“…Furthermore, this pigment has several biotechnological applications for several industries, such as food, feed or pharmaceutical [71][72][73]. In this context, several studies have been conducted in order to optimize microalgae chlorophyll production [22,[74][75][76]. Growth media with lower nitrogen and phosphorus content have been shown to decrease chlorophyll production, while phosphorus-enriched growth media have revealed to be a chlorophyll production promoter [77,78].…”

The need to reduce the costs associated with microalgae cultivation encouraged scientific research into coupling this process with wastewater treatment. Thus, the aim of this work was to assess the growth of Chlorella vulgaris (Chlorophyta) in different effluents from a municipal wastewater treatment plant (WWTP), namely secondary effluent (SE) and sludge run-off (SR). Assays were performed, under the same conditions, in triplicate with 4 dilution ratios of the wastewaters (25%, 50%, 75% and 100%) with the standard culture medium bold basal medium double nitrated (BBM2N) as a control. The capability of C. vulgaris for biomass production, chlorophyll synthesis and nutrients removal in the SE and SR was evaluated. The 25% SE and 25% SR showed increased specific growth rates (0.47 and 0.55 day−1, respectively) and higher biomass yields (8.64 × 107 and 1.95 × 107 cells/mL, respectively). Regarding the chlorophyll content, the 100% SR promoted the highest concentration of this pigment (2378 µg/L). This green microalga was also able to remove 94.8% of total phosphorus of SE, while in 50% SR, 31.2% was removed. Removal of 73.9% and 65.9% of total nitrogen in 50% and 100% SR, respectively, was also observed. C. vulgaris growth can, therefore, be maximized with the addition of municipal effluents, to optimize biomass production, while cleansing the effluents.

“…Panjang gelombang pendek dapat menyimpan energi lebih tinggi pada saat terjadinya proses fotosintesis (Muhammad et al, 2013). Fakhri et al (2017) mengemukakan perbedaan intensitas cahaya dan unsur hara menyebabkan perbedaan morfologi dan kandungan klorofil-a, serta karotenoid.…”

“…Karotenoid merupakan pigmen asessoris yang secara fisiologis fungsinya melindungi kerusakan klorofil-a. Pagi dan sore hari konsentrasi karotenoid memiliki nilai yang lebih tinggi dibandingkan dengan siang hari, hal ini kemungkinan disebabkan oleh pengaruh radiasi ultraviolet yang dikenal dengan photoinhibition (hambatan oleh cahaya) dan photodamage (kerusakan oleh cahaya) serta photooxidation (oksidasi oleh cahaya) yang disebabkan cahaya yang terlalu tinggi (Fakhri et al, 2017). Kandungan pigmen karotenoid dalam perairan pada pagi dan sore hari ini lebih besar dikarenakan organisme fotosintetik salah satu di antaranya adalah mikroalga menerima sedikit cahaya dengan panjang gelombang efektif diserap oleh karotenoid (violet dan merah) yang mendorong proses fotosintesis.…”

“…Intensitas cahaya yang berbeda berpengaruh secara signifikan terhadap pertumbuhan, biomassa, klorofil-a dan karotenoid. Hasil penelitian (Fakhri et al, 2017) menunjukkan bahwa peningkatan intensitas cahaya menghasilkan peningkatan pertumbuhan, biomassa, klorofil-a, dan karotenoid dari Nannochloropsis sp pada kultur skala laboratorium dengan intensitas cahaya 4.500 lux. Dari Tabel 1 terlihat bahwa intensitas cahaya matahari pada 5 stasiun di perairan Selat Bali yang berkisar antara 8.000 sampai kurang dari 10.000 lux, menunjukkan pembentukan klorofil-a yang rendah bila dibandingkan dengan pembentukan klorofil-b dan karotenoid.…”

