“…This procedure requires the separation of non-biodegradable contaminants from a wastewater treatment plant. Sedimentation, skimming, adsorption, aeration, and flotation are physical methods of wastewater treatment ( Saravanathamizhan and Perarasu, 2021 ), as are barriers such as deep bed filters, screens, bar racks, and membranes.…”

This review presents a comprehensive summary of the latest research in the field of bioremediation with filamentous fungi. The main focus is on the issue of recent progress in remediation of pharmaceutical compounds, heavy metal treatment and oil hydrocarbons mycoremediation that are usually insufficiently represented in other reviews. It encompasses a variety of cellular mechanisms involved in bioremediation used by filamentous fungi, including bio-adsorption, bio-surfactant production, bio-mineralization, bio-precipitation, as well as extracellular and intracellular enzymatic processes. Processes for wastewater treatment accomplished through physical, biological, and chemical processes are briefly described. The species diversity of filamentous fungi used in pollutant removal, including widely studied species of Aspergillus, Penicillium, Fusarium, Verticillium, Phanerochaete and other species of Basidiomycota and Zygomycota are summarized. The removal efficiency of filamentous fungi and time of elimination of a wide variety of pollutant compounds and their easy handling make them excellent tools for the bioremediation of emerging contaminants. Various types of beneficial byproducts made by filamentous fungi, such as raw material for feed and food production, chitosan, ethanol, lignocellulolytic enzymes, organic acids, as well as nanoparticles, are discussed. Finally, challenges faced, future prospects, and how innovative technologies can be used to further exploit and enhance the abilities of fungi in wastewater remediation, are mentioned.

“…Te inoculum used had high alkalinity content and pH that provides bufering conditions that maintain the pH of the feedstock in the digester and hence will avoid the accumulation of VFA. Te biodegradability index values range from zero to unity; for complete biodegradation, BI must be above 0.3 [37].…”

“…Chemical oxygen demand (COD) was determined by the close refux through the calorimetric method [35] using a spectrophotometer (model DR-900), and BOD was determined by using a BOD incubator (model WTW ™ 208432) [36]. Substrates were weighed using an electronic precious balance (model HZT-A200), while the biodegradability index was obtained by the ratio between BOD and COD [37].…”

Increased urbanization and consumerism have resulted in the excessive release of food waste and municipal solid waste. Such wastes contain abundant organic matter that can be transformed into energy, addressing the twin challenges of waste management and energy insecurity. In recent years, different studies have investigated ways of producing biogas through the codigestion of organic wastes. In this work, different food wastes were codigested and the biogas yield was determined. The effect of feedstock mixing ratios, temperature, and pH was studied. A mixing ratio of 1 : 1 produced the highest biogas yield (2907 ± 32 mL), nearly twice, which was obtained at a ratio of 1 : 4 (1532 ± 17 mL). The biogas yield increased with the temperature rise. The lowest yield of 2907 ± 32 mL was obtained at 20°C, while the highest yield of 4963 ± 54.6 mL was obtained at 40°C. Regarding pH, the yield was 2808 ± 31 mL at pH 6.5 and 7810 ± 86 mL at pH 7.3. This indicated a 178.1% increase in the biogas yield. The CN ratio for tuber waste and fruit waste was 18 and 28, respectively, while the corresponding pH was 6.7 and 6.9. A positive synergy index of 4.5 was obtained, which is higher than what is reported in the literature of codigested substrates. Irish potato peels and banana peels produced the highest biogas yield and are recommended for use as codigested feedstock.

“…Kondisi biodegradable ditunjukkan oleh rasio BOD/COD lebih dari 0,6 sedangkan rasio yang berada pada rentang 0,3-0,6 menunjukkan kondisi perairan yang dapat didegradasi secara biologis melalui pengolahan tertentu (Tamyiz, 2015). Biodegradability index lebih dari 0,5 menunjukkan mudah terdegradasi secara biologis, dalam rentang 0,4-0,5 dapat didegradasi secara biologis dengan kecepatan sedang/ rata-rata, sedangkan di anatara 0,2-0,4 dapat didegradasi dengan lambat (Saravanathamizhan & Perarasu, 2021). Kondisi kapasitas biodegradasi yang rendah ditunjukkan pula oleh sungai-sungai yang berada di daerah urban dengan tata guna lahan yang diperuntukkan bagi kegiatan industri maupun domestik (Yustiani & Komariah,201), (Yustiani et al, 2020).…”

Permasalahan pencemaran air Sungai Cilemahabang oleh berbagai kegiatan di sepanjang kanan dan kiri sungai menunjukkan bahwa kualitas Sungai Cilemahabang telah mengalami penurunan kualitas air hingga tidak memenuhi baku mutu yang telah ditetapkan peruntukannya sebagai air baku air minum (Golongan I) berdasarkan PP No.22 Tahun 2021. Tujuan dari analisis air Sungai Cilemahabang ini adalah untuk mengetahui tingkat beban pencemar Sungai Cilemahabang, mengetahui kapasitas biodegradasi Sungai Cilemahabang, dan memperoleh gambaran untuk penyusunan rekomendasi upaya pengendalian pencemaran air Sungai Cilemahabang. Metode penelitian yang digunakan dalam penelitian ini adalah metode deskriptif. Dari hasil analisis data di dapat beban pencemar total untuk parameter BOD tertinggi pada titik 2 dan 3 yaitu 9,1 mg/L, Nilai COD tertinggi pada titik 3 yaitu 34,5 mg/L, dan Nitrat tertinggi pada titik 3 yaitu 8,5 Mg/L. Status baku mutu kualitas air Sungai Cilemahabang berdasarkan Peraturan Pemerintah RI No.22 Tahun 2021 adalah tidak dapat dimanfaatkan sesuai dengan peruntukan air kelas I. Kapasitas Biodegradasi Sungai Cilemahabang berada pada zona Non-Biodegradable dengan perbandingan rasio BOD/COD menunjukkan nilai kurang dari 0,3.
