A sustainable bioprocess technology for producing food-flavour (+)-γ-decalactone from castor oil-derived ricinoleic acid using enzymatic activity of Candida parapsilosis: Scale-up optimization and purification using novel composite.

Ricinoleic acid (RA) from castor oil was employed in biotransformation of peach-flavoured γ-decalactone (GDL), using a Candida parapsilosis strain (MTCC13027) which was isolated from waste of pineapple crown base. Using four variables-pH, cell density, amount of RA, and temperature-the biotransformation parameters were optimized using RSM and BBD. Under optimized conditions (pH 6, 10 % of microbial cells, 10 g/L RA at 28°C), the conversion was maximum and resulted to 80 % (+)-GDL (4.

Biotransformation of ricinoleic acid to γ-decalactone using novel yeast strains and process optimization by applying Taguchi model.

Flavour molecules are generated now-a-days through microbial fermentation on a commercial scale. γ-Decalactone (GDL) is an important molecule due to its long-lasting flavouring impact as buttery, coconut and peach-type. In the current study, 33 microorganisms were isolated from different fruit sources, and their screening for target GDL production was performed.

Effect of liquiritigenin on chloroquine accumulation in digestive vacuole leading to apoptosis-like death of chloroquine-resistant P. falciparum.

Background: Malaria remains one of the major health concerns, especially in tropical countries. Although drugs such as artemisinin-based combinations are efficient for treating Plasmodium falciparum, the growing threat from multi-drug resistance has become a major challenge. Thus, there is a constant need to identify and validate new combinations to sustain current disease control strategies to overcome the challenge of drug resistance in the malaria parasites.

Production of lactones for flavoring and pharmacological purposes from unsaturated lipids: an industrial perspective.

The enantiomeric pure and natural (+)-Lactones (C ≤ 14) with aromas obtained from fruits and milk are considered flavoring compounds. The flavoring value is related to the lactones' ring size and chain length, which blend in varying concentrations to produce different stone-fruit flavors. The nature-identical and enantiomeric pure (+)-lactones are only produced through whole-cell biotransformation of yeast.

A quinoline alkaloid rich floral extract enhances the bioactivity.

A volatile alkaloid quinoline-4-carbonitrile (QCN) was isolated from the floral extract of . Major compounds were -linalool oxide (1.0, 4.

Characterization of a class III peroxidase from Artemisia annua: relevance to artemisinin metabolism and beyond.

A class III peroxidase from Artemisia annua has been shown to indicate the possibility of cellular localization-based role diversity, which may have implications in artemisinin catabolism as well as lignification. Artemisia annua derives its importance from the antimalarial artemisinin. The -O-O- linkage in artemisinin makes peroxidases relevant to its metabolism.

Physicochemical analysis of Psophocarpus tetragonolobus (L.) DC seeds with fatty acids and total lipids compositions.

Psophocarpus tetragonolobus (L.) DC. is a tropical legume with potential nutritional properties.

Does the volatile hydrocarbon profile differ between the sexes: a case study on five aphidophagous ladybirds.

Insect hydrocarbons (HCs) primarily serve as a waterproofing cuticular layer and function extensively in chemical communication by facilitating species, sex, and colony recognition. In this study, headspace solid-phase microextraction is employed for investigating the sex-specific volatile HC profile of five ladybirds collected from Lucknow, India namely, Coccinella septempunctata (L.), Coccinella transversalis (Fabr.

Liquid CO2 extraction of Jasminum grandiflorum and comparison with conventional processes.

The concrete (0.35%) of Jasminum grandiflorum L. flowers was prepared by extraction in n-pentane, and the absolute (0.

Supercritical carbon dioxide extraction of wheat distiller's dried grain with solubles.

A wide variety of carbohydrates and starch-containing materials have been used for production of ethanol by the fermentation process. The alcohol from grain such as corn, wheat, barley, and sweet sorgum produced dried distillate grain with solubles (DDGS) and carbon dioxide as by-products. An attempt has been made to extract fatty oil from wheat DDGS using supercritical carbon dioxide (SC-CO₂).

Supercritical CO2 fractionation of bio-oil produced from wheat-hemlock biomass.

The biomass i.e. wheat-hemlock used in this study was first characterized for its composition.
