“…Besides the catalytic domain of cellulases, other accessory domains such as carbohydrate-binding modules (CBMs) may also exist [ 20 ]. The role of a CBM in increasing the enzyme concentration on the polysaccharide surface [ 21 ], facilitating cellotetrose dissociation, [ 22 ], decreasing the biomass crystallinity index and increasing the yield of hydrolytic products [ 23 ], have been proposed [ 24 ].…”

BackgroundThe high crystallinity of cellulosic biomass myofibrils as well as the complexity of their intermolecular structure is a significant impediment for biofuel production. Cloning of celB-, celC-encoded cellulases (cel12B and cel8C) and peh-encoded polygalacturonase (peh28) from Pectobacterium carotovorum subsp. carotovorum (Pcc) was carried out in our previous study using Escherichia coli as a host vector. The current study partially characterizes the enzymes’ molecular structures as well as their catalytic performance on different substrates which can be used to improve their potential for lignocellulosic biomass conversion.Resultsβ-Jelly roll topology, (α/α)6 antiparallel helices and right-handed β-helices were the folds identified for cel12B, cel8C, and peh28, respectively, in their corresponding protein model structures. Purifications of 17.4-, 6.2-, and 6.0-fold, compared to crude extract, were achieved for cel12B and cel8C, and peh28, respectively, using specific membrane ultrafiltrations and size-exclusion chromatography. Avicel and carboxymethyl cellulose (CMC) were substrates for cel12B, whereas for cel8C catalytic activity was only shown on CMC. The enzymes displayed significant synergy on CMC but not on Avicel when tested for 3 h at 45 °C. No observed β-glucosidase activities were identified for cel8C and cel12B when tested on p-nitrophenyl-β-d-glucopyranoside. Activity stimulation of 130% was observed when a recombinant β-glucosidase from Pcc was added to cel8C and cel12B as tested for 3 h at 45 °C. Optimum temperature and pH of 45 °C and 5.4, respectively, were identified for all three enzymes using various substrates. Catalytic efficiencies (k cat/K m) were calculated for cel12B and cel8C on CMC as 0.141 and 2.45 ml/mg/s respectively, at 45 °C and pH 5.0 and for peh28 on polygalacturonic acid as 4.87 ml/mg/s, at 40 °C and pH 5.0. Glucose and cellobiose were the end-products identified for cel8C, cel12B, and β-glucosidase acting together on Avicel or CMC, while galacturonic acid and other minor co-products were identified for peh28 action on pectin.ConclusionsThis study provides some insight into which parameters should be optimized when application of cel8C, cel12B, and peh28 to biomass conversion is the goal.

“…While there has been at least one other recent literature review on the subject of waste prevention [17] this research provides a broader view of the individual recycler, whereas Wilson et al have concentrated more on business attitudes and behaviors. There has also been a literature review on the determinants of recycling behavior [18] carried out 20 years ago.…”

Globally, waste volumes are increasing rapidly and the World Bank estimates a 70% global increase in municipal solid waste up to 2025. Waste may have serious environmental consequences and there is a strong correlation between solid waste generation rates and greenhouse gas emissions. These two observations alone indicate that this development is not sustainable. Recycling is one of the most important actions currently available to reduce the environmental impact of waste. While, waste recycling in OECD countries is reported to be approximately 22% on average, many developing countries have recycling rates in the range of 1-3%. A key aspect in succeeding with any recycling effort is how authorities and other actors relate to both informal and formal waste workers. This paper reports on the findings of a systematic literature study with the aim of exploring waste recycling behavior, with a special focus on motivational factors, both physical and psychological, behind recycling. Three levels of descending importance for recycling have been identified, where two are vital for success, and the third is desirable; 1) a well-designed infrastructure for recycling 2) specific recycling knowledge, and, 3) a general understanding of environmental aspects. Any attempt to implement or improve recycling systems and/or recycling behavior, needs to consider these aspects and the insights gained through this research may provide decision makers with practical assistance. The paper also contributes by providing academia with a framework for further studies on the behavioral aspects of recycling.

“…Limbah hasil industri menjadi salah satu persoalan serius di era industrialisasi. Oleh karena itu, regulasi tentang industrialisasi ramah lingkungan menjadi isu penting (Basaran, 2013;Wilson, et al, 2012). Alasan yang mendasari sebab limbah tidak hanya dari proses produksi tapi juga kelangsungan hidup.…”

Industrial Waste Management is one of the serious problems in the era of industrialization. Therefore waste management must be handled early during the production process. This means that the waste treatment process must be carried out from upstream to downstream. This study aims to build a waste management optimization model with quantitative analysis conducted through focus group discussions and in-depth interviews that combine the results of producer and consumer interviews. The results showed that there are many aspects related to waste from the tofu industry in the Abian Body Village, so it made waste optimization very important.
