Lipases are important enzymes involved in hydrolytic processes that bring about the breakdown of triacylglycerol to free fatty acids and glycerol. Microbial lipases have diverse applications in the various biotechnological fields such as tannery, food, detergent and pharmaceutical industries. The main purpose of this study was to isolate and characterize the lipase-producing bacteria from the effluent of a tannery located in Kasur, Pakistan. Eight bacterial strains L1, L3, L5, L6, L9, L10, L11, and L12 were isolated, followed by screening on Tributyrin Agar Medium supplemented with mustard oil. These strains were morphologically and biochemically characterized. Growth kinetic studies of these bacteria showed optimum growth at 37°C and pH 7. Sucrose, yeast extract, and olive oil were found best as carbon, nitrogen, and oil source, respectively. The bacterial strains were non- halophilic as they preferred to grow at a low salt concentration (3%). Both of the strains L5 and L10 showed good lipase activity (99 and 92U/mL) and lipase enzyme of these strains was thermostable till 67ºC with a high protein content of 321.32 and 307.02 mg/mL, respectively. The molecular weight of lipase produced by L5 and L10 varied from 32-52kDa. Among the isolated bacterial strains, two strains L5 and L10 showed high lipase activity. 16S rRNA sequencing revealed that L5 and L10 strains had 99% homology with Bacillus altitudinis. This study signifies that the tanneries can be a good source of lipase-producing bacteria and Bacillus altitudinis can be a good lipase producer.

The effect of soil selenate application to two different soils (Phaeozem and Cambisol) on biomass yield and selenium (Se) uptake by spring wheat (Triticum aestivum L.) was investigated in a pot experiment. Additionally, organic amendment (fugate, i.e. liquid by-product from the biogas plant) was applied to assess (i) the effect of organic matter on the bioavailability of Se and (ii) the fugate (containing 2.3 mg/kg of Se) as a potential source of Se for plants. Selenium was applied at two levels: 6.4 µg/kg (Se1) and 32 µg/kg (Se2) of soil. The efficiency of biofortification and the distribution of selenium within individual plant compartments were assessed in this case. The highest Se contents in the grain were achieved in the treatments receiving NPK fertiliser together with selenate, 455 µg/kg (Se1) and 2 721 µg/kg (Se2) when wheat was planted in Phaeozem. Fugate in co-application with selenate significantly reduced Se content in wheat plants as compared to treatments enriched solely with selenate. The lower Se contents in the wheat plants growing in Phaeozem were due to the biodilution effect, whereas in Cambisol, the decrease in wheat Se uptake was not clearly driven by a particular factor.

The ameliorative effects and its mitigation mechanisms of selenium (Se) on cadmium (Cd) toxicity in cucumber seedlings were studied through hydroponic experiments. Cd and other mineral nutrient concentrations, antioxidant enzyme activities, and antioxidant contents in cucumber were studied. The results revealed that exogenous Se significantly decreased the Cd concentrations in all tissues, especially in the leaves. Moreover, exogenous Se (Cd + Se) could increase Zn, Na, leaf Cu, stem/root Fe, stem/root Ca, and stem/root Mg concentrations; and reduce leaf Mg concentration, compared with Cd alone treatment. Additionally, the application of Se ameliorated the toxicity of Cd by harmonising the activities of antioxidase, such as Cd + Se treatment reduced Cd-induced increase of superoxide dismutase, glutathione peroxidase, leaf/stem ascorbate peroxidase (APX) activities, which resulted in the significant decrease of the content of hydrogen peroxide, and malondialdialdehyde; increased root APX, and glutathione reductase activities. In addition, the content of nonenzymatic antioxidants such as root-reduced glutathione and oxidised glutathione was significantly increased by adding Se under Cd stress. Also, exogenous Se enhanced the total antioxidant capacity in terms of cupric-reducing antioxidant capacity and decreased total phenols, flavonoids, and leaf/root proline contents under Cd stress. In general, 3 μmol/L Se was conducive to plant growth and improved the cucumber’s ability to alleviate Cd stress.

Exogenous carbon (C) not only regulates plant growth but also provides energy for microbes and improves the soil environment. We hypothesised that exogenous C could improve plant growth by affecting the soil environment. Therefore, pot experiments were conducted and peanut cvs. Huayu 22(H) and NN-1(B) were used under three different treatments (the control, single nitrogen (N), and N combined with glucose (CN)). The results showed that the abundance and diversity of N-fixing bacteria are obviously influenced by the C and N, and exogenous C can promote the restoration of microbial diversity. The relative abundances of Burkholderiales were increased under HCN and BCN to 9.8% and 9.5%, respectively, compared to the control (3.9%, 2.5%). The abundance of N fixation bacteria increased mainly due to the soil nutrient change. In comparison with the single N treatment, the addition of the C significantly decreased the soil NH4+-N and NO3–-N contents by 31.0% and 13.3%, respectively. And the activities of soil urease and nitrogenase were significantly increased. Compared to the control, single N significantly limited the root development, while the addition of C played a promoting role in root growth. Plant N accumulation increased compared with the control, but there was no significant difference between N treatment and CN treatment. These results indicated that exogenous C promoted soil microorganism activity and strengthened plant growth by changing the soil environment.

