This study was therefore carried out with the objective of estimating the biogas production potential of typical Vietnamese biomasses such as animal manure, slaughterhouse waste and plant residues, and developing a model that relates methane (CH4) production to the chemical characteristics of the biomass. The biochemical methane potential (BMP) and biomass characteristics were measured. Results showed that piglet manure produced the highest CH4 yield of 443 normal litter (NL) CH4 kg(-1)

volatile solids (VS) compared to 222 from cows, 177 from sows, 172 from rabbits, 169 from goats and 153 from buffaloes. Methane production from duckweed www.selleckchem.com/products/hmpl-504-azd6094-volitinib.html (Spirodela polyrrhiza) was higher than from lawn grass and water spinach at 340, 220, and 110.6 NL CH4 kg(-1) VS, respectively. The BMP experiment also demonstrated that the CH4 production was inhibited with chicken manure, slaughterhouse www.selleckchem.com/products/blz945.html waste, cassava residue

and shoe-making waste. Statistical analysis showed that lipid and lignin are the most significant predictors of BMP. The model was developed from knowledge that the BMP was related to biomass content of lipid, lignin and protein from manure and plant residues as a percentage of VS with coefficient of determination (R-square) at 0.95.This model was applied to calculate the CH4 yield for a household with 17 fattening pigs in the highlands and lowlands of northern Vietnam.”
“The tolerance to organophosphate pesticide, dichlorvos, is essential for the application of Trichoderma in bioremediation and integrated

pest management, although the molecular events associated with the tolerance process have not yet been elucidated. RNA-seq analysis of wild-type Trichoderma atroviride T23 and the hex1-deleted mutant under dichlorvos stress was designed to search for genes involved in the tolerance process. A total of 5382 differentially expressed genes were identified, highlighting the complex transcriptional changes of T. atroviride in response to dichlorvos stress. 137 genes were regulated by dichlorvos and hex1, encoding major facilitator superfamilies, cytochrome P450, glutathione-S-transferase, flavoprotein, JNK-IN-8 concentration Hsp70, Hsp90, etc. Pathway and expression analysis indicated that ABC transporters were affected by the disruption of hex1 gene and might play a vital role in the tolerance process. Expression patterns of seven selected ABC transporter genes were confirmed by qRT-PCR after exposure to dichlorvos for 2, 6 and 24 h. The present study provides insights into the genetic basis of dichlorvos tolerance in Trichoderma that may be exploited for further development of bioremediation or biocontrol agents.”
“Objective Systemic sclerosis (SSc) is characterized by fibrosis of the skin and visceral organs, vascular dysfunction, and immunologic dysregulation. Platelet-derived growth factors (PDGFs) have been implicated in the development of fibrosis and dysregulation of vascular function.
