“…Understanding the microbial diversity of compost systems is important in order to produce high quality compost and determine its effectiveness (Krishnan et al 2017). Most studies that have explored this rich ecosystem have utilized culture-based methods (Ryckeboer et al 2003;Ahmad et al 2007; Vishan et al 2017). But, culture-based methods are only useful for identifying less than 1% of the total microbial diversity, as the majority of microorganisms are unculturable under standard media and aerobic growth conditions (Handelsman 2004;Ito et al 2018).…”

Empty fruit bunch (EFB) and palm oil mill effluent (POME) are the major wastes generated by the oil palm industry in Malaysia. The practice of EFB and POME digester sludge co-composting has shown positive results, both in mitigating otherwise environmentally damaging waste streams and in producing a useful product (compost) from these streams. In this study, the bacterial ecosystems of 12 week-old EFB-POME co-compost and POME biogas sludge from Felda Maokil, Johor were analysed using 16S metagenome sequencing. Over 10 phyla were detected with Chloroflexi being the predominant phylum, representing approximately 53% of compost and 23% of the POME microbiome reads. The main bacterial lineage found in compost and POME was Anaerolinaceae (Chloroflexi) with 30% and 18% of the total gene fragments, respectively. The significant differences between compost and POME communities were abundances of Syntrophobacter, Sulfuricurvum, and Coprococcus. No methanogens were identified due to the bias of general 16S primers to eubacteria. The preponderance of anaerobic species in the compost, and high abundance of secondary metabolite fermenting bacteria is due to an extended composting time, with anaerobic collapse of the pile in the tropical heat. Predictive functional profiles of the metagenomes using 16S rRNA marker genes suggest the presence of enzymes involved in polysaccharide degradation such as glucoamylase, endoglucanase, arabinofuranosidase, all of which were strongly active in POME. Eubacterial species associated with cellulytic methanogenesis were present in both samples.

“…Composting with natural aeration predominates in the literature reviewed studies, representing 56%. This process differs, however, from the residue disposal method, being adopted, mainly, conical cells (Karak et al, 2014;Fan et al, 2015;Pushpa et al, 2016a;Ganesh et al, 2012;Martinez-Nieto et al, 2011;Alomia et al, 2011, Parveen andPadmaja, 2011;Umsakul et al, 2010), trapezoidals cells (Singh and Kalamdhad, 2014;Taiwo et al, 2016;Kouki et al, 2016) and rotating drums (Lu et al, 2017;Rich et al, 2018;Vishan et al, 2017;Jain et al, 2020). Half of the scientific researches with natural aeration identified feature composting time equal to or less than 60 days.…”

Some of these parameters are associated with the type of study being conducted, such as specific studies of microbiology and its influence on the composting process (Pramanik, 2010;Bisen et al, 2017;Vishan et al, 2017), analysis of the decomposition of the woody fraction of macrophytes (Sarika et al, 2014;Devi et al, 2015;Das et al, 2016) or its application and potential environmental damage, to human beings and economic development (Rezania et al, 2015a;Sharma et al, 2016).…”

Macrophytes proliferation problem is worldwide know resulting in impacts on natural environment, human health and economic activities. These organisms have several parameters resilience, which ensures high rate of reproduction and proliferation, hindering their management. As a management difficulty consequence, however, solutions are sought to disposal this large amount of macrophytes, such as composting and fertilizer production. Thus, this study aims to conduct a systematic literature review in Scientific Platforms Science Direct and Scopus, identifying current status of macrophytes composting process, main methods, analyses and results obtained, in order to contribute in innovation studies to convert this type of weed into fertilizer. The general words source in titles, summary, or keywords specified by author were "Macrophyte" or "water hyacinth" and "compost" or "composting". Only articles dating from the last 20 years were maintained. Macrophyte composting process interest is addressed around the world because of their potential environmental, economic and social impacts, mainly for Eichhornia crassipes. Natural aeration predominates (56%) with composting time equal to or less than 60 days. Humidity control is essential (around 60%) like macrophytes dehydration prior to the composting process beginning. The significant quantity cellulose requires previous comminution and/or the cellulose-degrading inoculants addition. Composting process operational parameters are not standardized. Micro and macro nutrients richness can be considered for next evolutionary composting studies stage for this plant type, either by organic matter sources characteristics and/or mineral sources addition.

“…Composting efficiency is highly correlated with the presence of some other co-substrates such as manure ( Martins et al, 2020 ). The thermophilic stage is dependent on aeration and mixing rate ( Varma et al, 2018 ), and its duration could be enhanced by biochar addition ( Jain et al, 2018 ) and inoculation by some bacteria species and earthworms ( Varma et al, 2016 ; Vishan et al, 2017 ; Boonna et al, 2020 ).…”

Water hyacinth (Eichhornia crassipes L.) was introduced as an invasive plant in freshwater bodies more particularly in Asia and Africa. This invasive plant grows rapidly and then occupies a huge layer of freshwater bodies. Hence, challenges are facing many countries for implementing suitable approaches for the valorization of the world’s worst aquatic weed, and water hyacinth (WH). A critical and up-to-date review article has been conducted for more than 1 year, based on more than 100 scientific journal articles, case studies, and other scientific reports. Worldwide distribution of WH and the associated social, economic, and environmental impacts were described. In addition, an extensive evaluation of the most widely used and innovative valorization biotechnologies, leading to the production of biofertilizer and bioenergy from WH, and was dressed. Furthermore, an integrated search was used in order to examine the related advantages and drawbacks of each bioprocess, and future perspectives stated. Aerobic and anaerobic processes have their specific basic parameters, ensuring their standard performances. Composting was mostly used even at a large scale, for producing biofertilizers from WH. Nevertheless, this review explored some critical points to better optimize the conditions (presence of pollutants, inoculation, and duration) of composting. WH has a high potential for biofuel production, especially by implementing several pretreatment approaches. This review highlighted the combined pretreatment (physical-chemical-biological) as a promising approach to increase biofuel production. WH valorization must be in large quantities to tackle its fast proliferation and to ensure the generation of bio-based products with significant revenue. So, a road map for future researches and applications based on an advanced statistical study was conducted. Several recommendations were explored in terms of the choice of co-substrates, initial basic parameters, and pretreatment conditions and all crucial conditions for the production of biofuels from WH. These recommendations will be of a great interest to generate biofertilizers and bioenergy from WH, especially within the framework of a circular economy.