ABSTRAKCahaya matahari merupakan salah satu faktor lingkungan terpenting baik secara langsung maupun tidak langsung bagi organisme fotosintetik perairan dalam menyediakan energi untuk diubah menjadi energi kimia dengan bantuan klorofil. Penelitian ini bertujuan untuk mengkaji hubungan antara ketersediaan cahaya matahari dan konsentrasi pigmen fotosintetik di Perairan Selat Bali. Penelitian dilaksanakan pada pagi, siang dan sore hari pada lima stasiun penelitian di Perairan Selat Bali. Analisis korelasi kanonik digunakan untuk mengetahui hubungan antara ketersediaan cahaya matahari dan pembentukan pigmen fotosintetik. Hasil penelitian menunjukkan bahwa intensitas cahaya matahari (Y2) lebih berpengaruh terhadap pembentukan pigmen klorofil-b (Y1) dengan korelasi kanonik sebesar 0,4512 bilamana dibandingkan dengan pembentukan pigmen klorofil-a (Y1) dengan nilai korelasi sebesar 0,3982. Semakin tinggi pembentukan pigmen klorofil-b (Y1) dapat meningkatkan pembentukan pigmen karotenoid (Y1) secara signifikan dengan nilai korelasi kanonik sebesar 0,7419. Kesimpulan dari hasil ini, bahwa pigmen klorofil-b dan pigmen karotenoid akan terbentuk secara optimum pada intensitas cahaya rendah. ABSTRACTSunlight is one of the most important environmental factors both directly and indirectly for photosynthetic organisms in providing energy to be converted into chemical energy with the help of chlorophyll. This study aims to examine the relationship between the availability of sunlight and the concentration of photosynthetic pigments in Bali Strait waters. The study was conducted in the morning, midday and afternoon at five research stations in the Bali Strait waters. Canonical correlation analysis was used to determine the relationship between sunlight availability and photosynthetic pigment formation. The results showed that the intensity of sunlight (Y2) had more influence on the formation of chlorophyll-b (Y1) pigments with canonical correlation of 0.4512 when compared with the formation of chlorophyll-a (Y1) pigment with a correlation value of 0.3982. The higher formation of chlorophyll-b (Y1) pigments can significantly increase the formation of carotenoid pigments (Y1) with canonical correlation values of 0.7419. From these results it can be concluded that chlorophyll-b pigments and carotenoid pigments will be formed optimally at low light intensities.

“…Juneja et al (2013) express that understanding synergistic interactions between multiple environmental variables and nutritional factors is required to develop sustainable high productivity bio algae systems. The increasing light intensity led to the increase in the growth, biomass, chlorophyll-a, and carotenoid content of microalgae (Fakhri et al 2017). Moreover, the increase of nutrient content in the waters will increase the growth of microalgae.…”

Fauziah A, Bengen DG, Kawaroe M, Effendi H, Krisanti M. 2019. Spatio-temporal distribution of microalgae producing chlorophyll and carotenoid pigments in Bali Strait, Indonesia. Biodiversitas 20: 61-67. The Bali Strait waters become a place for various development activities that connect Java Island and Bali Island so that it is thought to have an impact in the life of microalgae that play an important role in the wealth of their water resources. This study aims to explore the spatiotemporal distribution of marine microalgae, which has the potential to produce chlorophyll and carotenoid pigments, as well as their relationship with the environmental characteristics of the Bali Strait waters. The research was conducted at the 5 stations in the morning, midday and afternoon. The data obtained were analyzed using Principal component analysis (PCA) and Correspondence analysis (CA). The results showed that chlorophyll-a, chlorophyll-b and carotenoid were mostly contained by the species Chaetoceros gracilis, Tripos lunula at station 5 (Pang-pang Bay) in the morning, midday and afternoon, and contained by the species Fragilariopsis cylindrus, Thalassiothrix fravenfeldii at station 3 (Ketapang-Gilimanuk ferriage) in the midday and afternoon. Spatially, salinity, ammonia, nitrate, and chlorophyll-a have significantly different values between stations, while temporally the content of chlorophyll-b and carotenoid are influenced by time (in the morning, midday and afternoon).
