INDUSTRIAL APPLICATIONS OF WILD AND GENETICALLY-MODIFIED STRAINS OF ACETIC ACID BACTERIA

Acetic Acid Bacteria (AAB) have been known for many years, since humans first used them to produce vinegar. AAB serve as biocatalysts in industrial production of, inter alia, acetic acid, dihydroxyacetone, gluconic acid, bacterial cellulose or levan. Apart from the traditional industrial applications of wild strains of AAB, scientists strive to develop novel methods for the production of selected compounds using genetically-modified AAB. The application of such mutants in the industry entails

Acetic Acid, 2-Undecanone, and (E)-2-Decenal Ultrastructural Malformations on Meloidogyne incognita

metabolites, that is acetic acid, (E )-2-decenal, and 2-undecanone. The commercial nematicide fosthiazate acting on acetylcholinesterase was used as control.For this reason, scanning electron microscopy and transmission electron microscopy have been employed. The acetic acid mainly harmed the cuticle, degenerated the nuclei of pseudocoel cells, and vacuolised the cytoplasm. The (E)-2-decenal and 2-undecanone did neither harm to the cuticle nor the somatic muscles but they degenerated the

Inhibition of neuronal and inducible nitric oxide synthase does not affect the analgesic effects of NMDA antagonists in visceral inflammatory pain

antinociceptive action of magnesium sulfate and dizocilpine. Analgesic activity was assessed using the acetic acid-induced writhing test in rats. Subcutaneous injection of either magnesium sulfate (15 mg/kg) or dizocilpine (0.01 mg/kg) decreased the number of writhes by about 60 and 70%, respectively. The role of nitric oxide on the effects of magnesium sulfate and dizocilpine was evaluated using selective inhibitor of neuronal [N-ω-Propyl-L-arginine hydrochloride (L-NPA)] and inducible [S-methylisothiourea

Direct Fermentative Hydrogen Production from Cellulose and Starch with Mesophilic Bacterial Consortia

average HPR reached 26 ml H2/l-h. This time hydrogen was not subsequently consumed, as it was observed when the inoculum was pretreated at 90°C, but its volume was stabilized. A similar volume of hydrogen was produced also in the next cycle. In contrast, Wang et al. (2011) observed that increasing the temperature of inoculum pretreatment from 80°C to 100°C resulted in decreased H2 yields from glucose. In this study, the main metabolites were butyric and acetic acid (Fig. 2). Formic acid was also

Isolation and Characterization of Phosphate-Solubilizing Bacteria from Mushroom Residues and their Effect on Tomato Plant Growth Promotion

produced indole acetic acid (61.5%), and six isolates produced siderophores (46.2%). Three highest phosphate-dissolving bacterial isolates, namely, M01, M04, and M11, were evalu­ated for their beneficial effects on the early growth of tomato plants (Solanum lycopersicum L. Wanza 15). Strains M01, M04, and M11 significantly increased the shoot dry weight by 30.5%, 32.6%, and 26.2%, and root dry weight by 27.1%, 33.1%, and 25.6%, respectively. Based on 16S rRNA gene sequence comparisons and

Prevalence and Antimicrobial Properties of Lactic Acid Bacteria in Nigerian Women During the Menstrual Cycle

that will report the presence of these two species in the vagina of a woman. B. safensis has biotechnological and industrial potentials (Larboda et al. 2014) while A. pasteurianus is important in vinegar production (Viana et al. 2017). The mechanism by which this organism inhibits the three uropathogens used in this study is probably due to the production of acetic acid. The resistance of S. aureus strain to the cell-free supernatant from most of the LAB strains in this study prompted another

The Joint Effect of pH Gradient and Glucose Feeding on the Growth Kinetics of Lactococcus lactis CECT 539 in Glucose-Limited Fed-Batch Cultures

biomass, nisin, lactic acid, acetic acid and butane-2,3-diol by L. lactis strains. For these reasons, in the present study, a first glucose-limited realkalized fed-batch culture in DW medium was designed by using a medium prepared with mussel processing wastes (CMPW) and a 400 g/l concentrated lactose (CL) as feeding media. From the results obtained in this culture, the effects of glucose addition and VpH on biomass and product synthesis by L. lactis CECT 539 were quantified, for the first time, by
