Correction: Land-based drip-irrigated culture of Ulva compressa: the effect of culture platform design and nutrient concentration on biomass production and protein content

Abstract This paper investigates the action of nanoparticles ZnO (10 nm) and TiO2 (30 nm) on growth of Saccharomyces cerevisiae CNMN-Y-20 yeast. Nanoparticles in concentration of 0,5; 1,0 and 5,0 mg/L in YPD medium did not modify significantly cell proliferation, biomass production, the carbohydrate content and the content of β-glucans at Saccharomyces cerevisiae CNMN-Y-20. Nanoparticles ZnO and TiO2 contributed to the decrease in protein content, which demonstrated the appearance of the alterations of yeast cell membranes.

Process Scale

Black Soldier fly larvae is an insect capable to convert organic waste into body biomass. The purpose of this research was to determine the productivity, mass balance of the consumption process, and content of protein and fat of prepupa which has a potency as a livestock feed. This research used 6-day-old larvae, they were fed with cassava skin that has been smoothed with a variety of feeding doses: 12.5; 25; 50; 100; and 200 (mg / larvae / day) with ratio of feed and water 2: 1. The results showed that the feeding of 200 mg / larva / day produced the best larval growth with biomass productivity of 1.54 mg / day, residue yielded of 67.1 mg / day. The organic waste was convertion into larvae biomass. In this study, approximately consumption process scale is feed successfully converted to biomass 2.77%, metabolism 6.98%, and 90.24% residue. Protein content is 25.7%. It can be concluded that the larvae are able to convert organic waste into high protein biomass and potentially being used as a livestock feed. This research acts a model to predict mass balance of substrates for feed. The benefit of this research is the science approach used in this study that can be used as a reference by researchers and the community to determine the biomass production of an organism.

A 20-year-old aspen (Populur tremloides Michx.) ecosystem was subjected to two cutting and two burning treatments. Cutting and prescribed burning were carried out on separate areas . One cutting and one burning treatment was aplied both before and after spring leaf flush. An untreated control area was set aside for comparison. Three years after treatment summer and winter aspen browse production for moose (Alcesaices) and white-tailed deer (Odocoileus virginianus) were greatest on the preflush cutting treatment (summer — 1544 kg.ha-1; winter — 395 kgha-1) followed in decreasing order by post-flush cut (summer — 635 kg.ha-1; winter — 125 kg.ha-1), postflush burn (summer — 330 kg.ha-1; winter — 96 kg.ha-1), and pre-flush burn (summer — 50 kg.ha-1; winter — no browsing). Aspen browse quality (nutrient concentration) was essentially unaffected by treatment. Post treatment biomass production of aspen is discussed in terms of known physiological and ecological responses to disturbance.

ABSTRACTFive isolates from chilled food and refrigerator inner surfaces and closely related reference strains of the speciesEscherichia coli,Listeria monocytogenes,Staphylococcus xylosus,Bacillus cereus,Pedobacter nutrimenti, andPedobacter panaciterraewere tested for the effect of growth temperature (30°C and 10°C) on biomass formation. Growth was monitored via optical density, and biomass formation was measured at the early stationary phase based on the following parameters in complex and defined media: viable cell count, total cell count, cell dry weight, whole-cell protein content, and cell morphology. According to the lack of growth at 1°C, all strains were assigned to the thermal class of mesophiles. Glucose and ammonium consumption related to cell yield were analyzed in defined media. Except for the protein content, temperature had a significant (ttest,P< 0.05) effect on all biomass formation parameters for each strain. The results show a significant difference between the isolates and the related reference strains. Isolates achieved an increase in biomass production between 20% and 110% at the 10°C temperature, which is 15 to 25°C lower than their maximum growth rate temperatures. In contrast, reference strains showed a maximum increase of only about 25%, and some reference strains showed no increase or a decrease of approximately 25%. As expected, growth rates for all strains were higher at 30°C than at 10°C, while biomass production for isolates was higher at 10°C than at 30°C. In contrast, the reference strains showed similar growth yields at the two temperatures. This also demonstrates for mesophilic bacterial strains more efficient nutrient assimilation during growth at low temperatures. Until now, this characteristic was attributed only to psychrophilic microorganisms.IMPORTANCEFor several psychrophilic species, increased biomass formation was described at temperatures lower than optimum growth temperatures, which are defined by the highest growth rate. This work shows increased biomass formation at low growth temperatures for mesophilic isolates. A comparison with closely related reference strains from culture collections showed a significantly smaller increase or no increase in biomass formation. This indicates a loss of specific adaptive mechanisms (e.g., cold adaptation) for mesophiles during long-term cultivation. The increased biomass production for mesophiles under low-temperature conditions opens new avenues for a more efficient biotechnological transformation of nutrients to microbial biomass. These findings may also be important for risk assessment of cooled foods since risk potential is often correlated with the cell numbers present in food samples.

The effects of simulated grazing and burning on biomass production, forage quality (CP and DM digestibility), plant mortality and flowering of 4 native perennial grasses (Poa phillipsiana, P. sieberana, Danthonia pilosa and Festuca asperula) and four perennial forbs (Aciphylla simplicifolia, Arthropodium milleflorum, Bulbine bulbosa and Hypochoeris radicata) growing in Kosciusko National Park were studied over a 16-month period. Cutting at 8-week intervals reduced the amount of regrowth at successive harvests as well as the survival of individuals. The season in which a single cut was made generally had a greater effect on the amount of regrowth than length of the regrowth period. Burning promoted flowering and improved the forage quality of the grasses. Rabbits bred only when they were able to obtain forage with a minimum protein content of 14%, provided mainly by the forb species. The management implications resulting from the interaction of fire and grazing, particularly by rabbits and domestic stock, for ecosystem quality are discussed.

Abstract Climate change effects on natural and managed ecosystems are difficult to predict due to its multi-factor nature. However, most studies which investigate the impacts of climate change factors on plants, such as warming or drought, were conducted under one single stress and controlled environments. In this study, we evaluated the effects of elevated temperature (+ 2°C) (T) under different conditions of soil water availability (W) to understand the interactive effects of both factors on leaf, stem, and inflorescence macro and micronutrients concentration and biomass allocation of a tropical forage species, Stylosanthes capitata Vogel under field conditions. Temperature control was performed by a Temperature Free-Air Controlled Enhancement (T‐FACE) system. We observed that warming changed nutrient concentrations and plant growth depending on soil moisture levels, but the responses were specific for each plant-organ. In general, we observed that warming under well-watered conditions greatly improved nutrient concentration and biomass production, whilst the opposite effect was observed under non-irrigated and non-warmed conditions. However, under warmed and non-irrigated conditions, we observed that leaf biomass and leaf nutrient concentration greatly reduced when compared to non-warmed and irrigated plants. Our findings suggest that warming (2°C above ambient temperature) and drought, as well as both combined stresses, will change the nutrient requirements and biomass distributions between plant aerial organs of S. capitata in tropical ecosystems, which may impact animal feeding in the future.
