Several strains belonging to the genus Bifidobacterium were tested to determine their abilities to produce succinic acid. Bifidobacterium longum strain BB536 and Bifidobacterium animalis subsp. lactis strain Bb 12 were kinetically analyzed in detail using in vitro fermentations to obtain more insight into the metabolism and production of succinic acid by bifidobacteria. Changes in end product formation in strains of Bifidobacterium could be related to the specific rate of sugar consumption. When the specific sugar consumption rate increased, relatively more lactic acid and less acetic acid, formic acid, and ethanol were produced, and vice versa. All Bifidobacterium strains tested produced small amounts of succinic acid; the concentrations were not more than a few millimolar. Succinic acid production was found to be associated with growth and stopped when the energy source was depleted. The production of succinic acid contributed to regeneration of a small part of the NAD+, in addition to the regeneration through the production of lactic acid and ethanol.

The application of hydrogels to drug delivery limited by the difficulty of encapsulating hydrophobic drugs; therefore, the development of novel composite hydrogels for the delivery of hydrophobic drugs is urgently needed. In this study, terbinafine hydrochloride/hydroxypropyl-β-cyclodextrin inclusion complexes (TFH/HP-β-CD ICs) were added to a Schiff base hydrogel matrix containing octenyl succinic anhydride-modified chitosan (OSA-CS) and sodium alginate (OIA) to prepare a TFH composite hydrogel (TFH GEL). The results revealed that the solubility of TFH in water within TFH/HP-β-CD IC reached 32.

Soil contamination with toxic heavy metals [such as cadmium (Cd)] is becoming a serious global problem due to the rapid development of the social economy. Organic chelating agents such as succinic acid (SA) and oxalic acid (OA) are more efficient, environmentally friendly, and biodegradable compared to inorganic chelating agents and they enhance the solubility, absorption, and stability of metals. To investigate this, we conducted a pot experiment to assess the impact of SA (0.

Objective: A majority of small size kidney in children were diagnosed after a urinary tract infection (UTI) and with high-grade vesicoureteral reflux (VUR). This study was conducted in children who were diagnosed accidentally and investigated for VUR and UTI.
Methods: This longitudinal retrospective study was conducted in children with a diagnosis of a small kidney accidentally discovered by ultrasonography and referred to Children's Hospital in Babol, Iran, between 2012-2022.

The past decades have witnessed the increasing accumulation of plastics, posing a daunting environmental crisis. Among various solutions, converting plastics into value-added products presents a significant endeavor. Here, an electrocatalytic upcycling route that efficiently converts waste poly(butylene terephthalate) plastics into high-value succinic acid with high Faradaic efficiency of 94.
