Broomcorn seed (Sorghum vulgare) was used as raw material for bioethanol production. Optimum conditions were obtained from response surface method. Broomcorn seed flour (45 g/l) was treated by alkaline treatment and dual enzymatic hydrolysis (0.7 g/l of α- amylase and 0.42 g/l of amyloglucosidase). The hydrolyzed total sugar of 25.5 g/L was used in conventional bioethanol production (8.1 g/l) u...

Staphylococcus aureus (S. aureus), which has developed multidrug resistance, leads to many healthcare-associated infections resulting in significant medical and economic losses. Therefore, the development of new efficient strategies deal with these bacteria been gaining importance. Lysostaphin is a peptidoglycan hydrolase that considerable potential as bacteriocin. However, there have few repor...

Background: The succinic acid demand accelerated through the years. Thus, need to improve production economically is aggravated. fermentation process by succinate bacteria showed promising production. However, due different characteristics, mediums composition and operating conditions, a fixed quantity of cannot be determined or generalized. Recently, raising interest in examining cheap brought...

Controlled fermentation processes have high potential for improving coffee quality. The effect of temperature on beverage quality was investigated with cultivated at elevations between 1166 and 1928 m. A completely randomized design carried out five elevation ranges 200 m intervals in farms per range, two temperatures (15 °C 30 °C), which were maintained a temperature-controlled bioreactor. Eac...

When working with anaerobic bacteria it is important to have the capability perform parallel bioreactor growth experiments that are both controllable and reproducible, although capital consumables costs for commercially available systems often prohibitively high. Hence, a three-vessel system was designed constructed has capabilities batch fed processes can also be set up continuous culture at f...

Fungal strain Trichoderma spp. is a known bio control agent (BCA), which are difficult to obtain using more prevalent industrial-scale biofermentation methods such as submerged fermentation (SmF) However, up-scalable solid-state (SSF) appropriate for BCA production. An automated semi-rotating drum bioreactor was developed and built explore SSF scale-up pea wheat bran substrates valorise food-in...

Microbial conversions are generally inhibited by their products. This product inhibition is particularly dependent on the product’s hydrophobicity and its acid dissociation behaviour, hence pH. Dependence microbial strain relatively modest according to many published data. Since has various mechanistic backgrounds, one requires an empirical model for simulation of fermentation processes. For ob...
