Project description:Coffee leaf miner is an important plague in coffee crops. Using subtracted cDNA libraries and nylon filter arrays, we analyzed the expression profile of 1536 expressed sequence tags (ESTs) of coffee plants from an hybrid progeny (C. arabica x C. racemosa), containg resistant (R) and susceptible plants (S) to the infestation of coffee leaf miner. Leaf discs were collected from non-infested plants (R control - RC; S control - SC), infested plants after moth oviposition (R oviposition - Ro; S oviposition - So) and infested after larvar eclosion (R eclosion - Re; S eclosion - Se).

Project description:Cellulose is the most abundant component of plant litter, which is critical for terrestrial carbon cycling. Nonetheless, it remains unknown how climate changes affect cellulose-decomposing microorganisms. Here, we carried out a multi-year litterbag experiment to examine cellulose decomposition undergoing +3°C warming in an Oklahoma tallgrass prairie, USA. GeoChip 5.0M was employed to detect microbial functional genes.

Project description:Coffee is one of the most important commodities cultivated worldwide and has great economic impact in producing countries. Although 130 different species belonging to the coffea gender have been described, only two of them are commercially exploited: Coffea arabica and Coffea canephora. C. arabica is responsible for 61% of the world production (Van der Vossen et al., 2015). However, due to the narrow genetic back ground, classical genetic breeding is time consuming and takes around 30 years (Santana-Buzzy et al., 2007; Hendre et al., 2014). Several genetic engineering and biotechnological tools have been successfully applied in coffee breeding. Somatic embryogenesis (SE) is a process in which new viable embryos are produced from somatic tissues. It is one of the most promising production processes (Santana-Buzzy et al, 2007; Marsoni et al., 2008). A better understanding of the molecular basis related to somatic embryogenesis will give insight into the process of embryo formation and totipotency and will allow the development of new in vitro culture strategies for the propagation and genetic manipulation of elite cultivars (Marsoni et al., 2008). High throughput proteomics in coffee is limited so far to 2D gel based proteomics techniques. Although really useful and the most common technique for plants, 2DE is limited in throughput and a gel free technique allow to go a step further (Carpentier & America, 2014; Vanhove et al., 2015). To improve the knowledge about somatic embryogenesis, we present the first high throughput proteome profile (1051 confident protein identifications) of coffee embryogenic cell suspensions developed from leaves of Coffea arabica cultivar Catuaí.

Project description:The present study was conducted to evaluate the effects of the intake of three types of coffee (caffeinated, decaffeinated, and green unroasted coffee) on the livers of C57BL/6J mice fed a high-fat diet, and to extensively elucidate the physiological responses to coffee intake by analysing the findings obtained from a comprehensive transcriptomic analysis using DNA microarrays.

Project description:Industrial development and increased energy requirements have led to high consumption of fossil fuels. Thus, environmental pollution has become a profound problem. Every year, a large amount of agro-industrial, municipal and forest residues are treated as waste, but they can be recovered and used to produce thermal and electrical energy through biological or thermochemical conversion processes. Among the main types of agro-industrial waste, soluble coffee residues represent a significant quantity all over the world. Silver skin and spent coffee grounds (SCG) are the main residues of the coffee industry. The many organic compounds contained in coffee residues suggest that their recovery and use could be very beneficial. Indeed, thanks to their composition, they can be used in the production of biodiesel, as a source of sugar, as a precursor for the creation of active carbon or as a sorbent for the removal of metals. After a careful evaluation of the possible uses of coffee grounds, the aim of this research was to show a broad characterization of coffee waste for energy purposes through physical and chemical analyses that highlight the most significant quality indexes, the interactions between them and the quantification of their importance. Results identify important tools for the qualification and quantification of the effects of coffee waste properties on energy production processes. They show that (SCG) are an excellent raw material as biomass, with excellent values in terms of calorific value and low ash content, allowing the production of 98% coffee pellets that are highly suitable for use in thermal conversion systems. Combustion tests were also carried out in an 80kWth boiler and the resulting emissions without any type of abatement filter were characterized.

Project description:In a world where an eco-friendlier approach is becoming more and more necessary, it is essential to reduce waste production and to reuse residues of the company's supply chain. Coffee silverskin (CS) and spent coffee ground (SCG), two by-products of coffee production, are important sources of bioactive compounds and, for this, some authors have proposed their reuse in the nutraceutical, food, and cosmetic sector. However, their potential enzyme inhibitory properties have been poorly investigated. Hence, the objective of the current work was to study the enzymatic inhibitory activities against acetylcholinesterase, butyrylcholinesterase, α-amylase, α-glucosidase, and tyrosinase of different extracts of CS and SCG. Before these in vitro bioassays, the phytochemical composition of each extract was investigated via colorimetric assays and HPLC-MS/MS analysis. In addition, the antioxidant activities were evaluated by different chemical approaches. SCG extracts contained a higher content of bioactive compounds, notably the SCG EtOH:H2O extract was the richest in caffeine and possessed the highest antioxidant activities. The hydroalcoholic and methanolic extracts were shown to be the most active against all tested enzymes, while the water extracts displayed lower activity. Our results showed a weak correlation between bioactive compounds and enzyme inhibitory effects, proving inhibitory activities likely due to non-phenolic molecules such as alkaloids and terpenoids. Obtained findings could be a starting point to develop novel nutraceuticals from CS and SCG.

Briefly, 7-week-old male C57BL/6J mice purchased from Charles River Laboratories Japan (Yokohama) were divided into the following five groups. The normal diet group (ND group) was fed D12450B (10 kcal% fat, Research Diets, New Brunswick, NJ, USA). The high-fat diet group (HF group) was fed D12492 (60 kcal% fat, Research Diets, New Brunswick, NJ, USA). The caffeinated coffee group (HFCC group) was fed a high-fat diet containing 2% caffeinated freeze-dried coffee. The decaffeinated coffee group (HFDC group) was fed a high-fat diet containing 2% decaffeinated freeze-dried coffee. The green unroasted coffee group (HFGC group) was fed a high-fat diet containing 2% unroasted caffeinated freeze-dried coffee. The mice had ad libitum access to their diets and drinking water. After 9 weeks, mice were sacrificed and the livers were subjected to the Affymrtix DNA microarray experiment.
