“…Filamentous bacteria have an elongated cell structure, and their colonies grow entangling each other. This particular shape was observed in activated sludges under abnormal conditions (lack of oxygen, not optimal pH) and tend to create foams . These bacteria can be either Gram-positive or negative (a parameter that defines the characteristics of their external membrane).…”

Lignin is a highly abundant biopolymer with a complex polyphenolic structure, making it a potential source of aromatic precursors, polymers, and energy. However, its thermal stability limits its economic potential, with less than 3 wt % of waste lignin transformed into commodity products. This review focuses on the chemical and biological extraction methods for lignin to promote its valorization, which involves extraction, depolymerization, and fermentation or derivatization. As there is no universal method for extraction due to the heterogeneity of lignin, a range of methods each with their advantages and disadvantages are discussed, including sulfite pulping, Kraft, Organosolv, ozonolysis, steam-explosion, ionicliquids and supercritical CO 2 extraction, and microwave-and ultrasound-assisted extraction. Biological methods, such as bacterial, fungal, and enzymatic delignification, are also explored. The review aims to provide insights to tailor extraction methods to individual needs and promote the sustainable utilization of lignocellulosic biomass.

“…The medias were incubated at room temperature for 7 days (Aghamirian & Ghiasian, 2009;Dharma Rudiansyah Rahmawati, 2019). Colonies appeared were selected for Actinomycetes bacteria which was characterized by having a powdery texture, earthy smell, filamentous growth pattern and could often produce pigments (Joseph et al, 2021;Ortenberg & Telsch, 2003). Each Actinomycetes colony was streaked on the same media (SDA) until purified isolates were obtained.…”

Actinomycetes merupakan kelompok bakteri berfilamen yang bersifat Gram-positif dan paling banyak terdapat di dalam tanah. Bakteri ini menghasilkan berbagai senyawa metabolit sekunder yang secara ekonomis sangat penting seperti antibiotik dan eksoenzim hidrolitik. Isolat Actinomycetes Laut telah berhasil diisolasi dari sedimen tanah hutan Mangrove di daerah pantai Oesapa, Kupang, Nusa Tenggara Timur. Metode isolasi dilakukan melalui pengenceran bertingkat sampel sedimen yang kemudian diinokulasi secara spread plate pada media Sabouraud Agar (SDA). Koloni yang tumbuh kemudian dipurifikasi secara streak plate dan dilanjutkan dengan uji aktivitas eksoenzim hidrolitik: Amilase, Selulase, Protease dan Lipase. Hasil uji memperoleh 6 isolat Actinomycetes yang memiliki aktivitas katalik untuk minimal empat enzim tersebut. Enzim-enzim ini dapat diarahkan pemanfaatannya dalam bidang teknologi pakan ternak khususnya sebagai imbuhan pakan yang umumnya diformulasi dalam pakan ternak untuk meningkatkan kecernaannya dalam tubuh hewan ternak. Hasil penelitian ini juga dapat semakin mengoptimalkan pemanfaatan sumber daya alam lokal khususnya dalam mendukung bidang peternakan pada skala regional.

“…The perception of smell and taste in water is attributed to different factors, such as the presence of inorganic compounds like metallic ions contributed by anthropogenic activities (mining, industrial discharges) and organic compounds of natural or synthetic origin, contributed by domestic wastewater discharges or wastewater from agricultural and livestock activities. However, in previous studies carried out by the aqueduct company, the presence of cyanobacteria has been identified in times of low flows in the Surata River, which are associated with flavor water events (Ortenberg & Telsch 2003).…”

Geosmin (GSM) and 2-methylisoborneol (2-MIB) are metabolites derived from cyanobacteria which produce taste and odor problems in drinking water treatment plants. Conventional treatment processes in water treatment are ineffective for the removal of 2-MIB/GSM. In this study, GSM and 2-MIB doses were applied to the raw water samples. Three powdered activated carbons (PAC), coconut shell, wood, and bituminous, and two oxidants, hydrogen peroxide and potassium permanganate, were evaluated. In addition, all the tests were made with and without flocculation aid (polyacrylamide). All the PACs evaluated showed better GSM and 2-MIB removals when conventional treatment was carried out with the addition of polyacrylamide as a flocculation aid. However, concentrations below the odor threshold were not reached. Regarding the oxidants, hydrogen peroxide presented the highest efficiency in eliminating GSM and 2-MIB when there is no presence of polyacrylamide.
