  text: 'Winter cover crops (CCs) provide substantial agronomic and environmental
    benefits, yet their influence on nitrogen (N) fertilization requirements and yield
    outcomes for subsequent crops remains underexplored. This study investigates the
    economic optimal nitrogen rates (EONRs) and corresponding yield effects for first
    (silage maize or sugar beet) and second (winter wheat) succeeding crops following
    CCs. Four CC species from different functional groups were compared to a bare
    fallow control on contrasting sandy and loamy soils across four German field sites
    over two consecutive cropping sequences. Results revealed opposing effects: reduced
    EONR and increased N use efficiency on sandy soils in silage maize sequences,
    particularly following oil radish and rye CCs, but increased EONR on loamy soils
    for sugar beet sequences, with vetch CC showing the most favourable outcomes.
    Yield impacts varied by CC type and soil, with oil radish consistently enhancing
    yields across sites. However, CC effects on EONR were not correlated with pre-winter
    N uptake in CC biomass, challenging simple N budgeting practices. Environmental
    analysis highlighted potential greenhouse gas savings via reduced fertilizer inputs
    on sandy soils but increased upstream emissions on loamy sites. These findings
    emphasize the need for site-specific CC selection to balance economic and environmental
    benefits, with oil radish and vetch emerging as optimal choices in our trials
    for sandy and loamy soils, respectively.'

  text: Continuous processes offer more environmentally friendlier beer production
    compared to the batch production. However, the continuous production of mashing
    has not become state-of-the-art in the brewing industry. The controllability and
    flexibility of this process still has hurdles for practical implementation, but
    which are necessary to react to changing raw materials. Once overcome, a continuous
    mashing can be efficiently adapted to the raw materials. Both mean residence time
    and temperature were investigated as key parameters to influence the extract and
    fermentable sugar content of the wort. The continuous mashing process was implemented
    as continuous stirred tank reactor (CSTR) cascade consisting of mashing in (20°C),
    protein rest (50°C), β-amylase rest (62-64°C), saccharification rest (72°C) and
    mashing out (78°C). Two different temperature settings for the β-amylase rest
    were investigated with particular emphasis on fermentable sugars. Analysis of
    Variance (ANOVA) and a post-hoc analysis showed that the mean residence time and
    temperature settings were suitable control parameters for the fermentable sugars.
    In the experimental conditions, the most pronounced effect was with the β-amylase
    rest. These results broaden the understanding of heterogenous CSTR mashing systems
    about assembly and selection of process parameters

  text: 'n recent decades, the demand for palm oil has constantly increased and with
    it the cultivation of oil palms. After a period of 25 years, the oil yield of
    the palm trees decreases and they are felled. The trees are cut into pieces and
    remain on the plantations. However, due to their high moisture and sugar content,
    fungi and molds cause problems for replanting. The use of the wood for the timber
    industry is difficult due to its structural characteristics. Biotechnological
    processes use microorganisms to produce relevant industrial products. The basis
    for each process is a culture medium that contains all necessary nutrients, especially
    carbohydrates. The culture medium makes up a high percentage of the costs, so
    alternative, cheaper substrates are preferred. In this review, we show and compare
    different analyses of the sap mechanically pressed from the oil palm trunk regarding
    its sugar and nutrient content. The total sugar concentration in the palm sap
    varies between 16.97–140 g L<jats:sup>−1</jats:sup> and it is mainly composed
    of glucose, fructose, and sucrose. The comparison with common nutrient media and
    the results of fermentation processes already carried out on a laboratory scale
    show that palm sap offers great potential as a fermentation medium for biotechnological
    conversion into industrially relevant products. '

  text: Near infrared spectroscopy in combination with a transflection probe was investigated
    as inline measurement in a continuous flash pasteurizer system with a sugar-water
    model solution. Robustness and reproducibility of fluctuations of recorded spectra
    as well as trueness of the chemometric analysis were compared under different
    process parameter settings. Variable parameters were the flow rate (from laminar
    flow at 30 L/h to turbulent flow at 90 L/h), temperature (20 to 100 degrees C)
    and the path length of the transflection probe (2 and 4 mm) while the pressure
    was kept constant at 2.5 bar. Temperature and path length were identified as the
    most affecting parameters, in case of homogenous test medium. In case of particle
    containing systems, the flow rate could have an impact as well. However, the application
    of a PLS model, which includes a broad temperature range, and the correction of
    prediction results by applying a polynomial regression function for prediction
    errors, was able to compensate these effects. Also, a path length of 2 mm leads
    to a higher accuracy. The applied strategy shows that by the identification of
    relevant process parameters and settings as well as the establishment of a compensation
    strategy, near infrared spectroscopy is a powerful process analytical tool for
    continuous flash pasteurization systems.
