Abstract Polyhydroxyalkanoates (PHA) are a promising bio-based alternative to traditional plastics derived from petroleum. Cyanobacteria photosynthetic organisms that produce PHA CO 2 and sunlight, which can potentially reduce production costs environmental footprint in comparison heterotrophic bacteria cultures because (1) they utilize inorganic carbon sources for growth (2) do not require intensive aeration oxygenation. Moreover, supplementing precursors such as propionate, acetate,...
Within the last decade production of plastic steadily increased and so did amount waste. When bigger pieces enter environment, they are fragmented over time due to mechanical environmental forces. The occurring directly released microplastic cause severe problems on soil organisms, alteration physical properties chemical interactions in habitat. Main emissions sources different kinds abrasions (road traffic, packaging, fibers textiles during washing), waste disposal drifts. Remains mulching...
PHB-producing cyanobacteria may provide the raw material for bio-based and biodegradable plastics. To commercialize photoautotrophic PHB production, their cultivation needs to be scaled up in open systems reduce costs increase sustainability, nutrients must obtained from waste streams. Here, feasibility of these steps was verified. Different were compared laboratory-scale cultivations using either water recirculating aquaculture or pre-processed liquid digestate as nutrient sources. Then,...
The incorporation of modified bacterial cellulose derived from agricultural waste improves biodegradable composites by reducing oxygen permeability and accelerating biodegradation while maintaining mechanical properties.
Quantitative biodegradation measurement of polymers (plastic) is, usually, done by monitoring indirect parameter, such as CH4- or CO2-release oxygen consumption, which are a result microbial activity. The microorganisms in test bottle will metabolise polymer only if they can use certain part the substrate for growth new biomass (new cells). This not be measured with parameter. In our long time study we investigated wide range fast to slowly biodegradable measuring addition CO2-release. To...
Vermicompost, the digestion product of organic material by earthworms, has been widely reported to have a more positive effect on plant growth and health than conventional compost. A study was conducted investigate effects different vermicompost elutriates (aerated compost teas) soils growth. The teas were analyzed chemical, microbiological, molecular methods accompanied tests at laboratory field scale. number microorganisms in increased during extraction process affected substrate addition....
This editorial considers biosynthesis of polyhydroxyalkanoates (PHA), polymer processing PHA, and the use PHA in production bioplastics or biocomposites. The views come from a workshop aimed to join students experts working with those interested application biopolymers. goals are 1) synchronize their opinions up-to-date knowledge published literature within last 10 years, 2) formulate perspectives conclusions.
Ammoxidation of technical lignins under mild conditions is a suitable approach to artificial humic substances. However, carbohydrates as common minor constituents have been demonstrated be potential source N-heterocyclic ecotoxic compounds. Ethyl acetate extracts ammoxidation mixtures the monosaccharides glucose and xylose exhibited considerable growth inhibiting activity in OECD 201 test, with 4-methyl-1H-imidazole, 4-(hydroxymethyl)-1H-imidazole, 3-hydroxypyridine being most active The...
It was time to take stock. We modified the humipedon classification key published in 2018 make it easier and more practical. This morpho-functional taxonomy of topsoil (humipedon) only available English; we also translated into French Italian. A standardized humipedons (roughly top 30–40 cm soil: organic organomineral surface horizons) would allow for a better understanding functioning soil ecosystem. paper provides founding principles humus systems forms. With recognition few diagnostic...
Sample preparation protocols for conventional high voltage transmission electron microscopy (TEM) heavily rely on the usage of staining agents containing various heavy metals, most commonly uranyl acetate and lead citrate. However toxicity, rising legal regulations, problematic waste disposal have increased calls reduction or even complete replacement this agent. One strategies uranyless imaging is employment low-voltage microscopy. To investigate influence different final image...
Before natural plant allelochemicals can be exploited as biological pesticides against weeds and for disease control, more than the effect on target organisms needs to known. This study presents results of aquatic biotests using four organisms, namely, a water flea, freshwater alga, soil luminescent bacterium. The tested substances were 10 benzoxazinone derivatives, 3 them known wheat allelochemicals, benzoxazolin-2(3H)-one (BOA), 6-methoxybenzoxazolin-2(3H)-one (MBOA),...
The unusually shaped bacteria of the genera Stella, Labrys and Angulomicrobium have been described based on their cell morphology biochemistry. However, phylogenetic relationships remain unresolved. An earlier study that was 5S rRNA gene sequences placed genus Stella within 'Alphaproteobacteria'. In present report, polar lipids 16S genes type strains two species in humosa DSM 5900T vacuolata 5901T, are studied, as well monospecific (Labrys monachus VKM B-1479T) (Angulomicrobium tetraedrale...
The cyanobacterial genus Synechocystis is of particular interest to science and industry because its efficient phototrophic metabolism, accumulation the polymer poly(3-hydroxybutyrate) (PHB) ability withstand or adapt adverse growing conditions. One such condition increased salinity that can be caused by recycled brackish water used in cultivation. While overall reduced growth expected response salt stress, other metabolic responses relevant efficiency production biomass PHB (or both) have...
The need to switch bio-based, biodegradable and/or fully recyclable polymers is becoming increasingly clear, especially in the area of food packaging, which a major contributor plastic pollution.
