EFSA is requested to assess the safety of a broad range biological agents in context notification for market authorisation as sources food and feed additives, enzymes plant protection products. The qualified presumption (QPS) assessment was developed provide harmonised generic pre-assessment support risk assessments performed by EFSA's scientific Panels. unambiguously defined (at highest taxonomic unit appropriate purpose which an application intended), completeness body knowledge are...
The qualified presumption of safety (QPS) approach was developed to provide a regularly updated generic pre-evaluation the biological agents, intended for addition food or feed, support work EFSA's Scientific Panels. It is based on an assessment published data each agent, with respect its taxonomic identity, body knowledge, concerns and antimicrobial resistance. Safety identified unit (TU) are, where possible, confirmed at strain product level, reflected by 'qualifications'. In period...
The qualified presumption of safety (QPS) was developed to provide a pre-assessment within EFSA for microorganisms. Strains belonging QPS taxonomic units (TUs) still require an assessment based on specific data package, but status facilitates fast track evaluation. TUs are unambiguously defined biological agents assessed the body knowledge, their and end use. Safety concerns are, where possible, be confirmed at strain or product level, reflected as 'qualifications'. Qualifications need...
Following a request from EFSA, the Panel on Plant Protection Products and their Residues developed an opinion science behind risk assessment of plant protection products for in-soil organisms.The current scheme is reviewed, taking into account new regulatory frameworks scientific developments.Proposals are made specific goals organisms being key drivers relevant ecosystem services in agricultural landscapes such as nutrient cycling, soil structure, pest control biodiversity.Considering...
Abstract Biological control , or biocontrol is the exploitation of living agents (incl. viruses) to combat pestilential organisms pathogens, pests, and weeds) for diverse purposes provide human benefits. Thus, during last century practices concepts involved have evolved in separate streams associated with distinct scientific taxonomic disciplines. In parallel developments, there been increasing references biological industrial contexts legislation, resulting conceptual terminological...
The qualified presumption of safety (QPS) approach was developed to provide a generic pre-evaluation the biological agents. QPS is based on an assessment published data for each agent, with respect its taxonomic identity, body relevant knowledge and concerns.

The qualified presumption of safety (QPS) process was developed to provide a assessment approach for microorganisms intended use in food or feed chains. QPS is based on an published data each taxonomic unit (TU), with respect its identity, the body relevant knowledge and concerns. Safety concerns identified TU are, where possible, confirmed at species/strain product level reflected by 'qualifications'. In period covered this Statement, no new information found that would change status...
Water-column methane oxidation can represent a substantial carbon transformation pathway in lakes, and circumstantial evidence indicates that may be potentially important source of for pelagic food webs. We estimated methanotrophic bacterial production (MBP), growth efficiency (MBGE), heterotrophic (HBP), primary (PP), the relative contribution bacteria to overall biomass three very different lakes during summer winter. In addition, we measured stable isotope ratios particulate organic...
Biological oxidation of CH(4) is an important constraint on the emission this gas from areas, such as landfills to atmosphere. We studied effect temperature methanotrophic bacteria in three different landfill cover soils, incubated laboratory. In samples a young cover, consisting wood chips and sewage sludge, phospholipid fatty acids (PLFAs), regarded biomarkers for type I methanotrophs (16:1omega5t, 16:1omega6c, 16:1omega8c), primarily increased at low temperatures (5-10 degrees C). On...
Following a request from EFSA, the Panel on Plant Protection Products and their Residues (PPR) developed an opinion state of art Toxicokinetic/Toxicodynamic (TKTD) models use in prospective environmental risk assessment (ERA) for pesticides aquatic organisms. TKTD are species- compound-specific can be used to predict (sub)lethal effects under untested (time-variable) exposure conditions. Three different types described, viz., (i) 'General Unified Threshold Survival' (GUTS), (ii) those based...

Abstract The qualified presumption of safety (QPS) process was developed to provide a assessment approach for microorganisms intended use in food or feed chains. In the period covered by this statement, no new information found that would change status previously recommended QPS TUs. TUs list were updated based on verification, against their respective authoritative databases, correctness names and completeness synonyms. A procedure has been established ensure are kept up date relation...
Analyses of phospholipid fatty acids (PLFAs) were used to assess variation in community structure and total microbial biomass two boreal peatlands Sweden. The PLFA concentration peat ranged from 0.16 7.0 nmol g wet peat(sup-1) (median, 0.70 peat(sup-1)). Principal-component analysis data revealed that the degree depth-related composition was high among peatland habitats, with general differences between sites, water tables within a few centimeters moss surface, dry >10 cm below surface....
In this paper we present a model that can reconstruct water table position and soil temperature profiles to 3 m depth in boreal mixed mire systems using the readily available climate data on air precipitation as driving variables. The simulates complete, multiple annual cycles including winter conditions freeze‐thaw processes. major requisite for an accurate description of heat flux is content profile because high porosity thermal properties water. moisture described function derived from...
ABSTRACT The abundance and activity of methane-oxidizing bacteria (MOB) in the water column were investigated three lakes with different contents nutrients humic substances. MOB was determined by analysis group-specific phospholipid fatty acids from type I II MOB, situ measured a 14 CH 4 transformation method. acid analyses indicated that most similar to species Methylomonas , Methylomicrobium Methylosarcina made substantial contribution (up 41%) total bacterial biomass, whereas generally...
Large amounts of the greenhouse gas methane (CH4) are produced by anaerobic mineralization organic matter in lakes. In spite extensive freshwater CH4 emissions, most is typically oxidized oxidizing bacteria (MOB) before it can reach lake surface and be emitted to atmosphere. turn, has been shown that CH4-derived biomass MOB provide energy carbon for zooplankton macroinvertebrates. this study, we demonstrate presence specific fatty acids synthesized fish tissues having low stable isotope...
