Orange peel valorization by pyrolysis under the carbon dioxide environment.

To valorize biomass waste, pyrolysis of orange peel was mainly investigated as a case study. In an effort to establish a more sustainable thermolytic platform for orange peel, this study particularly employed CO as reactive gas medium. Accordingly, this study laid great emphasis on elucidating the mechanistic role of CO in pyrolysis of orange peel. The thermo-gravimetric analysis (TGA) confirmed that no occurrence of the heterogeneous reactions between the solid sample and CO. However, the gaseous effluents...

Orange and Passion Fruit Wastes Characterization, Substrate Hydrolysis and Cell Growth of Cupriavidus necator, as Proposal to Converting of Residues in High Value Added Product.

Brazil is the world's largest producer of orange and passion fruit, which are destined mainly for industrialization, generating grand volumes of wastes. The solid portion of these residues is a rich source of pectin - composed mainly of galacturonic acid and neutral sugars, which through the hydrolysis process can be used in biological conversion processes, as the production of polyhydroxyalkanoates (PHAs). This way, we characterized these wastes, followed by the extraction and hydrolysis of pectin for empl...


Pulp in Shop-Bought Orange Juice Has Little Effect on Flavonoid Content and Gut Bacterial Flavanone Degradation In Vitro.

Orange juice is an important source of flavanones in the Western diet. However, little is known of the variation in flavanone content of shop-bought orange juice with pulp (OJP) or without pulp (OJ), nor the impact of pulp on the fate of flavanones in the gut. Total phenols, total flavonoids, antioxidant capacity, hesperidin and narirutin, and dietary fibre were measured in six orange juice brands sold as OJP and OJ. The inclusion of pulp had little impact on fibre content. Apart from total phenols (OJ: 208...

Biochemical and Molecular Factors Governing Peel-Color Development in 'Ora' and 'Shani' Mandarins.

To identify factors governing peel-color development in mandarins, we examined carotenoid content and composition and the expression of carotenoid-related genes during four stages of ripening (i.e., green, breaker, yellow and orange) in two varieties: 'Ora', which has orange fruit, and 'Shani', which has orange-reddish fruit. The two varieties had different carotenoid compositions and 'Shani' had a significantly higher level of total carotenoid pigments. 'Shani' was rich in the deep orange β-cryptoxanthin ...

Recognition of the neutral sugars conversion induced by bacterial community during lignocellulose wastes composting.

The aim of this study was to explore the conversion characteristics of neutral sugars during different lignocellulose wastes composting from rice straw (RS), leaf (L) and mushroom dreg (MD). The results showed that the changes of neutral sugars were different during different wastes composting, but the changes of various hexose or pentose were similar during composting of the same material. The diversity of bacterial community led to different conversion characteristics of neutral sugars. During RS composti...

Cu(II)-enhanced degradation of acid orange 7 by Fe(II)-activated persulfate with hydroxylamine over a wide pH range.

The activation of persulfate by Fe(II) coupled with hydroxylamine (the HA/Fe(II)/PS system) was highly effective for the degradation of refractory organic contaminants under acidic pH conditions. However, owing to the precipitation of ferric hydroxide and/or the slow reduction from Fe(III) to Fe(II), the HA/Fe(II)/PS system was invalid under neutral and alkaline pH conditions. In this study, it was observed that the degradation of acid orange 7 (AO7) was strongly enhanced over the wide pH range of 2-9 when ...

Serum dioxin and DNA methylation in the sperm of operation ranch hand veterans exposed to Agent Orange.

Exposure to the herbicide Agent Orange during the Vietnam War was widespread and is associated with numerous adverse health outcomes. A continuing concern of veterans is the possibility that exposure to the dioxin-containing herbicide might induce adverse reproductive outcomes. We sought to assess whether exposure to Agent Orange in Vietnam was associated with changes in DNA methylation in sperm in a subset of Vietnam veterans who participated in the Air Force Health Study (AFHS).

Participants free of CVD and cancer and aged ≥40 y at baseline ( = 6,491) from the Third National Health and Nutrition...

A crosslinking strategy to make neutral polysaccharide nanofibers robust and biocompatible: With konjac glucomannan as an example.

