Citric acid has high economic potential owing to its numerous applications. It is mostly produced by microbial fermentation using Aspergillus niger. In view of surges in demand and growing markets, there is always a need for the discovery and development of better production techniques and solutions to improve production yields and the efficiency of product recovery. To support the enormous scale of production, it is necessary and important for the production process to be environmentally friendly by utilizing readily available and inexpensive agro-industrial waste products, while maintaining high production yields. This article reviews the biochemistry of citric acid formation, choices of citric-acid producing microorganisms and raw materials, fermentation strategies, the effects of various fermentation conditions, citric acid recovery options and the numerous applications of citric acid, based on information drawn from the literature over the past 10 years.

“…The solid residue was subjected to chelation and mild hydrothermal treatment in a 2-l Parr reactor with various concentrations of chelating agent for 2 h at 130°C. The degradation temperature of citric acid is 170°C, which can be reduced in a pressurized system [21], so the temperature of 130°C was chosen to avoid the possible degradation of the chelant. Reactor pressure was monitored and was consistently at, or near, the vapor pressure of water (2.7 bar).…”

Lignocellulosic biomass such as corn stover can contain high ash content, which may act as an inhibitor in downstream conversion processes. Most of the structural ash in biomass is located in the cross-linked structure of lignin, which is mildly reactive in basic solutions. Four organic acids (formic, oxalic, tartaric, and citric) were evaluated for effectiveness in ash reduction, with limited success. Because of sodium citrate's chelating and basic characteristics, it is effective in ash removal. More than 75 % of structural and 85 % of whole ash was removed from the biomass by treatment with 0.1 g of sodium citrate per gram of biomass at 130°C and 2.7 bar. FTIR, fiber analysis, and chemical analyses show that cellulose and hemicellulose were unaffected by the treatment. ICP-AES showed that all inorganics measured were reduced within the biomass feedstock, except sodium due to the addition of Na through the treatment. Sodium citrate addition to the preconversion process of corn stover is an effective way to reduced physiological ash content of the feedstock without negatively impacting carbohydrate and lignin content.

There has been considerable increase in interest in the conversion of renewable resources into several essential products (for example, biofuel, amino acids, among others) over the last few years, as the potential impact of global warming is demanding technologies that close the carbon cycle. Utilization of the hemicellulose fraction from lignocellulosic biomass is an important factor to optimize for the economicallyl feasible products. The bioconversion of pentoses derived from hemicellulose remains a bottleneck in developing industrial production, as microbes either preferentially use glucose, or cannot use pentoses at all. Sugar cane bagasse is one of the best candidates to have large amount of hemicelluloses for industrial interest. The aim of this review paper is to study research conducted on pentose utilizing bacteria, a variety of effects during break down of hemicellulose and the industrial importance of those bacteria.
