Consolidated bio-saccharification (CBS) technology employs cellulosome-producing bacterial cells, rather than fungal cellulases, as biocatalysts for cost-effective production of lignocellulosic sugars. Extracellular β-glucosidase (BGL) expression in the whole-cell arsenal is indispensable, due to severe cellobiose inhibition of the cellulosome. However, high-level BGL expression in Clostridium thermocellum is challenging, and the optimal BGL production level for efficient cellulose saccharification is currently unknown. Herein, we obtained new CBS biocatalysts by transforming BGL-expressing plasmids into C. thermocellum, which produced abundant BGL proteins and hydrolyzed cellulose effectively. The optimal ratio of extracellular BGL-to-cellulosome activity was determined to be in a range of 5.5 to 21.6. Despite the critical impact of BGL, both excessive BGL expression and its assembly on the cellulosome via type I cohesin-dockerin interaction led to reduced cellulosomal activity, which further confirmed the importance of coordinated BGL expression with the cellulosome. This study will further promote industrial CBS application in lignocellulose conversion.p-coumaric acid (p-CA) can be produced from D-glucose by an engineered S. cerevisiae strain. p-CA has antimicrobial properties and retro-inhibition activity. Moreover, p-CA is a hydrophobic compound, limiting its accumulation in fermentation broth. To overcome these issues all at once, a liquid-liquid extraction in-situ product recovery process using oleyl alcohol as extractant has been implemented in order to continuously extract p-CA from the broth. Media and pH impacts on strain metabolism were assessed, highlighting p-CA decarboxylase endogenous activity. FI-6934 purchase Biphasic fermentations allowed an increase in p-CA respiratory production rates at both pH assessed (13.65 and 9.45 mg L-1.h-1 at pH 6 and 4.5, respectively) compared to control ones (10.5 and 7.5 mg L-1.h-1 at pH 6 and 4.5, respectively). Biphasic fermentation effects on p-CA decarboxylation were studied showing that continuous removal of p-CA decreased its decarboxylation into 4-vinylphenol at pH 4.5 (57 mg L-1 in biphasic fermentation vs 173 mg L-1 in control one).Food labelling is a tool to inform consumers about the specifications and characteristics of a product. Additionally, labels display information about traditionality and naturalness, of which the meaning is highly subjective. There is a paucity of research examining attributes both of tradition and naturalness. In this study, traditionality was assessed by a model that included temporal, geographical, know-how, and cultural components. Naturalness was evaluated based on bio/organic elements, 'free-from' claims, and natural ingredients. Therefore, a content analysis tool was developed to analyze and score labels of fermented meat products, which generated insights in the key label characteristics of tradition and naturalness. The degree of tradition and naturalness was the average of their subdimensions which were scored based on the displayed elements. A higher degree of tradition and naturalness was linked to higher prices. Fermented meat labels were found to be strongly embedded in 'authenticity', and less in naturalness, an element more attractive for private labels than for branded products.This paper summarises the contents of this Special Edition. The papers cover a range of advanced technologies for the objective measurement of carcass characteristics that influence the yield and potential eating quality of beef and lamb carcasses. All the research has been carried out in Australia and New Zealand and has been centrally funded with collaboration between various groups. This Special Edition is timely since the meat industry is coming under pressure on environmental grounds in addition to health warnings about excessive meat consumption. In this respect it is encouraging that so many of the papers relate to eating quality. The emphasis on objective methods is also important as moving away from traditional subjective grading will improve accuracy and consistency and thereby increase efficiency. Some differences in the approach taken in other parts of the world are discussed.
Intolerance of uncertainty (IU) is an individual difference factor that reflects difficulty tolerating emotional distress in the context of uncertainty and is a robust transdiagnostic risk factor for emotional disorders. A limitation of prior research on IU is the heavy reliance on self-report measures to assess this construct. The aim of the present study was to examine the validity of a brief, computerized anagram task modified to assess IU (the PACT Anagram Task; PAT).
Participants were 221 unselected undergraduate students (71% female; M
=19; 89% Caucasian) who completed the PAT and a series of self-report measures of convergent, discriminant, and incremental validity, and measures of anxiety and depression symptoms online for course credit.
Greater PAT-Distress was positively correlated measures of convergent validity and demonstrated incremental validity in relation to self-reported IU above and beyond attentional control. None of the PAT indicators were associated with compassion or empathic concern, evidencing discriminant validity. PAT-Distress and PAT-Answers were each associated with greater worry above and beyond self-reported IU.
Study limitations include the cross-sectional design and lack of diversity in terms of sample demographics. Furthermore, we did not examine convergence between this task and other behavioral measures of IU.
Subjective distress following completion of the PAT may serve as one indicator of IU. Further research is needed in order to replicate these results and validate the use of the PAT in clinical samples.

However, most previous studies have mainly focused on health-related economic losses, while the negative effects of haze pollution on the tourism industry are often ignored, leading to the unsustainable development of tourism. In this context, contrasting with previous research perspectives, this article selected several representative tourist cities from East China, South China, Central China, North China, Northwest China, Southwest China, and Northeast China as research objects in an empirical study, developing an economic loss analysis system to quantitatively evaluate the losses in the tourism industry caused by haze pollution. This system uses the satin bower bird optimization-based distribution estimation method to identify the optimal distribution of haze pollution, demonstrating superior performance to the traditional estimation method. Meanwhile, the optimal distribution of haze pollution is employed to measure the probability of different concentration limits in each area.
