    碳水化合物是在饮食中提供能量的三种常量营养素之一,并按其结构进行分类。淀粉是由葡萄糖单体制成的非结构性碳水化合物和多糖,用于在植物细胞中储存。当淀粉占饮食中DM的30%以上时,由于瘤胃pH的降低,可能对NDF消化率产生不利影响。糖是由单糖和二糖单元组成的水溶性碳水化合物。糖比淀粉发酵更快,因为瘤胃中的微生物可以根据碳水化合物的结构以不同的速率发酵碳水化合物;然而,这没有显示对瘤胃pH有负面影响。糖的来源如糖蜜(蔗糖)或乳清(乳糖)可以包括在饮食中作为乳牛饮食中淀粉的部分替代品。用饮食中的糖代替淀粉的目的是在饮食中添加不同来源的碳水化合物,以允许瘤胃中的微生物对碳水化合物进行连续发酵。在研究和先前的文献中已经看到,用糖部分替代淀粉具有维持奶牛的瘤胃环境和乳产量和组成而不降低NDF消化率的潜力。这篇综述的目的是评估乳制品日粮中部分用糖代替淀粉的影响及其对瘤胃发酵的影响。养分利用率,牛奶生产,和喂养替代策略。
    Carbohydrates are one of the three macronutrients that provides energy in diets and are classified by their structures. Starch is a nonstructural carbohydrate and polysaccharide made of glucose monomers used for storage in plant cells. When starch makes up greater than 30% of the DM in diets there can be adverse effects on NDF digestibility due to decreases in ruminal pH. Sugars are water soluble carbohydrates that consist of monosaccharide and disaccharide units. Sugars ferment faster than starch because microorganisms in the rumen can ferment carbohydrates at different rates depending on their structure; however, this has not been shown to have negative effects on the ruminal pH. Sources of sugars such as molasses (sucrose) or whey (lactose) can be included in the diet as a partial replacement for starch in dairy cow diets. The purpose of replacing starch with sugars in a diet would be to add differing sources of carbohydrates in the diet to allow for continual fermentation of carbohydrates by the microorganisms in the rumen. It has been seen in studies and previous literature that the partial replacement of starch with sugars has the potential to maintain the ruminal environment and milk yield and composition in dairy cows without reducing NDF digestibility. The objective of this review is to evaluate the effects of partially replacing starch with sugars in dairy diets and its implication on ruminal fermentation, nutrient utilization, milk production, and feeding replacement strategy.

    乌头酸(丙烯-1,2,3-三羧酸)是在甘蔗和甜高粱中积累的最普遍的6-碳有机酸。作为一种顶级增值化学品,乌头酸可以作为化学前体或中间体用于高价值的下游工业和生物应用。这些下游应用包括用作生物基增塑剂,交联剂,以及形成有价值的多功能聚酯,这些聚酯也已用于组织工程。乌头酸在细胞内作为三羧酸循环的中间物和作为拒食剂赋予某些植物独特的生存优势也发挥各种生物学作用。抗真菌药,以及储存固定碳库的方法。乌头酸也被报道为发酵抑制剂,抗炎,和潜在的杀线虫剂.由于乌头酸可以从可再生的可持续来源,廉价的来源,如甘蔗,糖蜜,和甜高粱糖浆,通过下游工业和生物应用,我们在这篇综述中讨论,有巨大的潜力为制糖业提供多种额外收入。
    Aconitic acid (propene-1,2,3-tricarboxylic acid) is the most prevalent 6-carbon organic acid that accumulates in sugarcane and sweet sorghum. As a top value-added chemical, aconitic acid may function as a chemical precursor or intermediate for high-value downstream industrial and biological applications. These downstream applications include use as a bio-based plasticizer, cross-linker, and the formation of valuable and multi-functional polyesters that have also been used in tissue engineering. Aconitic acid also plays various biological roles within cells as an intermediate in the tricarboxylic acid cycle and in conferring unique survival advantages to some plants as an antifeedant, antifungal, and means of storing fixed pools of carbon. Aconitic acid has also been reported as a fermentation inhibitor, anti-inflammatory, and a potential nematicide. Since aconitic acid can be sustainably sourced from renewable, inexpensive sources such as sugarcane, molasses, and sweet sorghum syrup, there is enormous potential to provide multiple streams of additional income to the sugar industry through downstream industrial and biological applications that we discuss in this review.

