Biotechnological Utilization of Agro-Industrial Residues and By-Products-Sustainable Production of Biosurfactants.

The importance and interest in the efficient use and valorization of agro-industrial residues and by-products have grown due to environmental problems associated with improper disposal. Biotechnological production processes, including microbial biosurfactant production, represent a sustainable way to utilize agro-industrial residues and by-products, which are applied as substrates in these processes. Biosurfactants produced by microorganisms using renewable resources are a viable alternative to traditional petrochemical surfactants and have several potential uses in a wide range of industrial sectors due to their minimal ecotoxicity, easy biodegradability, and moderate production conditions.

Production of Trichoderma harzianum K179 bioagent for maize diseases control: complete laboratory stage bioprocess development.

Aims: In order to be competitive on the market, the production of biopreparations needs to be optimized, modelled, and assessed in the early stages of its development. The aim of this paper was to optimize medium for the production of Trichoderma harzianum K179 biocontrol agent, to analyze its kinetics at enlarged laboratory scale and finally economic analysis of the production of this high-value product through simulation modelling.

Methods And Results: The results showed that the bioprocess of T.

Biotechnological Production of Sustainable Microbial Proteins from Agro-Industrial Residues and By-Products.

Microbial proteins, i.e., single-cell proteins or microbial biomass, can be cultivated for food and animal feed due to their high protein content and the fact that they represent a rich source of carbohydrates, minerals, fats, vitamins, and amino acids.

Process model economics of xanthan production from confectionery industry wastewaters.

In this research a process and cost model for a xanthan production facility was developed using process simulation software (SuperPro Designer). This work represents a novelty in the field for two reasons. One is that xanthan gum has been produced from several wastes but never from wastewaters from confectionery industries.
