“…Each experiment was performed in triplicate. The experimental units were kept under in controlled conditions such as 23 • C and 12 h of photoperiod, according to the Biotechnology Laboratory at the Federal University of São Carlos (UFSCar) in Brazil (Camargo & Lombardi, 2018). On days 1, 3, 5, 7, and 9, optical densities (OD) were measured using 1 ml of N. ellipsosporum liquid culture and a spectrophotometer (Mettler Toledo) at 650 nm.…”

Mathematical models provide information about population dynamics under different conditions. In the study, four models were evaluated and employed to describe the growth kinetics of Nostoc ellipsosporum with different light wavelengths: Baranyi-Roberts, Modiﬁed Gompertz, Modiﬁed Logistic, and Richards. N. ellipsosporum was grown in BG-11 liquid medium for 9 days, using 12 hours of photoperiod and the following treatments: white light (400-800 nm), red light (650-800 nm), yellow light (550-580 nm) and blue light (460-480 nm). Each experiment was performed in triplicate. The optical density (OD) was measured on days 1, 3, 5, 7 and 9, using a spectrophotometer at 650 nm. The maximum cell growth was obtained under white light (OD650 : 0.090 ± 0.008), followed by the yellow light (OD650 :0.057 ± 0.004). Conversely, blue light showed a marked inhibitory effect on the growth of N. ellipsosporum (OD650 : 0.009 ± 0.001). The results revealed that the Baranyi-Roberts model had a better ﬁt with the experimental data from N. ellipsosporum growth in all four treatments. The ﬁndings from this modeling study could be used in several biotechnological applications that require the productionof N. ellipsosporum and its bioproducts.

“…The absorbance of the leaf extract was measured with a UV-visible spectrophotometer (Model UV-1800, Shimadzu, Japan) at 645 nm and 663 nm. TCC was determined following the method given by Singh et al [7] using the formula: where A 645 = absorbance at 645 nm, A 663 = absorbance at 663 nm, V = total volume of the extract in millilitre (mL), W = weight of leaf materials in gram.…”

Sensitivity study of plant species due to traffic emitted air pollutants (NO2 and PM2.5) during different seasons in Dhaka, Bangladesh

The impact of traffic emitted nitrogen dioxide (NO 2) and fine particulate matter (PM 2.5) on various plant species (Polyalthia longifolia, Swietenia mahagoni, Artocarpus heterophyllus) during different seasons (summer, rainy, and winter) was studied in greater Dhaka city (traffic, residential, and control site), Bangladesh. Air pollution tolerance index (APTI) of these plant species was determined from the measured concentrations of total chlorophyll content (TCC), ascorbic acid (AAC), relative water content (RWC), and pH of the leaf extract. TCC and AAC concentrations in leaves species were determined with UV-visible spectrophotometer. NO 2 concentration was determined with Aeroquel (New Zealand), and PM 2.5 was determined with Aerocet (USA). The measured NO 2 and PM 2.5 concentrations at each sampling location were used to establish a relationship with the determined APTI values. The average value of TCC, AAC, and RWC was found much lower in traffic site compared than that of the control site. High pollution stress on plants was also found in traffic sites showing 30% lower APTI values. The plants become sensitive if the APTI value is smaller than or equal to 12 (APTI ≤ 12). However, the average APTI values in different seasons showed a significant variations and followed the sequence-rainy season (8.10) > summer (7.34) > winter (6.69). The plants had the highest sensitivity towards pollutants during winter time. The average APTI values also varied depending on the locations and plant species with a total average of 7.38 ± 1.17, which indicates the sensitivity of plants towards pollution. On average, the measured concentration of NO 2 was 223 ± 0.15 μg m −3 and PM 2.5 mass was 125.7 ± 0.05 μg m −3. The APTI values showed a strong negative correlation with traffic emitted pollutants NO 2 (R 2 = 0.86) and PM 2.5 (R 2 = 0.70) indicating threats towards the plants survival.

“…There have been many other studies into the effect of flue gas concentration on microalgae productivity [38][39][40][41][42][43] , as well as some recent investigations into the effects of flue gas on microalgae physiology and biochemistry [44][45][46][47][48] . Broadly, there are two options for directly using raw flue gas containing NOx and SOx to enhance microalgal growth at large scale.…”

Microalgae have great, yet relatively untapped potential as a highly productive crop for the production of animal and aquaculture feed, biofuels, and nutraceutical products. Compared to conventional terrestrial crops they have a very fast growth rate and can be produced on non-arable land. During microalgae cultivation, carbon dioxide (CO2) is supplied as the carbon source for photosynthesising microalgae. There are a number of potential CO2 supplies including air, flue gas and purified CO2. In addition, several strategies have been applied to the delivery of CO2 to microalgae production systems, including directly bubbling CO2-rich gas, microbubbles, porous membrane spargers and non-porous membrane contactors. This article provides a comparative analysis of the different CO2 supply and delivery strategies and how they relate to each other.
