, they were distributed in great numbers in the Near East and in coastal areas along the Indian Ocean from the Horn of Africa to China and Japan. The jars are thought to have been used chiefly for storing “date-syrup.” Around the 4th/10th century their production was significantly reduced and their prevalence greatly declined, a phenomenon that has puzzled archeologists. In this study, I identify these jars with “the green jars” (al-jarr al-akhḍar or ḥantam) mentioned in some classical Islamic texts. According to numerous Ḥadīth, the Prophet prohibited nabīdh (date-wine) in “green jars.” While many Muslim jurists held that the Prophet withdrew this prohibition and that these jars were lawful, many found the use of these jars reprehensible or even forbidden. I suggest that the Ḥadīth in which the Prophet prohibited green jars may have contributed to the decline of green-glazed jars.