Neutral polysaccharides such as konjac glucomannan, starch and pullulan are abundant in nature and have unique property. Their nanofibers hold great potential for biomedicine, which however, are seldom applied in the field due to the lack of crosslinking method. In this work, we report a periodate oxidation - adipic acid dihydrazide (ADH) crosslinking strategy to prepare robust and biocompatible neutral polysaccharide nanofibers. Neutral polysaccharides with adjacent dihydroxyl groups are firstly partially ...

Morphological and Histochemical Description of Quail Feather Development.

The current study investigated the macroscopic and microscopic differences between pennaceous and plumulaceous feathers. The morphology of the barbules distinguished pennaceous and plumulaceous feathers, particularly the shape of barbules during their development. In pennaceous feathers, the initial barbules were large and elongated or pyriform in shape, while plumulaceous feathers had small, thin, elongated initial barbules. The spinous barbules were characteristic of pennaceous feathers. The histochemical...

Reaction between NH3 (X ̌ 1A1) and CO (X 1Ʃ+): A Computational Insight into the Reaction Mechanism of Formamide (H2N-CHO) Formation.

Formamide (NH2CHO) is the smallest molecular unit, which contains the basic peptide linkage and thus has recently attracted great amount of interest in the field of astrochemistry. In this work using computational calculations, we have analysed the three possible reaction paths for the reaction between CO and NH3 to form formamide in both neutral-neutral and cation-neutral reaction surfaces. All these three paths strongly favours the path of 1,2-hydrogen migration, which was discounted by previous studies i...

We have carried out an extensive quantum chemical exploration of gas-phase Alkali Metal Cation Affinities (AMCA) of archetypal neutral bases across the periodic system using relativistic density functional theory. One objective of this work is to provide an intrinsically consistent set of values of the 298K AMCAs of all neutral maingroup-element hydrides XHn of groups 15-18 along the periods 1-6. Our main purpose is to understand these trends in terms of the underlying bonding mechanism using Kohn-Sham mole...

Use of free and encapsulated nerolidol to inhibit the survival of Lactobacillus fermentum in fresh orange juice.

Lactobacillus fermentum is commonly responsible for fruit juice fermentation and spoilage. The aim of this study was to investigate the potential use of nerolidol to control the spoilage of fresh orange juice by L. fermentum. Nerolidol was incorporated into hydroxypropyl-β-cyclodextrin inclusion complex, conventional liposome, and drug-in-cyclodextrin-in liposome systems. The systems were lyophilized and characterized with respect to their nerolidol content, size, and morphology. The effects of the acidity...

The influence of context condition on outcome evaluation in experimental conditions: Even vs. neutral.

Feedback-related negativity (FRN) is an event-related brain potential that is elicited during outcome evaluation. Studies have found that FRN reflects a good vs. bad classification; more importantly, FRN reflects this classification in a context-dependent manner, which means that the outcome evaluation is obviously influenced by its embedded context. In the current study, we examined how the context conditions of even (i.e., the feedback was +4 or -4) and neutral (i.e., the feedback was always 0) affect the...

Retrotransposon promoter of Ruby1 controls both light- and cold-induced accumulation of anthocyanins in blood orange.

Blood orange is generally recognized to accumulate anthocyanins in its fruit pulp in a cold-inducible manner. We observed that the fruit peel of blood orange can also accumulate anthocyanins under ample light conditions. Interestingly, purple pummelo can accumulate anthocyanins only in its fruit peel but not in its pulp. The mechanism underlying the tissue specificity of anthocyanin accumulation in citrus is unknown. Here, we show that the active promoter of Ruby1, a key activator of anthocyanin biosynthesi...

Associations between fecal bile acids, neutral sterols, and serum lipids in the KORA FF4 study.

Dyslipidemia is a major risk factor for cardiovascular disease, the leading cause of preventable death worldwide. As a result, a full understanding of the factors influencing dyslipidemia is urgently necessary. Bile acids have been recognized as regulators of lipid metabolism, and neutral sterols may influence serum lipid levels. Therefore, this analysis was conducted to better understand the relationship between bile acids, neutral sterols, and dyslipidemia.

Impaired neural habituation to neutral faces in families genetically enriched for social anxiety disorder.

Social anxiety disorder (SAD) is an incapacitating disorder running in families. Previous work associated social fearfulness with a failure to habituate, but the habituation response to neutral faces has, as of yet, not been investigated in patients with SAD and their family members concurrently. Here, we examined whether impaired habituation to neutral faces is a putative neurobiological endophenotype of SAD by using data from the multiplex and multigenerational Leiden Family Lab study on SAD.
