Abstract The production of bioproducts from microorganisms is a common practice in many industries for long time now. In recent years, studies have proved that co-culturing increase the yield products by synergistically degrading solid substrate comparison with individual cultures. review highlights benefits using state fermentation (SSF) to achieve higher productivity. Filamentous fungi genus ...

The aim of this work is to demonstrate the role of conidial spores as a reservoir of glucose oxidase and their stability as a biocatalyst in the bioconversion reaction for the production of gluconic acid. Solid-state fermentation (SSF) was carried out in fixed-bed column bioreactor for the production of Aspergillus niger spores. Growth parameters, sporulation and kinetics of gluconic acid produ...

Ricinus communis L. is of great economic importance due to the oil extracted from its seeds. Castor oil has been used for pharmaceutical and industrial applications, as a lubricant or coating agent, as a component of plastic products, as a fungicide or in the synthesis of biodiesel fuels. After oil extraction, a castor cake with a large amount of protein is obtained. However, this by-product ca...

The viability of converting biomass into biofuels and chemicals still requires further development towards the reduction of the enzyme production costs. Thus, there is a growing demand for the development of efficient procedures for selection of cellulase-producing microorganisms. This work correlates qualitative screening using agar plate assays with quantitative measurements of cellulase prod...

High cost of poly-3-hydroxybutyrate production remained a major hindrance for its wide range applications. In the current study poly-3-hydroxybutyrate producing bacteria were isolated from environmental sources. Highest poly-3hydroxybutyrate producing isolate Bacillus cereus PS 10 was investigated for its ability to use wide range of low-cost carbon sources including agro-industrial residues, v...

Surfactants are multipurpose products found in most sectors of contemporary industry. Their large-scale manufacturing has been mainly carried out using traditional chemical processes. Some the species involved their production considered hazardous and some industrial processes employing them categorised as “having potential negative impact on environment”. Biological surfactants have therefore ...

The present manuscript reviews the findings of different research studies that evaluate use fungal solid-state (SSF) and submerged culture fermentation (SCF) with agro-industrial residues as substrates to enhance production polyphenols their possible uses food additives. Some (peels, pulps seeds) are an important source phenolic acids (p-coumaric, p-hydroxybenzoic, chlorogenic, cinnamic, feruli...

Enzymes are among the most important products obtained for human needs through microbial sources. A large number of industrial processes in area industrial, environmental and food technology utilize enzymes at some stage or another; Solid State Fermentation (SSF) holds tremendous potential production enzymes, especially those where crude fermented product may be used directly as enzyme source. ...

Cellulase and xylanase have been widely studied for bioconversion processes applied in various industries. The high cost of these enzymes remains to be the major bottleneck large-scale commercial application lignocellulosic biorefinery. use agroindustrial residues weeds as fermentation substrates is an important strategy increase cellulolytic production reduce costs. Penicillium crustosum was n...
