“…The results indicate that the bed depth also affected the temperature control in PBSSB. These results are in qualitative agreement with Chen, Xu & Li [8], Fanaei & Vaziri [9], Castaneda, Rojas, Bacquet, Raimbault & Gonzalez [10] and Srinophakun & Srinophakun [11]. Chen, Xu & Li [8] developed the bioreactor for solid-state fermentation (SSF) and performed the temperature gradient studies with different bed heights.…”

The packed bed solid state bioreactor designated as PBSSB is constructed in the present study. The experiments are carried out in packed bed bioreactor with jowar straw and inoculated with Aspergillus oryzae. Temperature gradient has been measured at different axial positions. It is found that the organisms grew rapidly during the period from 20 to 30 h during which heat generation is more. These results are in agreement with other researchers. The fermented jowar straw shows threefold increase in protein content. This can be utilized as high value nutritional feed to animals.

“…Another concern was the temperature gradient occurring throughout the bed. Chen et al (2005) have placed probes in the trays every 3 cm bed height (0, 3, 6 and 9 cm) from the bottom to the top of the bed. With this method, they have observed nearly 2.5 C medium temperature difference between 0 and 6 cm levels of the bed (with the air pulsation method).…”

a b s t r a c tWheat bran was tested as the solid substrate for the tray-type solid-state fermentation (SSF) production of polygalacturonase (PG) enzyme by A. sojae mutant strain e a high-PG activity producer. PG production of A. sojae was found to reduce as the thickness of the substrate increase from 8 mm to 14 mm at 90% relative humidity. An interaction between the thickness of the bed and relative humidity of the environment was determined with the help of experimental design and statistical analysis tools. As a result, the PG activity could be enhanced by 31% as the process conditions optimized. Additionally, 11 mm thickness and 70% relative humidity were selected as the PG production favoring conditions with the maximum PG activity of 298 U/g substrate in tray type of SSF without the addition of any nutritive or inducing supplements into wheat bran. The kinetic study conducted in the trays revealed the presence of reduction in the water activity on the 4th day of the SSF process under stated conditions. The productivity of the process conducted under optimized conditions was 3.41 U/g substrate À1 h À1 for the 4th day of the SSF.

“…Rathbun and Shuler (1983) found out that during tempeh fermentation the temperature gradients as high as 3°C cm -1 and O 2 gradients of 1.7% (v/v) have been detected. However, Chen et al (2005) have successfully developed a newly and effective bioreactor which can enhance the heat transfer and effectively control the temperature variation in SSF process. By using two dynamic changes of air during fermentation developed by the authors, the maximum temperature difference at a height bed of 9.0 cm was only 0.12°C cm -1 compared with traditional tray SSF system where the temperature gradient was more than 3°C cm -1 at a bed height of 6.5 cm.…”
