Efficient production of α-acetolactate by whole cell catalytic transformation of fermentation-derived pyruvate

open access: yesMicrobial Cell Factories, 2019
Background Diacetyl provides the buttery aroma in products such as butter and margarine. It can be made via a harsh set of chemical reactions from sugarcane bagasse, however, in dairy products it is normally formed spontaneously from α-acetolactate, a ...

Target-site and non-target-site resistance mechanisms to ALS inhibiting herbicides in Papaver rhoeas [PDF]

open access: yes, 2017
Target-site and non-target-site resistance mechanisms to ALS inhibitors were investigated in multiple resistant (tribenuron-methyl and 2,4-D) and only 2,4-D resistant, Spanish corn poppy populations.

Efficient production of acetoin by fermentation using the newly isolated mutant strain Lactococcus lactis subsp. lactis CML B4 [PDF]

open access: yes, 2017
With the aim of applying biotechnology to produce acetoin, a chemical that can be used as an aroma and as a building block for other compounds, several putative mutants with reduced lactic acid synthesis were obtained from a wild-type homolactic strain ...

Degradative acetolactate synthase of Bacillus subtilis: purification and properties [PDF]

open access: yesJournal of Bacteriology, 1975
A degradative acetolactate synthase (acetolactate pyruvate-lyase [carboxylating], EC 4.1.3.18) from Bacillus subtilis has been partially purified and characterized. The synthesis of the enzyme was induced by growth of cells in minimal medium plus isobutyrate or acetate. The enzyme was partially purified by ammonium sulfate fractionation, gel filtration,

Resistance of Amaranthus retroflexus to acetolactate synthase inhibitor herbicides in Brazil [PDF]

open access: yesPlanta Daninha, 2014
When in competition with cotton, Amaranthus retroflexus can cause high yield losses. Due to the limited availability of selective herbicides registered for post emergence control of this weed, the same herbicides have been used repeated times over the ...

Importance of herbicide-tolerant sunflower hybrids in suppressing common ragweed (Ambrosia artemisiifolia) pollen production. Minireview [PDF]

open access: yes, 2013
Common ragweed (Ambrosia artemisiifolia) is the number one weed in Hungary: it covers ca. 5% of the arable land, causing huge losses in row crops, especially in sunflowers. In addition, because of the high allergenicity of its pollen, common ragweed is a

Characterization of Two Forms of Acetolactate Synthase from Barley [PDF]

open access: yesBMB Reports, 2003
Acetolactate synthase (ALS) catalyzes the first common step in the biosynthesis of valine, leucine, and isoleucine. ALS is the target site for several classes of herbicides, including sulfonylureas, imidazolinones, and triazolopyrimidines. Two forms of ALS (designated ALS I and ALS II) were separated from barley shoots by heparin affinity column ...

RESPONSE OF SENSITIVE CORN HYBRIDS TO THE ASSOCIATION OF NICOSULFURON AND TIMING OF NITROGEN APPLICATION

open access: yesCiência Agrícola, 2019
Nicosulfuron is an herbicide used in corn crop for controlling weeds, some hybrids are sensitivity to nicosulfuron even more when it is applied near to the application of nitrogen fertilizers.

Stable isotope profiles reveal active production of VOCs from human-associated microbes. [PDF]

open access: yes, 2017
Volatile organic compounds (VOCs) measured from exhaled breath have great promise for the diagnosis of bacterial infections. However, determining human or microbial origin of VOCs detected in breath remains a great challenge.

Response of Herbicide-Resistant Palmer Amaranth (Amaranthus palmeri) Accessions to Drought Stress

open access: yesInternational Journal of Agronomy, 2013
Palmer amaranth is a very problematic weed in several crops in the southern USA due to its competitive ability and resistance to herbicides representing different mechanisms of action.
