Abstract
Lipolytic enzymes are important contributors in industrial processes from lipid hydrolysis to biofuel production or even polyester biodegradation. While these enzymes can be used in numerous applications, the genotype-phenotype space of certain promising enzymes is still poorly explored. This limits the effective application of such biocatalysts. In this work the genotype space of a 55 kDa carboxylesterase GDEst-95 from Geobacillus sp. 95 was explored using site-directed mutagenesis and directed evolution methods. In this study four site-directed mutants (Gly108Arg, Ala410Arg, Leu226Arg, Leu411Ala) were created based on previous analysis of GDEst-95 carboxylesterase. Error-prone PCR resulted three mutants: two of them with distal mutations: GDEst-RM1 (Arg75Gln), GDEst-RM2 (Gly20Ser Arg75Gln) and the third, GDEst-RM3, with a distal (Ser210Gly) and Tyr317Ala (amino acid position near to the active site) mutation. Mutants with Ala substitution displayed approximately twofold higher specific activity. Arg mutations lead a reduced specific activity, retaining 2.86 % (Gly108Arg), 10.95 % (Ala410Arg), and 44.23 % (Leu226Arg) of lipolytic activity. All three random mutants displayed increased specific activity as well as improved catalytic properties. This research provides the first deeper insights into the functionality of understudied Geobacillus spp. carboxylesterases with 55 kDa in size.

Abstract
Plastic pollution is one of the biggest environmental problems plaguing the modern world. Polyester-based plastics contribute significantly to this ecological safety concern. In this study, lipolytic biocatalysts GD-95RM and GDEst-lip developed based on lipase/esterase produced by Geobacillus sp. 95 strain were applied for the degradation of polycaprolactone films (Mn 45.000 (PCL45000) and Mn 80.000 (PCL80000)). The degradation efficiency was significantly enhanced by the addition of short chain alcohols. Lipase GD-95RM (1 mg) can depolymerize 264.0 mg and 280.7 mg of PCL45000 and PCL80000, films respectively, in a 24 h period at 30 °C, while the fused enzyme GDEst-lip (1 mg) is capable of degrading 145.5 mg PCL45000 and 134.0 mg of PCL80000 films in 24 h. The addition of ethanol (25 %) improves the degradation efficiency ~2.5 fold in the case of GD-95RM. In the case of GDEst-lip, 50 % methanol was found to be the optimal alcohol solution and the degradation efficiency was increased by ~3.25 times. The addition of alcohols not only increased degradation speeds but also allowed for simultaneous synthesis of industrially valuable 6-hydroxyhexonic acid esters. The suggested system is an attractive approach for removing of plastic waste and supports the principles of bioeconomics.

Abstract
Microbially induced calcite precipitation (MICP) is an efficient and eco-friendly technique that has attracted significant interest for resolving various problems in the soil (erosion, improving structural integrity and water retention, etc.), remediation of heavy metals, production of self-healing concrete or restoration of different concrete structures. The success of most common MICP methods depends on microorganisms degrading urea which leads to the formation of CaCO3 crystals. While Sporosarcina pasteurii is a well-known microorganism for MICP, other soil abundant microorganisms, such as Staphylococcus bacteria have not been thoroughly studied for its efficiency in bioconsolidation though MICP is a very important proccess which can ensure soil quality and health. This study aimed to analyze MICP process at the surface level in Sporosarcina pasteurii and a newly screened Staphylococcus sp. H6 bacterium as well as show the possibility of this new microorganism to perform MICP. It was observed that Staphylococcus sp. H6 culture precipitated 157.35 ± 3.3 mM of Ca2+ ions from 200 mM, compared to 176 ± 4.8 mM precipitated by S. pasteurii. The bioconsolidation of sand particles was confirmed by Raman spectroscopy and XRD analysis, which indicated the formation of CaCO3 crystals for both Staphylococcus sp. H6 and S. pasteurii cells. The water-flow test suggested a significant reduction in water permeability in bioconsolidated sand samples for both Staphylococcus sp. H6 and S. pasteurii. Notably, this study provides the first evidence that CaCO3 precipitation occurs on the surface of Staphylococcus and S. pasteurii cells within the initial 15-30 min after exposure to the biocementation solution. Furthermore, Atomic force microscopy (AFM) indicated rapid changes in cell roughness, with bacterial cells becoming completely coated with CaCO3 crystals after 90 min incubation with a biocementation solution. To our knowledge, this is the first time where atomic force microscopy was used to visualize the dynamic of MICP on cell surface.

Abstract
Silver nanoparticles (AgNPs) are well known for their unique physical and chemical properties, which can be incorporated into a wide range of applications. The growing resistance of microorganisms to antimicrobial compounds promoted the use of AgNPs in antimicrobial therapy. AgNPs can be obtained using physical and chemical methods, but these technologies are highly unfriendly to nature and produce large amounts of side compounds (for example, sodium borohydride and N,N-dimethylformamide). Therefore, alternative technologies are required for obtaining AgNPs. This report focuses on the biosynthesis of silver nanoparticles through the reduction of Ag+ with the cell-free secretomes of four Geobacillus bacterial strains, namely, 18, 25, 95, and 612. Only a few studies that involved Geobacillus bacteria in the synthesis of metal nanoparticles, including AgNPs, have been reported to date. The silver nanoparticles synthesized through bio-based methods were characterized using UV-Vis spectroscopy, scanning electron microscopy (SEM), dynamic light scattering (DLS), and zeta potential measurements. UV-Vis spectroscopy showed a characteristic absorbance peak at 410-425 nm, indicative of AgNPs. SEM analysis confirmed that most nanoparticles were spherical. DLS analysis showed that the sizes of the obtained AgNPs were widely distributed, with the majority less than 100 nm in diameter, while the zeta potential values ranged from -25.7 to -31.3 mV and depended on the Geobacillus spp. strain.

