Effects of anaerobic digestion on digestate nutrient availability and crop growth: A review Tập 12 Số 3 - Trang 242-257 - 2012
Kurt Möller, Torsten Müller
Anaerobic digestion (AD) for biogas production leads to several changes in the
composition of the resulting digestates compared to the original feedstock
(ammonia content, pH, carbon to nitrogen ratio, etc.), which are relevant for
the plant availability of macro‐ and micronutrients after field application.
Increased NH4+‐N content in digested slurries compared to undigested slurries

Removal of Heavy Metals from the Environment by Biosorption Tập 4 Số 3 - Trang 219-232 - 2004
Maria Gavrilescu
AbstractThe pollution of the environment with toxic metals is a result of many
human activities, such as mining and metallurgy, and the effects of these metals
on the ecosystems are of large economic and public‐healthsignificance. This
paper presents the features and advantages of the unconventional removal method
of heavy metals – biosorption – as a part of bioremediation. Bioremediation

Sulfate Reduction Based Bioprocesses for the Treatment of Acid Mine Drainage and the Recovery of Metals Tập 7 Số 6 - Trang 541-564 - 2007
Anna H. Kaksonen, Jaakko A. Puhakka
AbstractBiological sulfate reduction is increasingly replacing chemical unit
processes in mining biotechnology. Sulfate reducing bacteria (SRB) can be used
for treating ground‐ and surface waters contaminated with acid mine drainage
(AMD), and for recovering metals from wastewater and process streams.
Biologically produced H2S precipitates metals as metal sulfides, while biogenic
bicarbonate alkal... hiện toàn bộ
Anaerobic digestion technology in livestock manure treatment for biogas production: A review Tập 12 Số 3 - Trang 258-269 - 2012
Ismail Muhammad Nasir, Tinia Idaty Mohd Ghazi, Rozita Omar
This article reviews the potential of anaerobic digestion (AD) for biogas
production from livestock manure wastes and compares the operating and
performance data for various anaerobic process configurations. It examines
different kinds of manure waste treatment techniques and the influence of
several parameters on biogas and methane yield. The comparison indicates that a
variety of different opera... hiện toàn bộ
Elicitation: A biotechnological tool for enhanced production of secondary metabolites in hairy root cultures Tập 19 Số 12 - Trang 880-895 - 2019
Mihir Halder, Sayantika Sarkar, Sumita Jha
AbstractElicitation is a possible aid to overcome various difficulties
associated with the large‐scale production of most commercially important
bioactive secondary metabolites from wild and cultivated plants,
undifferentiated or differentiated cultures. Secondary metabolite accumulation
in vitro or their efflux in culture medium has been elicited in the
undifferentiated or differentiated tissue c... hiện toàn bộ
Microbial Processes of Heavy Metal Removal from Carbon‐Deficient Effluents in Constructed Wetlands Tập 4 Số 5 - Trang 403-411 - 2004
Д. Б. Косолапов, Peter Kuschk, Mikhail Vainshtein, A.V. Vatsourina, Arndt Wießner, Matthias Kästner, R. Müller
AbstractThis paper reviews the main microbial processes involved when toxic
metals are removed from wastewater in constructed wetlands. Microbial activity
is thought to play a key role in the detoxification of these metals. The paper
concentrates on the microbial processes which affect the mobility, the toxicity
and bioavailability of metals, namely biosorption, metal sulfide precipitation
by sulf... hiện toàn bộ
Development of Active Antimicrobial Fiber‐Based Chitosan Polysaccharide Nanostructures using Electrospinning Tập 8 Số 3 - Trang 303-314 - 2008
Sergio Torres‐Giner, M.J. Ocio, José M. Lagarón
AbstractThe electrospinning technology opens up enormous possibilities for the
implementation of bio‐based materials and food hydrocolloids in numerous
applications. In this context, chitosan is a sustainable, biocompatible,
biodegradable, antimicrobial and non‐toxic polysaccharide of great relevance in
many fields of application. Because of its abundance in nature and excellent
biocompatibility, ... hiện toàn bộ
Screening of bacterial strains capable of converting biodiesel‐derived raw glycerol into 1,3‐propanediol, 2,3‐butanediol and ethanol Tập 12 Số 1 - Trang 57-68 - 2012
Maria Metsoviti, Spiros Paramithiotis, Eleftherios H. Drosinos, Maria Galiotou‐Panayotou, George‐John E. Nychas, An‐Ping Zeng, Séraphim Papanikolaou
AbstractThe ability of bacterial strains to assimilate glycerol derived from
biodiesel facilities to produce metabolic compounds of importance for the food,
textile and chemical industry, such as 1,3‐propanediol (PD), 2,3‐butanediol (BD)
and ethanol (EtOH), was assessed. The screening of 84 bacterial strains was
performed using glycerol as carbon source. After initial trials, 12 strains were

Influence of carbon and nitrogen concentration on itaconic acid production by the smut fungus Ustilago maydis Tập 14 Số 2 - Trang 129-134 - 2014
Nicole Maaßen, Monika Maasem Panakova, Nick Wierckx, Elena Geiser, Martín Zimmermann, Michael Bölker, Ulrich Klinner, Lars M. Blank
Itaconic acid is a valuable platform compound for the production of bio‐based
polymers, chemicals, and fuels. Ustilago maydis is a promising host for the
production of itaconic acid from biomass‐derived substrates due to its
unicellular growth pattern and its potential to utilize biomass‐derived sugar
monomers and polymers. The potential of U. maydis for industrial itaconate
production was assesse... hiện toàn bộ