    : Background: Constipation in hospitalized patients is common. As a treatment of last resort for unresolved constipation, a milk and molasses enema is often used by nursing staff. But there has been little research investigating the safety and efficacy of this approach.
    OBJECTIVE: The purpose of this retrospective study was to evaluate the safety of milk and molasses enemas for hospitalized adults with constipation that remained unresolved after standard treatment options were exhausted.
    METHODS: Data were extracted from the electronic health records (EHRs) of 615 adult patients who had received a milk and molasses enema between July 2009 and July 2013 at a large midwestern academic medical center. Data analysis occurred for a random subset of this group.Participant characteristic variables included age, sex, admitting diagnosis, diet orders, medications, laxatives and enemas administered before the milk and molasses enema, and laboratory values. Serious complication variables included bacteremia, bowel perforation, electrolyte abnormalities, allergic reaction, abdominal compartment syndrome, cardiac arrhythmia, dehydration, and death.
    RESULTS: The final sample of 196 adults had a mean age of 56 years; 61.2% were female and 38.8% were male. Of 105 admitting diagnoses, the most frequent (9.7%) was abdominal pain, unspecified site. Of the 14 discharge dispositions, the most frequent was home or self-care (50.5%). A laxative order was present for 97.4% of patients and a stool softener order was present for 86.2%. Sodium and potassium levels remained within normal limits during hospitalization. For the subset of patients who had these values measured within 48 hours before and after milk and molasses enema administration, no significant changes were found. No cases of nontraumatic abdominal compartment syndrome or other serious adverse enema-related events were documented in the EHR.
    CONCLUSIONS: No safety concerns were identified from this retrospective EHR review of hospitalized adults who received a milk and molasses enema for constipation relief. The findings indicate that this treatment is safe, although further study examining its efficacy in this population is needed.

    Distillery effluent is a contaminated stream with high chemical oxygen demand (COD) varying from 45,000 to 75,000 mg/l and low pH values of between 4.3 and 5.3. Different processes covering aerobic, anaerobic as well as physico-chemical methods which have been employed to this effluent has been given in this review paper. Among the different methods available, it was found that \"An Inverse Anaerobic Fluidization\" to be a better choice for treating effluent from molasses-based distillery industries using an inverse anaerobic fluidized-bed reactor (IAFBR). This technology has been widely applied as an effective step in removing 80-85% of the COD in the effluent stream. Therefore, in this review, attention has been paid to highlight in respect of fluidization phenomena, process performance, stability of the system, operating parameters, configuration of inverse anaerobic fluidization and suitable carrier material employed in an inverse anaerobic fluidized-bed reactor especially for treating this effluent.

    Molasses-based distilleries are one of the most polluting industries generating large volumes of high strength wastewater. Different processes covering anaerobic, aerobic as well as physico-chemical methods have been employed to treat this effluent. Anaerobic treatment is the most attractive primary treatment due to over 80% BOD removal combined with energy recovery in the form of biogas. Further treatment to reduce residual organic load and color includes various: (i) biological methods employing different fungi, bacteria and algae, and (ii) physico-chemical methods such as adsorption, coagulation/precipitation, oxidation and membrane filtration. This work presents a review of the existing status and advances in biological and physico-chemical methods applied to the treatment of molasses-based distillery wastewater. Both laboratory and pilot/industrial studies have been considered. Furthermore, limitations in the existing processes have been summarized and potential areas for further investigations have been discussed.

    Effluent originating from distilleries known as spent wash leads to extensive soil and water pollution. Elimination of pollutants and colour from distillery effluent is becoming increasingly important from environmental and aesthetic point of view. Stillage, fermenter and condenser cooling water and fermenter wastewater are the primary polluting streams of a typical distillery. Due to the large volumes of effluent and presence of certain recalcitrant compounds, the treatment of this stream is rather challenging by conventional methods. Therefore, to supplement the existing treatments, a number of studies encompassing physico-chemical and biological treatments have been conducted. This review presents an account of the problem and the description of colour causing components in distillery wastewater and a detailed review of existing biological approaches. Further, the studies dealing with pure cultures such as bacterial, fungal, algal and plant based systems have also been incorporated. Also, the roles of microbial enzymes in the decolourization process have been discussed to develop a better understanding of the phenomenon.
