High amounts of black liquor wastewater are generated from bioethanol production by using oil palm empty fruit bunches. It contains an alkaline solution (NaOH), so it is quite toxic for aquatic ecosystems if discharged directly into waters. Black liquor has been treated by coagulation method, and it still needs additional treatment. This study aimed to determine degradation of black liquor wastewater by selected white-rot fungi (WRF). Five different strains of WRF have been tested for their ability to decolorize black liquor on agar and liquid media. Out of five fungi studied, two fungi, Ceriporiopsis sp. and Phanerochaete chrysosporium, showed the capacity to grow more than 50% on agar medium. In liquid medium, the percentage of decolorization of 15,000 ppm coagulated and diluted black liquor ranged from 70 to 89% at 30 days depending on the fungal strain. Ceriporiopsis sp. showed the better ability to decolorize black liquor than P. chrysosporium. The performance of Ceriporiopsis sp was evaluated regarding decolorization of black liquor, chemical oxygen demand (COD), and mycelial dry weight both in coagulated black liquor and original black liquor. The color of original and coagulated black liquor can be decolorized up to 90.13 and 86.85%, respectively. COD in original and coagulated black liquor was reduced up to 70.17 and 40.09%, respectively. The presence of coagulant Poly Aluminum Chloride (PAC) inhibited degradation of black liquor by fungus. The result demonstrated that Ceriporiopsis sp has a potential alternative to treat black liquor wastewater.

The effects of oxygen decay (weight loss) incited by Polyporuscompactus Overh. was studied using small fresh and dried wood blocks containing both sapwood and heartwood of similar radial position and age. A manifold was used to deliver hydrated gas mixtures of 1.0, 4.2, or 21% (ambient air) oxygen at constant pressure and continuous flow to jars containing inoculated or noninoculated blocks. Means (P = 0.05) for dry weight losses in inoculated blocks at 1.0, 4.2, and 21% oxygen were 3.3, 8.9, and 21.4%, respectively; losses may be comparable to decay by other white rot fungi using the soil-block procedure. Losses in noninoculated blocks at the above oxygen levels were 2.0, 4.6, and 7.0%, respectively. Differences in dry weight losses between fresh and dry blocks were found. In particular, losses in inoculated fresh blocks were significantly less than losses in inoculated dry blocks in ambient air. Native inhabitants occurring in fresh wood appear to interfere with the decay processes of P. compactus. Losses in noninoculated fresh blocks were significantly greater than in noninoculated dry blocks at 21% oxygen but not at 1.0 or 4.2% oxygen; losses were attributed to natural inhabitants in fresh wood.

Heavy metals such as lead, chromium, cadmium, copper, mercury, and arsenic which are industrial by-products can have negative impact on the environment if they not managed properly. Biosorption is environmentally-friendly waste treatment method. The advantage of biosorption compared to other waste treatment method is ecotechnology, which means effective, cheaper than chemical treatment and environmentally-friendly technology. Using the concept of bioremediation-based on microbial enhanced recovery of metals (MERM) allows the possibility of concentration process (bio-concentration) of metal content through the process of biosorption in microbial cells. The process of bio-concentration potentially to be applied on a commercial scale to increase the recovery of high-value commercial metals. This study aims to absorb Cu2 + and Hg2 + metals using Omphalina sp. cultured on empty fruit bunches (EFB) in rotary biological contactor (RBC) systems. The principle of this technique is waste containing metals was contacted with white rot fungi (WRF) Omphalina sp. which is attached to the surface of the media inside a reactor and then the final waste concentration was analyzed. This analysis was using atomic absorption spectrometry (AAS) device to measure the concentration of Cu2+ and Hg2+ metal ions and Freundlich isothermic equations for calculating maximum absorption power (q max). The highest absorption of Cu2+ ion is 0.3304 mg/g and Hg2+ is 0.074 mg/g for 6 hours. The adsorption capacity of Omphalina sp. for Cu2 + and Hg2 + solutions based on the Freundlich adsorption equation with maximum adsorption power for Cu2 + is 71.911 mg/g and Hg2+ is 20.216 mg/g. Biosorbent Omphalina sp. can be reused in biosorption process with percentage decrease of Cu2+ is4.30% (4.3 ppm) and Hg2 + is 27.80% (1.39 ppm) for 18 hours.[Key words : biosorption technique, empty fruit bunches, immobilization, rotary biological contactor , white rot fungi-Omphalina sp.] AbstrakLogam berat seperti timbal, krom, cadmium, tembaga, merkuri, dan arsen yang merupakan hasil samping industri dapat berdampak negatif terhadap lingkungan jika tidak dikelola dengan baik.

