Kinnow mandarin (Citrus reticulata) peel, an agricultural solid waste of the juice processing industry, was studied to understand mass transfer kinetics during osmotic dehydration and its process optimization. The experiments were conducted in sucrose (40, 50, 60° Brix) at different temperatures 40, 60°C duration 0–240 min. Central Composite Design used for optimization with variables, such as ...

We tested recent evidence that ischemic preconditioning (PC) involves in translocation of protein kinase C (PKC) from the cytosol to myocyte membrane. Isolated Langendorff-perfused rabbit hearts (n=96) were subjected to 60 or 45 min of ischemia (I) and 120 min of reperfusion (R) with or without PC (4 cycles of 5 min I and 5 min R; or single dose of 5 min I and 10 min R), respectively. Left vent...

This study demonstrates the applicability of pressurized stirred tank bioreactors for oxygen transfer enhancement in aerobic cultivation processes. The specific power input and the reactor pressure was employed as process variable. As model organism Escherichia coli, Arxula adeninivorans, Saccharomyces cerevisiae and Corynebacterium glutamicum were cultivated to high cell densities. By applying...

as a-D-mannosyl-(l -# 3')-diglyceride and a-D-mannosyl-(l 3)-a-D-mannosyl(1 3')-diglyceride.1 In this communication, the results of studies on the structure of the third mannose-containing lipid are presented. All the available evidence indicates that the structure of this compound is mannosyl-1-phosphorylpolyisoprenol (MPP). Preliminary experiments suggest that IMPP serves as an intermediate i...

Young children's activity and sedentary time were simultaneously measured via the Actical method (i.e., Actical accelerometer and specific cut-points) and the ActiGraph method (i.e., ActiGraph accelerometer and specific cut-points) at both 15-s and 60-s epochs to explore possible differences between these 2 measurement approaches. For 7 consecutive days, participants (n = 23) wore both the Acti...

Three semicontinuous continuous stirred-tank reactors (CSTR) operating at mesophilic conditions (35°C) were used to investigate the effect of hydraulic retention time (HRT) on anaerobic digestion of wheat straw. The results showed that the average biogas production with HRT of 20, 40, and 60 days was 46.8, 79.9, and 89.1 mL/g total solid as well as 55.2, 94.3, and 105.2 mL/g volatile solids, re...