Abstract
Wastewater and activated sludge present a major challenge worldwide. Wastewater generated from large and small-scale industries, laundries, human residential areas and other sources is emerging as a main problem in sanitation and maintenance of smart/green cities. During the last decade, different technologies and processes have been developed to recycle and purify the wastewater. Currently, identification and fundamental consideration of development of more advanced microbial-based technologies that enable wastewater treatment and simultaneous resource recovery to produce bioenergy, biofuels and other value-added compounds (organic acids, fatty acids, bioplastics, bio-pesticides, bio-surfactants and bio-flocculants etc.) became an emerging topic. In the last several decades, significant development of bioprocesses and techniques for the extraction and recovery of mentioned valuable molecules and compounds from wastewater, waste biomass or sludge has been made. This review presents different microbial-based process routes related to resource recovery and wastewater application for the production of value-added products and bioenergy. Current process limitations and insights for future research to promote more efficient and sustainable routes for this under-utilized and continually growing waste stream are also discussed.

Abstract
In this study lipolytic biocatalysts GD-95RM, GDEst-95 and GDEst-lip were immobilized by encapsulation in calcium alginate beads. All three immobilized biocatalysts demonstrated significantly increased thermal stability at 60-70 °C temperatures and the activity of GD-95RM lipase increased by 50% at 70-80 °C following the immobilization. Moreover, encapsulated GDEst-95 esterase retained higher than 50% lipolytic activity after 3 months of incubation with butanol (25%) and ethanol (50%); GDEst-lip enzyme possessed 50% activity after 2 months of treatment with ethanol (25%) and methanol (25%); and GD-95RM lipase displayed higher that 50% activity after two-week incubation with methanol (50%). All three immobilized enzymes displayed long-term storage capability (>50% activity) at least until 3 months at 4 °C. It was also detected that immobilized GD-95RM and GDEst-lip can perform flow hydrolysis of both avocado oil and p-NP dodecanoate in prototype packed-bed column reactor. The analysis of continuous transesterification of avocado or sunflower oil with ethanol or methanol as substrates confirmed that encapsulated GD-95RM and GDEst-lip enzymes is a useful approach to produce fatty acid alkyl esters.

Abstract
The prospects of industrial uses of microbial enzymes have increased greatly during the 21st century. Fused lipolytic enzymes (where one or both fused domains possess lipolytic activity) is a rapidly growing group of industrial biocatalysts. However, the most effective fusion strategy, catalytic behavior of each domain and influence of added linkers on physicochemical and kinetic characteristics of such biocatalysts has not been yet explored. In this study the functionality of individual domains in fused lipolytic enzymes, while using GDEst-lip, GDLip-lip and GDEst-est enzymes as a model system, is analyzed for the first time. Analysis of mutant GDEst-lip, GDLip-lip and GDEst-est variants, where one domain is inactive, showed that both domains retained their activity, although the reduction in specific activity of individual domains has been detected. Moreover, experimental data proposed that the N-terminal domain mostly influenced the thermostability, while the C-terminal domain was responsible for thermal activity. GDEst-lip variants fused by using rigid (EAAELAAE) and flexible (GGSELSGG) linkers indicated that a unique restriction site or a rigid linker is the most preferable fusion strategy to develop new chimeric biocatalysts with domains of Geobacillus lipolytic enzymes.

Abstract
The gene encoding esterase (GDEst-95) from Geobacillus sp. 95 was cloned and sequenced. The resulting open reading frame of 1497 nucleotides encoded a protein with calculated molecular weight of 54.7 kDa, which was classified as a carboxylesterase with an identity of 93-97% to carboxylesterases from Geobacillus bacteria. This esterase can be grouped into family VII of bacterial lipolytic enzymes, was active at broad pH (7-12) and temperature (5-85 °C) range and displayed maximum activity toward short acyl chain p-nitrophenyl (p-NP) esters. Together with GD-95 lipase from Geobacillus sp. strain 95, GDEst-95 esterase was used for construction of fused chimeric biocatalyst GDEst-lip. GDEst-lip esterase/lipase possessed high lipolytic activity (600 U/mg), a broad pH range of 6-12, thermoactivity (5-85 °C), thermostability and resistance to various organic solvents or detergents. For these features GDEst-lip biocatalyst has high potential for applications in various industrial areas. In this work the effect of additional homodomains on monomeric GDEst-95 esterase and GD-95 lipase activity, thermostability, substrate specificity and catalytic properties was also investigated. Altogether, this article shows that domain fusing strategies can modulate the activity and physicochemical characteristics of target enzymes for industrial applications.
