“…The profile of the microalgal biomass is presented in Table 2. Initial microalgal biomass with dry organic matter levels (VS) and chlorophyll levels during the exact experiment were kept at 200 mg VS/dm 3 and 0.1 µg/dm 3 . In all of the variants, P. subcordiformis was cultured over a period of 11 days.…”

“…Pushing forward the development and widespread take-up of environmentally-friendly, efficient and costeffective biomass production technologies represents an ongoing challenge to scientists, as well as a priority issue for operators of energy systems [1]. There have been numerous attempts to demonstrate that typical land energy crops can be used for this purpose [2,3]. However, the use of such plants requires appropriate agrotechnical procedures, marginal/degraded soils, natural fertilizers, as well as species of energy crops that must be carefully selected, fast-growing and resistant to environmental conditions [4].…”

P. subcordiformis is a potentially promising species with commercial, environmental and technological viability for industrial applications. The great potential of these microalgae lies in their fast biomass growth, pollution resistance, and compatibility with different culture media. This study aimed to determine the efficiency of P. subcordiformis biomass production in a medium prepared with water from the Bay of Gdańsk. The tested medium supported high biomass growth rates which reached 317.58 ± 42.31 mg V S /dm 3 •d in the best-performing variant, with a final concentration of 3493.3 ± 465.4 mg V S /dm 3 •d. In the autotrophic culture, nitrogen and phosphorus removal exceeded 98%. Amending the mixotrophic culture with glucose did not affect P. subcordiformis concentrations. However, it did significantly limit the demand for nutrients in the biomass and reduced chlorophyll a production in the cells.

Growing of highly productive perennial plants becomes the guarantee of opportunity of stable provision with raw materials for the production of solid biofuels in modern conditions. The purpose of the research was to increase yielding capacity of Miscanthus biomass at the expense of the nutritional background and foliar top dressing. Four-year observations of the condition of Miscanthus plantations were performed at Station in the Forest-steppe zone of Ukraine during 2016-2019. Over the years of observations, a noticeable effect of background nutrition in combination with foliar feeding, plant growth regulators and growth stimulants and their one-time and double treatments has been revealed. The highest result was obtained in 2016 with an excessive amount of moisture during the growing season-392 mm. In the first variant of factor A with the one-time treatment by means of preparation Quantum Gold the leaf surface was 46.7 thousand m 2 /ha; on the nutritional background N 30 P 30 K 30 with one-time treatment by means of preparation Vympel-K-45.6 thousand m 2 /ha; with increase of the dose of mineral fertilizers on the nutritional background twice (N 60 P 60 K 60) at one-time treatment with the preparation Vympel-K the leaf surface was 45 thousand m 2 /ha. The lowest results were obtained in 2017, when 183 mm of precipitation was registered during the entire growing season. In the first variant of the same factor A at one-time treatment with the preparation Quantum Gold the leaf surface was 3.8 thousand m 2 /ha, in the second variant, when treated with the preparation Vympel-K, its leaf surface was 7.4 thousand m 2 /ha, in the third variant (control)-11.4 thousand m 2 /ha. In the control variants of factor B, the leaf surface area with the application of mineral fertilizers (second and third variants of factor A) increased. In consideration of the data obtained, it can be argued that the application of mineral fertilizers had the positive effect on plant growth and development, even with a critically minimal amount of precipitations. The application of the preparation Quantum Gold significantly affects the growth and development of the aboveground part of the Miscanthus gigantic. The application of the preparation Vympel-K stimulates the development of the root system and increases the yielding capacity of the investigated crop.

“…Reducing the amounts of greenhouse gases released into the atmosphere will contribute significantly to counteracting the global warming effect. One of the most effective technologies involving the use of lignocellulosic biomass is the production of biofuels, including methane-rich biogas [5]. However, in order to use the biogas generated in biogas plants for energy and transport purposes, it is necessary to upgrade the biogas to the quality of biomethane, as a fuel for vehicles.…”

Progress in the Production of Biogas from Maize Silage after Acid-Heat Pretreatment

et al. 2021

One of the most effective technologies involving the use of lignocellulosic biomass is the production of biofuels, including methane-rich biogas. In order to increase the amount of gas produced, it is necessary to optimize the fermentation process, for example, by substrate pretreatment. The present study aimed to analyze the coupled effects of microwave radiation and the following acids: phosphoric(V) acid (H3PO4), hydrochloric acid (HCl), and sulfuric(VI) acid (H2SO4), on the destruction of a lignocellulosic complex of maize silage biomass and its susceptibility to anaerobic degradation in the methane fermentation process. The study compared the effects of plant biomass (maize silage) disintegration using microwave and conventional heating; the criterion differentiating experimental variants was the dose of acid used, i.e., 10% H3PO4, 10% HCl, and 10% H2SO4 in doses of 0.02, 0.05, 0.10, 0.20, and 0.40 g/gTS. Microwave heating caused a higher biogas production in the case of all acids tested (HCl, H2SO4, H3PO4). The highest biogas volume, exceeding 1800 L/kgVS, was produced in the variant with HCl used at a dose of 0.4 g/gTS.
