TL;DR: Two purple nonsulfur bacteria strains, Rhodobium marinum NW16 and Rhodobacter sphaeroides KMS24, were investigated for their potential to remove heavy metals from contaminated shrimp pond water and altered the cellular morphology of both strains and accumulated HMs were found in their cells.

TL;DR: In this paper, the optimal conditions for producing functional fermented red seaweed beverage (FSB) were established using Central Composite Design by varying the amounts of monosodium glutamate (MSG), sucrose and the initial pH in MRS medium.

TL;DR: Lipase production was the result of a synergistic combination of effective parameters interactions and these parameters were in equilibrium, according to a modeling assessment of strain AFNA and its correlation with bacterial growth.

TL;DR: In this paper, the authors determined the methanogenic toxicity effect of free ammonia contained in swine wastewater comparing raw swine waste (RW) and the liquid fraction of SWW (TW).

TL;DR: The isolate, Amphibacillus sp.

TL;DR: Phylogenetic analysis of the mixed culture revealed that members involved hydrogen producers in both batch and continuous reactors were phylogenetically related to the Thermoanaerobacterium thermosaccharolyticum .

TL;DR: Significant QTLs detected in this study can be employed in MAS for molecular breeding programs aiming at developing drought tolerant cotton cultivars through molecular marker-assisted breeding.

TL;DR: The results suggest that the high degree of EST-SSRs transferability to Linum species can be a useful enhancement of the current database of SSR markers for future genetic and evolutionary studies.

TL;DR: The saccharification of lignocellulosic substrates by enzyme produced by A. oryzae ITCC 4857.01 indicates the enzymes specificity towards the substrates and will lead to efficient conversion of cellulose materials to other important products.

TL;DR: In this article, the authors used DSY as a low-cost nitrogen supplement for ethanol fermentation from sweet sorghum juice under very high gravity (VHG) conditions by Saccharomyces cerevisiae NP 01.

TL;DR: An automated colony picker, Clone Pix FL system was used to replace limiting dilution method and was able to screen 1 x 10 5 clones secreting humanized monoclonal antibodies and high producer clones were selected in just 7 days.

TL;DR: The effects of fermentation temperatures and yeast strain type on beer quality and spent yeast density produced after wort fermentation by two commercial yeast strains were investigated in this paper, and the results showed that there was no significant difference in colour intensity between the beers produced at different fermentation temperatures.

TL;DR: In this paper, the efficiency of sugar cane bagasse (SCB) and vegetable sponge (VS), two natural adsorbents commonly found in Brazil, for retaining paracetamol molecules dispersed in aqueous solutions was evaluated.

TL;DR: In this article, the effect of pH and temperature on dye uptake was also investigated and kinetic parameters were determined, including optimal initial pH (3.0), equilibrium time (2 hrs), initial dye concentration ( 100 mg l -1 ) and biomass concentration (1.2 mg l −1 ) were determined at 26oC.

TL;DR: In this article, the aerobic degradability of nonylphenol ethoxylates (NPEOs) by the acclimated microorganisms in active sludge was examined using shaking-flask tests, and the degradation of benzene rings in NPEOs was determined using UV spectroscopy and high performance liquid chromatography (HPLC).

TL;DR: In this paper, the effect of feeding rate (0.10-0.15 L h -1 ) on 1,3-propanediol production was studied in fed-batch fermentation, where the optimal condition was 60 g l -1 crude glycerol, pH control at 6.5 and cultivation temperature at 37oC.

TL;DR: AFLP is an efficient tool for determination of genetic diversity of cabbage gene bank accessions and ten selective primer pairs were found to be most informative because each of these uniquely identified all of the accessions used.

TL;DR: Investigation of the knowledge and acceptance of genetically modified organisms among prospective teachers in Slovenia and Turkey revealed that knowledge of genetics and biotechnology barely influenced the acceptability of genetic modification, and correlations are low.

TL;DR: It has been found that the best condition for CLEAs preparation are to use glutaraldehyde as cross-linking reagent at pH 9.5, at a concentration of 3.5 g/l, and an enzyme/albumin ratio of 15.2%.

TL;DR: In this paper, a low-cost media for the production of LAB plantarum biomass was proposed, where distillery waste is combined with a byproduct from a sugar production, molasses, to form a medium for the growth of Lactobacillus plantarrum with yields and biomass densities comparable with conventional industrial media.

TL;DR: In this article, an inertizing and cooling process for grapes cryomaceration has been set up, which works with a grape flow of approximately 2-3 tons/h, with a maximum thermal gradient of 20 K between the grape inlet and outlet temperature.

TL;DR: The filamentous fungus A. phoenicis produced high levels of β-D-fructofuranosidase (FFase) when grown for 72 hrs under Solid-State Fermentation (SSF), using soy bran moistened with tap water (1:0.5 w/v) as substrate/carbon source.

TL;DR: The objective of this study was to investigate the effect of vermicompost, worm-bed leachate (WBL) and Glomus mosseae, an arbuscular mycorrhizal fungi (AMF) on growth of lemongrass and its composition.

TL;DR: The objectives of this study were to investigate whether 17β-estradiol could be measured from individual cow milk samples using a commercially available non-radiolabelled enzyme immunoassay kit (EIA) with no previously reported milk application, and whether those detections could precisely illustrate 17 β-mostradiol pre-ovulation peak.
