Hermetia illucens is an important species for waste management and the circular economy. The aim of this study was to analyze effects Trichoderma reesei C2A Pleurotus sp. as pretreatments brewer spent grain (BSG). BSG inoculated with fungal solution or distilled water (control). After seven days, used H. larvae cultivation. At end bioconversion process, parameters substrate reduction larval dev...

Using resting cells of Rhodococcus rhodochrous J1, in which a large amount of nitrilase is induced, a simple and efficient bioconversion process for the production of pyrazinoic acid, an antimycobacterial agent, through catalysis by a nitrilase was developed. The reaction conditions for production of pyrazinoic acid were optimized. Under optimum conditions, 3.5 M cyanopyrazine was converted to ...

Increasing interest in lipases has been observed at the end of the last century, due to their potential application, in (bio)degradation as well as in (bio)synthesis of glycerides. The advantages of the enzymatic hydrolysis over the chemical process consist of less energy requirements and higher quality of the obtained products. Beside this, lipases are also efficient in various reactions such ...

Biodegradable polymers such as polyhydroxybutyrate (PHB) are part of the emerging portfolio of renewable materials, which are addressing the issue of plastic waste. Syngas, as a cheap, renewable and sustainable resource that can be obtained from biomass or waste, is viewed as an excellent feedstock for different bioprocesses, including syngas to PHB bioconversion. However, due to the hazardous ...

injection molding is the most widely used process for producing plastic parts.in this process, an important issue is to predict and optimize the warpage before manufacturing. in this paper, a simulation with moldflow software is proposed to optimize the injection molding process. the optimization process aims at minimizing the warpage of the critical injection molding part in which process para...

BACKGROUND Red ginseng is prepared by steaming raw ginseng, a process believed to increase the pharmacological efficacy. Further bioconversion of red ginseng through fermentation is known to increase its intestinal absorption and bioactivity, and bioconversion diminishes the toxicity of red ginseng's metabolite. This study was conducted to investigate the effects of daily supplementation with f...
