“…Several studies have also reported the same result [3][25] [26]. Mesyami and Baheri (2003) reported that pine wood chips, peat moss, and Kellogg's Bran Flakes could be the bulking agents and solid amendments for degrading crude oil by white rot fungi [25]. Sari et al (2014) also reported that oil palm empty fruit branch (OPEFB) can be used as an alternative co-substrate for white rot fungi to degrade organopollutants in batches and a bioreactor [26].…”

Biodegradation of high-molecular weight polycyclic aromatic hydrocarbons (PAHs) is biologically difficult to degrade due to its recalcitrant characteristics such as low solubility in water and inhibition effect. In the present study, we used an enhanced culture system (ECS) for Bjerkandera adusta SM46 on benzo[a]pyrene (BaP) degradation under acidic (pH 4.5) and saline conditions (pH 8.2). The ECS using Tween 80 (T-80) and MnSO4 enhanced both the ligninolytic enzyme activities and degradation rate by the fungus. The optimum condition was obtained at a concentration for MnSO4 of 0.4-0.9 mM and for T-80 of 0.45-0.70%, which increased degradation more than 87% at day 30 (pH 4.5). The ECS could also be applied under a saline condition for up to 82% degradation. Mangan peroxidase (MnP) and lignin peroxidase (LiP) showed high activities at pH 4.5 (110.9 and 79.9 U/L, respectively). Moreover, laccase and MnP showed higher activities (75.6 and 130.0 U/L, respectively) at saline pH 8.2 indicating stress condition stimulation. * Corresponding AuthorTel.: +81-89-9469864; E-mail: tatibana@agr.ehime-u.ac Using rice straw also enhanced the BaP degradation rate by the fungus via cell growth promotion. This study suggests that an ECS treatment and rice straw co-substrate system could potentially enhance PAH degradation for a static batch system under both an acidic and a salinealkaline stress condition.

“…The efficiency of compost in bioremediation is essentially determined by process parameters like pH, temperature, C:N ratio, moisture content and recalcitrance of the material to be composted. Bulking agents like peat moss, pine wood shavings, bran flakes accelerate composting by favouring the growth of aerobic microorganisms [66][67][68]. Bioremediation by…”

Microorganisms play an important role in the recycling of agricultural wastes. The compost generated by bioconversion of agroresidues offers several benefits such as enhanced soil fertility and soil health which can lead to increased agricultural productivity, improved soil biodiversity, reduced ecological risks and a healthier environment. These virtues make composting an ideal option for processing of the enormous quantities of agrowastes that are generated in the world. Recent reports also indicate multifarious uses of bioaugmented compost as carrier for bioinoculants, biocontrol agents for diseases suppressivness and bioremediation. There is definite need to intensify research on novel effective microorganisms to prepare high quality compost in a relatively shorter duration and new technologies for large-scale production.

“…These microorganisms degrade PAHs cometabolically. The removal of PAHs by ligninolytic fungi has been attributed mainly to their extracellular ligninolytic enzymes [15][16][17][18], but their preference to colonize compact wood is a clear disadvantage since it limits their capability to grow in a completely different environment such as soil [19][20][21][22].…”
