Exploration of fungal spores as a possible storehouse of proteolytic biocatalysts

Sumantha, A; Fontanille, P; Larroche, C; Pandey, A (Springer, 2008)

Studies were carried out to define the relation between enzyme production and fungal sporulation, in solid-state cultivation conditions of the filamentous fungus Aspergillus oryzae NRRL 2217 to get information on possible ...
Fed-batch production of gluconic acid by Terpene-treated aspergillus niger spores

Sumitra, R; Fontanille, P; Pandey, A; Larroche, C (Springer, 2008)

Aspergillus niger spores were used as catalyst in the bioconversion of glucose to gluconic acid. Spores produced by solid-state fermentation were treated with 15 different terpenes including monoterpenes and monoterpenoids ...
Gluconic acid:Properties, applications and microbial production

Sumitra, R; Fontanille, P; Pandey, A; Larroche, C (Faculty of Food Technology and Biotechnology, 2006)

Gluconic acid is a mild organic acid derived from glucose by a simple oxidation reaction. The reaction is facilitated by the enzyme glucose oxidase (fungi) and glucose dehydrogenase (bacteria such as Gluconobacter). Microbial ...
Permeabilization and inhibition of the germination of spores of Aspergillus niger for gluconic acid production from glucose

Sumitra, R; Fontanille, P; Pandey, A; Larroche, C (Elsevier, 2008)

In this study, the role of citral to permeabilize the spores of Aspergillus niger and replace sodium azide in the bioconversion medium was studied. Further, characterization of glucose oxidase of spores was carried out by ...
Recent developments in microbial oils production: a possible alternative to vegetable oils for biodiesel without competition with human food?

Christophe, G; Vinod Kumar; Nouaille, R; Gaudet, G; Fontanille, P; Pandey, A; Soccol, C R; Larroche, C (2012-01)

Since centuries vegetable oils are consumed as human food but it also finds applications in biodiesel production which is attracting more attention. But due to being in competition with food it could not be sustainable and ...
Spores of Aspergillus niger as reservoir of glucose oxidase synthesized during solid-state fermentation and their use as catalyst in gluconic acid production

Ramachandran, S; Fontanille, P; Pandey, A; Larroche, C (Blackwell Publishing, 2007)

Aims: To exploit conidiospores of Aspergillus niger as a vector for glucose oxidase extraction from solid media, and their direct use as biocatalyst in the bioconversion of glucose to gluconic acid. Methods and Results: ...
Stability of glucose oxidase activity of Aspergillus niger spores produced by solid-state fermentation and their role as biocatalysts in bioconversion reaction

Sumitra, R; Fontanille, P; Pandey, A; Larroche, C (Faculty Food Technology Biotechnology, 2008)

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 ...