The effect of simultaneous intercropping of winter wheat (Triticum aestivum L.) with different legumes of faba bean (Vicia faba L.), pea (Pisum sativum L.), and purple clover (Trifolium incarnatum L.) on selected production and qualitative parameters of wheat was evaluated in field trials conducted both in organic and conventional cropping systems, in comparison with pure sown wheat. Wheat intercropped with legumes achieved higher grain yield compared to pure sown wheat for an average of two years. However, in organic cultivation, the positive effect of intercropping on wheat yields was more pronounced. In addition, a strong influence of the year was noted. In 2021, in the organic cropping system, the most yielding intercropped wheat (especially with pea and bean) achieved114–117% higher yields compared to pure sown wheat (in the previous year of 2020, it was usually only about 102–106%). In the conventional cropping system, the effect of intercropping on wheat yield was significantly weaker, and in 2021, wheat intercropped with legumes reached even lower yields than pure sown wheat in some cases. In terms of sowing methods (both in organic and conventional cropping systems), mixed sowing with individual legumes significantly exceeded the yields of wheat grown with legumes in separate, alternating rows. As regards quality parameters, wheat intercropped with legumes reached in comparison with pure sown wheat usually had higher crude protein content in wheat grain dry matter and higher values of Zeleny sedimentation.

Trees on agricultural fields can have a positive or negative impact on weed seedbank (WSB) due to diverse environmental and soil characteristics. Therefore, soil samples were drawn in six cropping systems [two agroforest systems (AFS): guava, mango; three horticulture systems (HCS): guava, mango, Indian gooseberry; and annual crop system (ACS)] at two landscape positions (lowland and upland) and two soil depths (0–15 cm and 15–30 cm) using factorial randomised block design each replicated three times. Results showed that guava-AFS had the highest WSB of different categories in general and individual weed species in particular, except for Eragrostis pilosa and Dactyloctenium aegyptium. Simultaneously, guava-AFS also showed the maximum Shannon-Weaver, species richness and Simpson index and was low in Whittaker statistics (βW). The species evenness varied non-significantly with the cropping systems. Similarly, the landscape position had no discernible effect on any weed diversity indices; however lowland landscape position was dominated by Cyperus spp. and E. pilosa, while the upland by Phyllanthus niruri. Furthermore, with the exception of βW, the WSB and diversity indices were found to be higher on the topsoil (0–15 cm). Our study establishes that the AFS system in the semi-arid sub-tropics has a more diverse WSB indicating a healthy system, as opposed to HCS, which has a dominance of certain weed species, opening the door for more severe infestation of invasive weed species.

The effects of various pre-sowing treatments of poppy seed (chemical product Cruiser OSR, stimulation products TS Osivo and Enviseed, physical treatment by E-ventus method, biological products Polyversum and Gliorex) on dynamics of field emergence, seed yield, and structure of yield parameters were evaluated in two cultivars grown in three-year trials. Seed treatment with TS Osivo and Enviseed led to a significant increase in field emergence compared to the untreated control and was on the same level as the Cruiser OSR-treated variant. In variants treated with Polyversum, Gliorex, and E-ventus, the number of emerged plants was noticeably lower. The stand density was a key factor in achieving a satisfactory yield, given that in the structure of other yield parameters (number of capsules per plant, weight of seed per capsule, and thousand seed weight), the differences between the variants were lower and often insignificant. The average yield ranged from 0.85 t/ha (Polyversum) to 1.39 t/ha (Cruiser OSR), and the stimulant seed treatments were also proved to be effective (TS Osivo 1.23 t/ha and Enviseed 1.16 t/ha). Variants with biological and physical treatment did not differ significantly from the control (0.88 t/ha) in average yield. All parameters evaluated were strongly affected by the year (weather conditions).

The aim of the experiments was to determine the effect of sowing density and nitrogen fertilisation on the cannabidiol (CBD) and Δ9-tetrahydrocannabinol (Δ9-THC) yields in selected cultivars of fibre hemp. A three-factor field experiment was conducted in 2014–2016. Factor A: cultivar (Futura 75, KC Dora and Tygra), factor B: sowing density (60 and 180 seeds/m2) and factor C: nitrogen fertilisation (0, 30, 60 and 90 kg/ha). The CBD yield ranged from 10.52 g/m2 in cv. Tygra to 10.99 g/m2 in cv. KC Dora. Among the examined cultivars, the highest yield of Δ9-THC in cv. KC Dora was observed. Sowing density did not modify the CBD yield, but increasing the density from 60 to180 seeds/m2 caused an increase in the yield of Δ9-THC in cvs. KC Dora and Tygra. Nitrogen fertilisation significantly influenced the yields of CBD and Δ9-THC. In both cases, yield increased until the rate of 60 kg N/ha.
