There has been an explosion of research on host-associated microbial communities (i.e.,microbiomes). Much of this research has focused on surveys of microbial diversities across a variety of host species, including humans, with a view to understanding how these microbiomes are distributed across space and time, and how they correlate with host health, disease, phenotype, physiology and ecology....

Microbial growth onto HVAC filters was observed in real conditions with possible degradation of the indoor air quality. The filtration performance marketed antimicrobial containing zinc pyrithione tested under laboratory and compared to that similar same classification, F7 (EN779:2002). two during loading PM10 particles quantified an experimental setup filter pressure drop measurement particle ...

Introduction: Alpha-Momorcharin (α-MMC) is a member of the ribosome-inactivating protein (RIP) family that has been widely used as an antitumor, antiviral and antifungal agent. Methods: In this study, codons DNA encoding α-MMC were optimized for expression in E. coli cloned into pET-28a(+) vector. The was then expressed strain BL21 (DE3) purified by nickel affinity chromatography. Results: Unde...

Rice straw contains a large amount of lignocellulose which is difficult to be decomposed. The objective this study was determine the effect alkaline pretreatment (sodium hydroxide, NaOH) and microbial agents on decomposition rice straw. experimental detail consisted NaOH (control solution pretreatment) agent (Bacillus licheniformis agent, Bacillus subtilis Trichoderma viride no agent) treatment...

This study was aimed at developing a compound microbial agent to facilitate the composting of Chinese medicinal herbal residues (CMHRs). Different agents were inoculated into mixture CMHRs, sheep manure, and biochar composted for 42 days. The results demonstrated that (K1 + P1 N4) in T1 can extend thermophilic period during composting. Compared with control check (CK), total nutrient contents v...

in this paper, a formal model for antivirus update agent system is presented based on mobile agent technology and predicate/transition petri nets. the mobile agent system contains two mobile agents called dca and una. it sends out agents to update antivirus on client computers in a network. each agent takes on a specified responsibility. first, dca roams through the network and check the last d...
