Anaerobic digestion is a naturally occurring biological process in which large numbers of anaerobic bacteria convert organic matter into methane and carbon dioxide (a mixture called biogas) in the absence of air. It is a widely used biological process for treating wastewater solids. This process stabilizes the organic matter in wastewater solids, reduces pathogens and odors, and reduces the tot...

The 1990 Clean Air Act Amendments prompted an increased urgency to find new ways to treat airstreams containing volatile organic compounds, which affect the nitrogen photolytic cycle and help produce ground-level ozone, hazardous air pollutants, and odorous air emissions such as hydrogen sulfide. Scientists at the New Jersey company Envirogen have adapted traditional biofiltration technology to...

Differences in volatile terpene content of Pinus caribaea needles and soil qualities between two pine plantations (Uverito and Sartenejas) in Venezuela were analyzed. Soils in the Uverito pine plantation were sandy, low in nutritional quality, and deficient in available nitrogen and phosphorus content. Pines grown on these soils presented in their needles higher concentrations of alpha-pinene, ...

Four ruminally cannulated Holstein cows were used in a 4 × 4 Latin square design to determine the effect of feeding linted, delinted and extruded linted whole cottonseed (WCS) on nutrient digestibility and ruminal fermentation. Result showed that crude protein digestibility was lower in linted and delinted WCS treatments than control and extruded linted WCS treatment. Cows fed extruded delinted...

This study was conducted to determine the shelf life and quality of traditional canned fish made from bonito (Sarda sarda) fish. The effect rosemary plant on some parameters storage time with tomato sauce stored for 510 days at room temperature determined by sensory, physical, chemical microbiological freshness control methods. Nutrient composition analyses were performed in before canning proc...

Abstract Lactolisterin BU is a novel bacteriocin identified from Lactococcus lactis in 2017. It exhibits antimicrobial activity against food spoilage and foodborne pathogens. In this study, was expressed Pichia pastoris ( P.pastoris ) isolated the supernatant of yeast culture for first time. found to exhibit broad spectrum rapid bactericidal bacterial pathogens, both gram-positive gram-negative...

This study is focused on the effect of phycobiliprotein extraction Gracilaria quality common carp burgers, and application nanoliposomes containing pigment in improvement its antimicrobial antioxidant activity burgers during refrigerated storage 18 days. Burgers were incorporated with liposomal (2.5% 5% w/w), their chemical microbial changes terms pH, peroxide value (PV), thiobarbituric acid (T...

AIMS The aim of the study was to assess the relationships between the remaining shelf-life (RSL) of cold-smoked salmon and various microbiological and physico-chemical parameters, using a multivariate data analysis in the form of stepwise forward multiple regression. METHODS AND RESULTS Thirteen batches of French cold-smoked salmon were analysed weekly during vacuum-packed storage at 5 degree...

One quorum sensing strain was isolated from spoiled turbot. The species was determined by 16S rRNA gene analysis and classical tests, named Aeromonas sobria AS7. Quorum-sensing (QS) signals (N-acyl homoserine lactones (AHLs)) were detected by report strains and their structures were further determined by GC-MS. The activity changes of AHLs on strain growth stage as well as the influence of diff...