The aim of this work was to ascertain whether a submerged culture of a white rot fungus could be used to treat distillery wastewater, and whether the compounds present in the wastewater would stimulate laccase production. Trametes pubescens MB 89, Ceriporiopsissubvermispora, Pycnoporus cinnabarinus and UD4 were screened for their ability for the bioremediation of a raw, untreated distillery wastewater as well as distillery wastewater that had been pretreated by polyvinylpolypyrrolidone. Suitability of each strain was measured as a function of decreasing the chemical oxygen demand (COD) and total phenolic compounds concentration and the colour of the wastewater, while simultaneously producing laccase in high titres. After screening, T. pubescens MB 89 was used further in flask cultures and attained 79±1.1% COD removal, 80±4.6% total phenols removal, 71±1.6% decrease in colour at an absorbance of 500 nm and increased the pH from 5.3 to near-neutral. Laccase activity in flask cultures peaked at 4,644±228 units/l, while the activity in a 50 l bubble lift reactor peaked at 12,966±71 units/l. Trametes pubescens MB 89 greatly improved the quality of a wastewater known for toxicity towards biological treatment systems, while simultaneously producing an industrially relevant enzyme.

The ligninolytic activity of Fames annosus has been estimated by radiorespirometric methods using lignocelluloses of Norway spruce and poplar, as substrates, labelled on the lignin moiety. Although F. annosus is mainly a parasite of coniferous wood, poplar lignins were more extensively degraded. 14C-labelled poplar lignocelluloses, labelled either on the lignins moiety or on the overall polymers, were used to compare wood degradation or only specific lignin degradation by the different strains. Moreover, using the best strain, we studied the effect of culture parameters which are known to influence lignin degradation by Sporotrichum pulverulentum. The rate of lignonolysis was enhanced in media with low nitrogen content but was not stimulated by increasing the O2 concentration of the atmosphere. Such data point out the specific behaviour of F. annosus, which differs in some respect from other white-rot fungi.

Effluent from the local batik home industry is a serious problem, because the effluent discharge generated is spread in different places. Untreated effluent can cause environmental pollution, such as in groundwater reservoirs,because most is discharged into rivers. The aim of this research was to evaluate the bioremediation potential of indigenous fungi in liquid culture media with Indigosol Blue 04B (IB) batik effluent. The fungi isolates tested were Aspergillus sp. 1, Aspergillus sp. 2 and Aspergillus sp. 3, isolated from dye effluent soil and batik effluent, and compared to white rot fungi (Phanerochaete chrysosporium) as a positive control.   The physiochemical properties of IB batik effluent before and after fungal treatment were investigated. All of these parameters before the fungal treatment were above the recommended standard values based on the Governor regulation of Yogyakarta Special Region No. 7/2010. The level of biochemical oxygen demand (BOD), chemical oxygen demand (COD), total dissolved solids (TDS), total suspended solids (TSS), and electrical conductance (EC) was reduce by Aspergillus spp. The highest percentage reduction was achieved by Aspergillus sp. 3, namely 88.34% BOD, 89.11% COD, 75.77% TSS, 85.85% TDS and 71.21% EC, after 3 days of incubation. These results show that the positive control isolate had the lowest value. The study confirms the ability of indigenous fungi isolates in the remediation of IB batik effluent and their potential for future analysis in the treatment of all types of batik effluent.

Leachate (liquid pollutant), which is highly contaminated with organic matter and toxic substances is a major problem that arised from landfill. Biological methods have proven to be effective to remove organic matters that are abundant in leachate. This study is intended to compare the used of free mycelia and immobilized mycelia of the white-rot fungi, Ganoderma australe for the  removal of landfill leachate organics. The organics fraction of landfill leachate was measured by biological oxygen demand (BOD5), and chemical oxygen demand (COD). The experiment revealed that free mycelia of G. australe showed capability in removing leachate BOD5  but not COD. However, the use of immobilized G. australe displayed the best result in the removal of BOD5 and COD leachate after 4 weeks of treatment in flasks with 93.09% and 17.84% percentage removal of BOD5 and COD, respectively. Therefore, G. australe can be considered potentially useful in the treatment of landfill leachate as they can help in removing BOD and COD due to their biodegradative abilities.
